What Is The Difference Between HDPE And UHMWPE?

Generally HDP's production technology is extrusion, including three roll calender process and plate shaping process. And the production technology of ultra-high molecular weight PE (UHMW-PE) is compression molding pressing. In terms of thickness, the two types of products can be divided as 1. Less than 25mm, the PE sheets are usually produced by extrusion calender process.2. More than 25mm, the PE sheets can be produced either by extrusion plate shaping or by compression molding pressing.The sheets produced by calender process, with very smooth surface, shinning like a mirror.The sheets produced by compression molding pressing process, with not smooth and shinning surface. Molecular weight of HDPE and UHMW PE HDPE usually refers to the PE sheet with molecular weight less than 1.5 million.High molecular weight PE refers to PE sheet with molecular weight more than 3 million. There are 3 million, 5 million, 7.5 million, 10 million etc. molecular weight PE. The higher the molecular weight, the better the wear resistance.Ultra-high molecular weight PE has excellent properties of wear resistance, impact resistance, low temperature resistance, corrosion resistance, sanitation and non-toxicity. Performance differences between HDPE and UHMW PE Chemical resistance Both materials have excellent chemical resistance and can be used in 95% chemical environments.HDPE can't resist the corrosion of concentrated hydrochloric acid, sulfuric acid and nitric acid in high temperature, and UHMW-PE can be used to store 80 ° C hot concentrated hydrochloric acid, sulfuric acid and nitric acid, and have stable performance. Impact resistance HDPE and UHMW-PE have much better impact resistance than other plastics, such as PP, PVC. To Compare HDPE and UHMW-PE, the impact resistance of UHMW-PE is obviously better than that of HDPE, and its impact resistance absorption value is the highest among all plastics. Therefore, it is widely used in the mechanical workpieces of ships, aircraft and machine tools. Low temperature resistance HDPE can maintain good mechanical properties at low temperature - 30 ° C. UHMW-PE can still maintain excellent impact strength at -196 ° C in the liquid nitrogen, not brittle. Among all plastics, UHMW-PE has the best low temperature resistance. Environmental protection and non-toxic HDPE and UHMW-PE is environmental protective and non-toxic, easy to clean, no smell, can direct contact with food, medicine, good to replace expensive stainless steel materials.

Flame Retardant Performance Of PP Corrugated Sheet, Plastic Honeycomb Sheet & X-wall Plastic Sheet

PP corrugated sheet, PP honeycomb sheet, PP X-wall plastic sheet all of them are commonly used for packaging industries, some packaging boxes do not require flame retardant, but some for special packaging will do when used for packaging, transportation and padding of electronic products, and when used for packaging, logistics and car interior in automotive industry. Polyreflex's PP corrugated sheet, PP honeycomb sheet, PP X-wall plastic sheet can reach the UL94 standard V-0 grade. The specific conditions are as follows. UL94 flame retardant divides into three grades: V0, V1 and V2. V0 is the highest grade but price is the highest, due to its excellent flame retardant performance and difficult to do. But most customer accept V1 or V2, this is usually used in electronics, home appliances, advertising, packaging, construction, automotive industry, car interiors and other industries.How to test whether the board is flame retardant? Of course, sent it to a professional laboratory is a good choice to do testing. As a user, in order to know whether the product provided by a supplier is flame retardant or not, you can test by yourselves, this is a simple way to determine and close 80% of above cases.1. Prepared a sample size at 120x20mm.2. Clamp the sample strip 6mm from the upper part of the sample with the vertical axis vertical, and then apply the standard test flame of 10s twice. Record the residual flame time after first flame application, and record the residual flame time after second flame application. It is also necessary to record those information about whether the flame material drips from the sample.3. Based on the above information, compare the table below to determine which level the product can reach V0, V1, V2. Criteria conditions V-0V-1 V-2 Afterflame time for each individual specimen t1 or t2. ≤10s≤30s ≤30s Total afterflame time for any condition set(t1 plus t2 for the 5 specimens)≤50s≤250s≤250s Afterflame plus afterglow time for each individual specimen after the second flame application(t2 plus t3) ≤30s≤60s ≤60s Afterflame or afterglow of any specimen up to the holding clampNoNoNo Cotton indicator ignited by flaming particles of drops NoNo No 4. If only one specimen from a set of five specimens does not comply with the requirements, another set of five specimens is to be tested. in the case of the total number of seconds of flaming, an additional set of five specimens is to be tested if the totals are in the range of 51-55 seconds for V0 and 251-255 seconds for V1 and V2. all specimens from this second set shall comply with the appropriate requirement in order for the material in that thickness to be classified V0, V1, V2.5. Polyreflex’s common PP hollow sheet can reach to level V2, it extinguishes within 10 seconds from the fire with flaming material drips.Since PP honeycomb board is mostly used in vehicles and automotive interior materials, our company has conducted tests in accordance with the testing standards of automotive interior parts FMVSS302 and TSM7605G: 2006, and all of them can pass the burning speed required by customers ≤ 100mm/min..

