What are the factors affecting UHMWPE board

Ultra-high molecular weight polyethylene sheet is also called low-pressure high-density polyethylene sheet, which belongs to a highly crystalline, non-polar thermoplastic resin. Someone asked Xiaobian whether the molding of UHMWPE sheet would be affected by temperature? I believe many manufacturers are more concerned about this issue, so next I will introduce it to you in detail.

The temperature of the UHMWPE board has a great influence on the product quality. We should control the temperature in the middle of the mold slightly lower than the temperature at both ends. We should have uniform and stable temperature conditions to assist. The die lip spacing is equal to or slightly less than the thickness of the polyethylene sheet. The uniform and stable temperature ensures a stable flow and equal pressure in the volume of the extruded melt, and makes the longitudinal thickness error of the sheet small. The mold temperature control should be stable. The temperature will affect the melt flow rate, so the thickness error of the formed UHMWPE sheet is relatively large.
