Product Description

Ultra-high molecular weight polyethylene scraper is mainly used in scraper conveyor, buried scraper, sweeper and other transportation equipment; Ultra high molecular weight polyethylene scraper non-toxic, tasteless, can be used in food machinery; 
Also known as: polyethylene scraper, polymer scraper, conveyor scraper high self-lubrication, no water absorption -- destruction due to water absorption to form molecular chains, eliminate bonding, natural smooth feeding. 
High wear resistance, impact resistance -- add a variety of amendments, maintain the original characteristics, improve more practical advantages. Impact resistance -- impact strength up to 150KJ/㎡, no rupture. 
Excellent low temperature resistance, even at 176℃ is not brittle. 

Features
1. Wear resistance: static friction coefficient is 0.07; 2. Self-lubricating: smooth surface, no roughness; 3. Impact resistance: good impact resistance without damage; 4. Corrosion resistance: can resist acid, alkali, salt and other corrosion; 5. Non-adhesion: no water absorption, small surface tension is not easy to scale; 
Size: Customized products, customers need to provide drawings, according to customer requirements for processing and production. 

Application
1, paper industry: vacuum box panel, dewatering board, scraper, sealing strip, paper cutter bushings, etc. 
2, beverage and food machinery: the use of high quality, impact resistance, non-bonding, health and non-toxic, the production of work plate, conveyor screw, gear, etc. 
3, water treatment: sewage treatment plant sludge scraper, screw conveyor lining plate, mud pump impeller, pump shaft sleeve, clarifying device gear and sedimentation tank lining plate, etc. 
4, textile machinery: the use of impact resistance, high performance and self-lubricating, such as 36 gear, shuttle bomb frame machine buffer flapper, bearing lining, etc. 
5. Medical instruments: human implants, artificial joints, orthopedic instruments and stents, surgical instruments. 

Advantages 
* Characteristics of high molecular weight polyethylene polyethylene pad, polyethylene hard pad has high flexibility, static friction coefficient of 0.07. 
It can be used in concentrated hydrochloric acid at 80℃, and its performance is stable in 75% concentrated sulfuric acid and 20% nitric acid. 
Polyethylene pad can be at -269 ℃ low temperature, has a certain ductility. Large volume resistance, breakdown voltage up to 50KV/mm, dielectric constant of 2.3. Polyethylene hard pad sanitary non-toxic: tasteless, non-toxic, odorless, non-corrosive. It is a kind of engineering plastic with excellent performance, 
Such as plate high **, impact resistance, very low friction coefficient, good self-lubrication performance, excellent low temperature resistance, chemical corrosion resistance and so on.
