Product description:
UHMWPE rod has excellent abrasion resistance, low temperature impact resistance, self-lubricity, non-toxic, water and chemical resistance, heat resistance which is better than that of ordinary PE. The disadvantages are low heat-resistance (thermal deformation temperature), poor processing and moulding performance. Its surface hardness, rigidity and creep resistance are not as good as those of general engineering plastics and its expansion coefficient is a bit larger. UHMWPE has poor fluidity and extremely high viscosity in the molten state. It is a rubber-like high-viscosity and elasticity subject. At the early stage, it can only be molded by pressing and sintering. Now it can be processed by the methods of extrusion, injection molding and blow molding.
Its mechanical performance is better than that of ordinary high density polyethylene. It boasts excellent impact resistance, stress cracking resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping resistance and nuclear radiation resistance, etc.
