HDPE sheet and UHMWPE sheet have different manufacturing processes, namely extrusion process and compression molding process. Different manufacturing processes bring them different properties.
PE sheet refers to a thermoplastic sheet with polyethylene as the main raw material. We supply PE sheet types including LDPE sheet, HDPE sheet and UHMWPE sheet. PE sheet has the advantages of high toughness, excellent tensile strength, abrasion resistance, corrosion resistance, low temperature resistance, and high processability.
Both LDPE sheet and HDPE sheet are produced by extrusion process, while UHMWPE sheet is manufactured by compression molding process.
In this blog, we will share their manufacturing process through video.
HDPE stands for High Density Polyethylene, a durable and widely used thermoplastic. It provides high impact strength, high wear resistance and toughness over a wide temperature range of -50ºC to 80ºC. HDPE sheet is resistant to corrosion, mildew and rot, which makes it extremely durable in a variety of environments.
Our HDPE sheet can be produced in a maximum width of 3 meters. The extrusion process means that its length is unlimited. You can customize the length of the board according to your needs. The thickness of HDPE sheets ranges from 0.4mm to 200mm. White and black are our most frequently produced colors, and its colors can also be customized.
UHMWPE refers to polyethylene with an average molecular weight of more than two million, also known as UPE, its full name is ultra-high molecular weight polyethylene. The performance of UHMWPE is superior to that of HDPE in all aspects, and it can be used where friction resistance, impact resistance, ultra-low temperature and corrosion resistance are required. Excellent chemical and mechanical properties make UHMWPE sheet widely used in electric power, marine, coking, coal, paper, textile, chemical and other industries.
The manufacturing process of UHMWPE sheet is to pour the powdered polyethylene raw material into the compression mold. Under high temperature and high pressure, the raw material is melted and fixed by a steel plate for several hours, and finally a flat board is formed. It can be known from this that the size of the UHMWPE sheet is determined by the size of the mold. We have multiple molds in different sizes, welcome to contact us for the producible size of UHMWPE sheet.
