1、極高的耐磨性

UHMW-PE制品的獨特分子結(jié)構(gòu)，使它具有超然的抗滑動摩擦能力。耐磨性高于一般的金屬和塑料制品，是碳鋼的6.6倍，不銹鋼的5.5倍，黃銅的27.3倍，是酚醛樹脂的17.9倍，尼龍的5倍，PTFE的5倍。

2、極高的耐沖擊性

在現(xiàn)有的工程塑料中本產(chǎn)品的沖擊韌性值高，許多材料在嚴重的沖擊中會裂紋、破損、破碎或表面能力疲勞，本產(chǎn)品按GB1843標準，進行懸臂梁沖擊試驗達到無破壞。

3、良好的耐化學腐蝕性

本產(chǎn)品可以耐烈性化學品的侵蝕，除對某此強酸在高溫下有輕微腐蝕外，在其它的堿液，酸液中不受腐蝕，對海水，液體洗滌劑性能也很穩(wěn)定。

4、很低的磨擦系數(shù)

由 于本產(chǎn)品內(nèi)含蠟狀特質(zhì)，磨擦系數(shù)（196N，2小時）僅為0.219MN/m（GB3960）自身潤滑性很好，自身滑動性能優(yōu)于油潤滑的鋼和黃銅；特別是 在環(huán)境惡劣、灰塵、泥沙多的地方，本品的自身干潤滑性能更充分的顯示出來，不但能運動自如，且保護相關(guān)工作不被磨損、拉傷。

5、表面非附著性

本產(chǎn)品由于磨擦系數(shù)小和無極性，具有很好的表面非附著性�，F(xiàn)有的材料一般在PH值為9以上的介質(zhì)中均結(jié)垢，本品則不結(jié)垢。這一特性對火電站用于排煤粉灰系統(tǒng)有重大意義。

6、其它特性

本產(chǎn)品還有吸能、吸噪音、抗靜電、不吸水（6％）、比重輕、耐候性好、容易機械加工、可著色等突出特性。

上述特性是本產(chǎn)品的基本特性，還可以根據(jù)各種不同的需要，加入添加劑進行改性，如：增強強度、阻燃性等。

1, extremely high wear resistance

The unique molecular structure of UHMW-PE products makes it have a transcendent ability to resist sliding friction. The wear resistance of metal and plastic products is 6.6 times that of carbon steel, 5.5 times of stainless steel, 27.3 times of brass, 17.9 times of phenolic resin and 5 times of PTFE of nylon.

2, extremely high impact resistance

In the existing engineering plastics, the impact toughness of this product is high, many materials will crack, break, break or surface fatigue in severe impact. According to GB1843 standard, the impact test of cantilever beam can reach no damage.

3, good chemical corrosion resistance

This product can resist the erosion of strong chemicals, except for the slight corrosion of a strong acid at high temperature, the other lye, acid solution is not corroded, and the performance of the liquid detergent is also very stable to the sea water.

4, very low friction coefficient

Because of the waxy quality contained in this product, the friction coefficient (196N-1 / 2 hours) is only 0.219mn / m (GB3960) self-lubricity, and its sliding performance is superior to that of oil-lubricated steel and brass, especially in places where the environment is harsh, dust and sediment are high, The dry lubrication performance of this product is more fully displayed, not only can move freely, but also protect the related work from wear and tear.

5 . Surface non - adhesion

Due to small friction coefficient and no polarity, this product has good surface non-adhesion. The existing materials generally scale in the medium with PH value above 9, but not in this product. This characteristic is of great significance for coal ash removal system in thermal power station.

6, other characteristics

This product also absorbs the energy, absorbs the noise, the antistatic, does not absorb the water (6%), the specific gravity is light, the weather resistance is good, easy to machine processing, can coloring and so on outstanding characteristic.

The above properties are the basic properties of the product, and can be modified by adding additives according to various needs, such as: strengthening strength, flame retardancy and so on.
