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(dá)-269以下℃，仍有一定機(jī)械強(qiáng)度。

耐磨性

超高分子量聚乙烯具有極佳的耐磨性，分子量越高，材料的耐磨性越好。

4、耐化學(xué)品性

UHMWPE具有優(yōu)良的耐化學(xué)品性，除強(qiáng)氧化性酸液外，在一定溫度和濃度范圍內(nèi)能耐各種腐蝕性介質(zhì)（酸、堿、鹽）及機(jī)介質(zhì)（荼溶劑除外）。

其在20℃和80℃的80種機(jī)溶劑中浸漬30d，外表無任何反?，F(xiàn)象，其它物理性能也幾乎沒有變化。

5、沖擊能吸收性

UHMWPE具有優(yōu)異的沖擊能吸收性，沖擊能吸收值在所有塑料中最1高，因而噪聲阻尼性能很好，具有優(yōu)良的削音效果。

6、耐低溫性

UHMWPE具有優(yōu)異的耐低溫性，在液氦溫度（-269℃）下仍具有延展性，因而能夠用作核工業(yè)的耐低溫部件。

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
