UHMW Anti-static Sheet is an ideal material to use when potentially volatile conditions exist, such as those in grain elevators and munitions plants, effectively safeguarding against static discharges. 8 main features of the UHMW Anti-static Sheet are follows:
1, A high impact resistance. The impact strength and UHMW polyethylene on its molecular weight, molecular weight less than 2,000,000, with the increase of the molecular weight, the impact strength increased,
2, To improve wear resistance. The most striking increase in molecular weight polyethylene is that it has a high abrasion performance, this performance has many engineering applications are very valuable.
3, A low coefficient of friction. UHMWPE is very wearable, and low coefficient of friction, good self-lubricating, is an ideal bearing bushings, sliders, lining materials.
4, Low water absorption. UHMWPE water absorption is very low, it is almost non-absorbent, does not swell in the water, much less absorbent than nylon.
5, Good chemical resistance. Ultrahigh molecular weight polyethylene having a good resistance to chemical corrosion properties, in addition to concentrated nitric acid, concentrated sulfuric acid, it will not corrode at all alkali, acid, and can be applied at a temperature (80 ℃ of concentrated hydrochloric acid, in <20% of nitric acid, <75% sulfuric acid is stable, its water, liquid detergent is also stable.
6, Non-toxic UHMWPE tasteless, non-toxic, odorless, non-corrosive itself, through physiological and physiological adaptation, the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA) to allow it to use in contact with food and medicines occasions.
7, The thermal properties. Measured by ASTM (load 4.6kg/cm2) method, heat distortion temperature of 85 ℃, in a smaller load, temperature up to 90 ℃, in exceptional circumstances, allows the use of higher temperatures, due to the super-high molecular weight polyethylene is an excellent material toughness, so its performance is very excellent low-resistance, low temperature at -269 ℃, still has some ductility, and no signs of embrittlement.
8, The electrical properties. Ultra high molecular weight polyethylene in a wide range of temperatures, have a very good electrical properties, its volume resistivity of 10-18CM, the breakdown voltage of 50KV/mm, the dielectric constant of 2.3. In a wide range of temperature and frequency, its electrical properties change little.
