What are the measures to improve the compressive resistance of ultra high molecular weight polyethylene sheet? 2013-05-29how enhances the impact resistance, impact strength, and molecular weight of polyethylene liner polyethylene liner, which is less than 2000000, and with the increase of molecular weight, the impact strength increases by about 2000000, reaching a peak, then peak, molecular weight and increased impact strength. This is because the molecular chain is very disturbing to the effect of the crystal lamp, in the amorphous region can absorb the larger impact energy of macromolecules. According to the literature, the impact strength of ultra-high molecular weight polyethylene and other plastics astm-d256 method of the determination of the value, through comparison: Impact can be divided into impact polycarbonate comparable ultra-high molecular weight polyethylene at room temperature conditions, applied to engineering plastics. Ultra-high molecular weight polyethylene plate even at low temperature, also has the impact resistance is absurd, even in the liquid and gas temperature-269oc, can also better impact resistance, low this good temperature characteristics, so that ultra-high molecular weight polyethylene extended to low-temperature engineering applications.