How to do screen printing on a plastic sheet?

How to do screen printing on a plastic sheet? Screen printing is a printing technique in which ink is transferred to a substrate using a mesh, except in areas where the ink is impenetrable by means of a closed template. A blade or squeegee is moved across the screen to fill the opening of the mesh with ink. This causes the ink to wet the substrate. One color is printed at a time, so several screens will be needed to make a multicoloured image or design.What do we need to prepare for screen printing? The following items are necessary.1. Large enough well-ventilated workshop and workbench2. A screen3. A blade or squeegee4. Printing inks5. Substrate LARGE ENOUGH WELL-VENTILATED WORKSHOP AND WORKBENCH The spacious and well-ventilated workshop can ensure that workers can print more efficiently and accelerate the drying of ink. A SCREEN A screen is made of a piece of mesh stretched over a frame. The most commonly used mesh is made of polyester. There are different types of mesh sizes, which are determined by the design. The frame which holds the mesh could be made of diverse materials, such as wood or aluminum. A BLADE OR SQUEEGEE The blade is used to push the ink through the holes in the mesh.  PRINTING INKS According to the substrate, design and the use environment and requirements of final product, we will choose the most suitable ink to print. SUBSTRATE PP CORRUGATED SHEET, PP HONEYCOMB BOARD, PP FILM SHEET, PVC FOAM BOARD, PVC RIGID SHEET, ACRYLIC / PMMA These are all plastic sheets that our company can produce and offer, All of them can be screen printed. Please feel free to contact us for details if you have such printing requirement. If you would like to send us an inquiry for screen printing, please tell us the following information.1.

Can the plastic corrugated sheet, honeycomb board and X-shaped board be used outdoors?

Outdoor used material --- plastic corrugated sheet, plastic honeycomb panel and X type twin wall hollow sheet. Outdoor used, that means the material must be UV resistance, and it is used for a long time and age-resistant under the weather of sunning and raining. But how to make UV resistance? Firstly, we have to know the local outdoor used conditions for PP hollow sheets. 1. Intensity of sunlight (annual average UV exposure, continuous data for at least 10 years) .2. Moisture and annual precipitation.3. The lowest temperature. Secondly, what is the service life of PP plastic hollow board? Generally speaking, PP hollow sheet is used for advertising, truck body, construction, and other areas, the life span depends on the conditions of outdoor used and product application.Under the condition of strong ultraviolet rays, heavy precipitation, humid and the lower temperature, the aging speed of PP hollow sheet will be faster. PP hollow sheet will lose its original properties by light, heat, moisture, and other factors. We did a two-years outdoor test on regular honeycomb panels and anti-ultraviolet honeycomb panels.  The sample on the left is the original sample, and the sample on the right has been exposed to sunlight and rain for 24 months.As for the UV-resistant sample, it has not changed much after two years of testing. However, the test results of ordinary samples are not so good. Therefore, to slow down the aging speed of PP hollow sheet, the production formula can be adjusted according to different applications, here are the details how Polyreflex do. * Adding few UV resistant or antioxidant material in product, can effectively improve the atmospheric aging resistance.* To maintain the color durability, it is necessary to add weather-resistant pigments to adjust the color of the color palette, such as iron oxide red, phthalocyanine blue, carbon black, phthalocyanine green, and titanium dioxide pigments, can improve its weather resistance.* Adding appropriate amount of titanium dioxide in PP hollow sheet, not only it will not affect the original properties of the sheet, but also it can improve the atmospheric aging resistance of PP hollow sheet.* Adding appropriate antimony stabilizer to replace lead salt stabilizer in PP hollow sheet, it can improve the impact toughness and atmospheric aging resistance. For Polyreflex lightweight plastic sheets, different product has different life spans:1. PP corrugated sheet can be used outdoors for 2 years.2. PP honeycomb panel and X type twin wall hollow sheet, standard products can be used outdoors for 3 years.If the service life of 2~3 years is not enough for your application, it can be adjusted by adding high-quality UV resistance enhancer for a service life that more than 5 years.Welcome to contact us for more information.

