low friction paper machinery UHMWPE suction box cover
UHMWPE(Ultra-high Molecular Weight Polyethylene) wear resistance dewater element is used for paper manufacturing machinery. Dewater element component includes: suction box covers, Doctor blade,Forming board,Scraper blade and so on. UHMWPE had used in parts of paper manufacturing machinery widely.
1. Excellent Abrasion-resistance
2. Good self-lubrication and low coefficient of friction
3. High anti-impact strength and good toughness
4. Good chemical corrosion resistance can resist almost all mediums such as acid,alcli and salt,but except for concen trated sul-phuric-acid,concentrated nitric and a few organic solvents.
5. Inodorous,in noxious and impenetrable
6. Good conductibility and ultra-low water absorbability
7. Good anti-environmental stress breakage property which is 200 times of ordinary ethylene
8. Good cold resistance property which isnit brittle even if at 176°Cbeiow zero.
