What Is The Advantage Of PE Sheet Compared To Ordinary Plastic Sheet?

May 16, 2019

The raw material of the PE sheet is heated for a short period of time between 140 ° C and 275 ° C for 1 to 30 minutes, which can effectively improve some physical properties of the sheet. Compared with unheated UHMPWE products, the former has better physical properties and transparency, and the smoothness and low-temperature mechanical properties of the product surface are greatly improved. At the molding processing temperature, the PE sheet will also have a decrease in melt viscosity due to oxidation, discoloration, and streaks, so care should be taken during the molding, processing, or material selection of the pe sheet. If you want to treat the oxidation of pe sheet products, you need to modify them. The method of modifying pe sheets is to add UV-resistant reagents and antioxidants.

PE board is PE (polyethylene) with good chemical stability and can resist the erosion of most acids, alkalis, organic solutions and hot water. The electrical edge is good and easy to weld. Divided into HDPE board (high density polyethylene board) and LDPE board (low density polyethylene board) according to thickness: HDPE board has good heat resistance and cold resistance, high rigidity and toughness, and good mechanical strength. The density of LDPE board is 0.916~0.930g/cm3, which is soft in nature.
