| 机械性能高于一般的高密度聚乙烯。具有突出的抗冲击性、耐应力开裂性、耐高温蠕变性、低摩擦系数、自润滑性，卓越的耐化学腐蚀性、抗疲劳性、噪音阻尼性、耐核辐射性等。 Mechanical properties are higher than general high density polyethylene. It has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance and so on. 使用温度100～110℃。耐寒性好，可在-269℃下使用。密度0.935g/cm3，分子量200万的产品，其断裂拉伸强度40MPa，断裂伸长率350％，弯曲弹性模量600MPa，悬臂梁缺口冲击冲不断。磨耗量(MPC法)20mm。 The temperature ranges from 100 to 110 C. It has good cold resistance and can be used at - 269 C. The product with density of 0.935g/cm3 and molecular weight of 2 million has fracture tensile strength of 40 MPa, elongation at break of 350%, flexural modulus of elasticity of 600 MPa, and impact impact of notch of cantilever beam. The wear rate (MPC method) is 20 mm. |
