超高分子量聚乙烯（UHMWPE）綜合了所有塑料的優(yōu)越性能，其耐沖擊、耐磨損、耐化學(xué)腐蝕、自身潤(rùn)滑、吸收沖擊能這五個(gè)特性是目前即存塑料中所具有的最1高數(shù)值，這種新型塑料制品的杰出性能在歐美各國(guó)受到普遍重視。

超高分子量聚乙烯樹脂是由乙烯、丁二烯單體在催化劑的作用下聚合而成的粘均分子量大于150萬(wàn)～700萬(wàn)的熱塑性工程塑料，被稱為"神奇的塑料" 。

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
