表2 UHMWPE 与其它工程塑料密度比较

Ultra

high molecular weight polyethylene sheet English abbreviation is UHMW-PE board.

origin of ultra high molecular weight polyethylene board is USA. That is an

American invention and production of ultra high molecular weight polyethylene

sheet. Ultra high molecular weight polyethylene sheet is a kind of thermoplastic

engineering plastic, its production process is packing - heating - pressure -

temperature - die. Although it is made very simple, actually otherwise ultra high molecular weight polyethylene board

production must have certain experience and unique technology, especially the

ratio of raw materials and the heating and cooling time directly affect the

performance of ultra high molecular weight polyethylene plate.

of ultrahigh molecular weight polyethylene board: light weight, impact

resistance, abrasion resistance, corrosion resistance, ultraviolet resistance,

aging resistance, low friction coefficient, non-toxic, non polluting, not easy

adhesion, excellent performance of foreign body can absorb the vibration and

noise etc.. Is the best material instead of metal material. Use the plate to

manufacture products of other properties of ultra high molecular weight

polyethylene due to metal products available