Advantages of PP Corrugated Sheet and PP Honeycomb Panels

Both corrugated plastic sheet and polypropylene honeycomb guard are high technology hollow structure materials, with features such as lightweight, non-toxic, waterproof, anti-termite, vibration damping, anti-aging and corrosion resistant, etc. Comparison with other materials * Compared with cardboard products, fluted board and honeycomb board have the advantages of moisture-proof, waterproof, corrosion resistance, recycling, etc..* Compared with wood products, fluted sheet and honeycomb sheet have the advantages of moth-proof, moisture-proof, pollution-free and environmental protection, etc.* Compared with injection moulded products, corflute and cellular panels have the advantages of shock resistance, flexible design and no need to open injection moulds, etc. Performance enhancement lightweight board By adjusting formula or through chemical treatment of the surface, Polyreflex plastic corrugated sheets and pp honeycomb boards have excellent performance on properties such as easy printing, UV resistance, flame retardant,electrical conduction and anti-static.The surface resistivity of antistatic plate can be controlled between 106 and 1010 ohm/sq.The surface resistivity of conducting electrostatic plate can be controlled between 103 and 105 ohm/sq.

The difference between polypropylene and polyethylene sheet

Polypropylene Sheet is a kind of thermoplastic product made by polymerization of propylenea, it includes Copolymer Polypropylene and Homopolymer Polypropylene Sheet.Polypropylene material is non-toxic, tasteless and waterproof with low density, it can use at around 100℃. It has good chemical stability and easy for vacuforming. The disadvantage of polypropylene sheet is low wear resistance and easy to crisp under low tempreture. Polyethylene Sheet is a thermoplastic product made by polymerization of ethylene.Polyethylene material is odorless, non-toxic, with excellent low temperature resistance at -100~-70 °C. It has stable chemical properties and it’s an excellent electrical insulation product. Polyethylene (PE) Sheet mainly includes HDPE Sheet, LDPE Sheet and LLDPE Sheet.The most popular product is HDPE sheet. HDPE is a high-density polyethylene, it’s a highly HDPE is a non-polar thermoplastic material with high crystallinity.  Both PP and HDPE is widely used in food packaging. They look simiar but they are difference in performance. --- HDPE has higher strength and stiffness than PP.--- HDPE has a better performance on heat resistant, low temperature resistance, anti-aging and toughness than PP.--- The transparency of PP is better than HDPE.--- The price of PP is a little lower than HDPE.--- HDPE is mostly used for structural parts and various parts, while PP is mostly used for water tanks, electroplating tank, containers and others. Use of polypropylene sheet and polyethylene sheet HDPE sheet PP sheet Method for distinguishing between PP and HDPE sheets --- The surface of the HDPE sheet is self-slip, you can touch the surface of the board to distinct. Generally, the surface and sides of HDPE sheet are smooth and feel like a candle, while the side of the PP sheet will produce some burrs and it’s rough.--- The combustibility is different, check the following form.

What should I pay attention to when using a corona treated PP corrugated sheet?

1) Keep the pp corrugated sheet clean The corona-treated sheet has a strong adsorption force for dust. We recommend that the PP corrugated sheet used for printing should be wrapped by PE film and stored in a clean, dust-free warehouse. Check the following PP corrugated board wrapped by PE film. 2) Try not to paste a sticker on corona-treated panels Try not to paste a temporarily used sticker on the corona-treated PP corrugated sheets because it has a strong adsorption to the glue. The glue will penetrate into the surface of the sheet and is difficult to remove. 3) The best service life of corona-treated panels is six months After six months, the corona effect will diminish. Therefore, it is recommended to print and use polypropylene corrugated board within half a year to ensure the best results.
