UHMWPE極高的分子量，而且屬于價(jià)格適中、性能優(yōu)良的熱塑性工程塑料，它幾乎集中了各種塑料的優(yōu)點(diǎn)，具有普通聚乙烯和其它工程塑料無(wú)比擬的耐磨、耐沖擊、自潤(rùn)滑、耐腐蝕、吸收沖擊能、耐低溫、衛(wèi)生無(wú)毒、不易粘附、不易吸水、密度較小等綜合性能。事實(shí)上，目前還沒(méi)有一種單純的高分子材料兼有如此眾多的優(yōu)異性能。UHMWPE的耐磨性居塑料，并超過(guò)某些金屬，圖1為UHMWPE與其它材料耐磨性比較。從圖1可以看出，與其它工程塑料相比，UHMWPE的沙漿磨耗指數(shù)僅是PA66的1/5，HEPE和PVC的1/10；與金屬相比，是碳鋼的1/7，黃銅的1/27。這樣高的耐磨性，以致于用一般塑料磨耗實(shí)驗(yàn)法難以測(cè)試其耐磨程度，因而專(zhuān)門(mén)設(shè)計(jì)了一種沙漿磨耗測(cè)試裝置。UHMWPE耐磨性與分子量成正比，分子量越高，其耐磨性越好

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
