The mechanical abrasion resistance of the polymer polyethylene board can be described as invincible

High molecular polyethylene board has excellent abrasion resistance, good low temperature impact resistance, self-lubricity, non-toxic, water resistance, chemical resistance, heat resistance is better than general PE, the disadvantage is heat resistance (thermal deformation Low temperature), poor processability, external surface hardness, rigidity, creep resistance are not as good as general engineering plastics, and the expansion coefficient is too large. UHMWPE has poor fluidity and extremely high viscosity in the molten state. It is a rubber-like high-viscosity elastomer. It could only be formed by pressing and sintering methods in the early days. It can also be processed by extrusion, injection molding and blow molding.

The mechanical properties of the high-molecular-weight polyethylene board are higher than that of general high-density polyethylene. It has outstanding impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical resistance, fatigue resistance, noise damping, and nuclear radiation resistance. The coal bunker lining board has a temperature of 100 ~ 110 ℃. Good cold resistance, can be used at -269 ℃. A product with a density of 0.935 g / cm3 and a molecular weight of 2 million has a tensile strength at break of 40 MPa, an elongation at break of 350%, a bending elastic modulus of 600 MPa, and a notched Izod impact.
