UHMWPE identification method: temperature measurements. Pure UHMWPE ultra high molecular weight polyethylene Order slider at 200 degrees Celsius is not melted, not deformed UHMWPE sliders, but become soft. If it is not pure UHMWPE material at 200 degrees Celsius there will be deformed. UHMWPE forming: a porous membrane. Since the formation of the skeleton structure has limited the UHMWPE gel contraction slider prices, generating pores in the drying process, the maximum porosity biaxially stretched without destroying the complete porous structure. This material can be used as water, oxygen through clothing fabrics and chemical resistance, it can be used as an ultrafiltration / microfiltration membrane, battery separator composite films and so on.
