耐寒性

高密度聚乙烯分子量超過50萬時，脆化溫度降至-140℃。超高分子量聚乙烯甚至可以在液氮或液氦下作用，其使用溫度可達-269以下℃，仍有一定機械強度。

耐磨性

耐沖擊性

UHMWPE的沖擊強度，在所有工程塑料中名列前茅，圖2為UHMWPE與其他工程塑料沖擊強度比較，從圖2中可以看出，UHMWPE的沖擊強度約為耐沖擊PC的2倍，ABS的5倍，POM和PBTP的10余倍。耐沖擊性如此之高，以致于采用通常沖擊試驗方法難以使其斷裂破壞。其沖擊強度隨分子量的增大而提高，在分子量為150萬時達到最1大值，然后隨分子量的繼續(xù)升高而逐漸下降。值得指出的是，它在液氮中（-195℃）也能保持優(yōu)異的沖擊強度，這一特性是其它塑料所沒有的。此外，它在反復(fù)沖擊表面硬度更高。

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
