The basic properties of UHMW-PE sheet:

1, UHMW-PE sheet low water absorption. UHMW-PE sheet water absorption is very low, it is almost non-absorbent, does not swell in the water, much less absorbent than nylon.

2, UHMW-PE sheet excellent chemical resistance. UHMW-PE board has good resistance to chemical corrosion properties, in addition to concentrated nitric acid, concentrated sulfuric acid, it will not corrode at all lye, acid, and can be applied at temperatures 80oC of concentrated hydrochloric acid at <20 % nitric acid, <75% sulfuric acid is stable, its water, liquid detergent is also stable.

3, UHMW-PE sheet thermal properties. Measured by ASTM (load 4.6kg / cm2) method, heat distortion temperature of 85oC, under a small load, temperature up to 90oC, in exceptional circumstances, allow the use at higher temperatures, due to the UHMW-PE plate is a material excellent in toughness, so its performance is very excellent in low-resistance, low temperature at -269oC, still has some ductility and no signs of embrittlement.

4, UHMW-PE sheet very low coefficient of friction. UHMW-PE sheet are very resistant, and low coefficient of friction, good self-lubricating, is an ideal bearing bushings, sliders, lining materials. Use UHMW-PE sheet equipment as friction components, in addition to improving wear life, it can also receive energy saving effect.
