EPT plastic Upe Sprocket wheel
UHMW-PE&lparUltra high Molecular Excess weight Polyethylene &rparis a thermoplastic engineering plastic with the regular molecular excess weight a lot more than 9&period0 million&period &lparPE only has the molecular bodyweight in between twenty to two hundred thousand&interval &rpar This kind of content with five top overall performance of substantial-put on-resistance&comma good-chemical resistance&comma minimal-temperature resistance&comma self-lubrication and substantial-influence resistance&comma which is regarded as a “stunned” engineering plastic of superb comprehensive potential and aggressive price&period of time
Primary traits&colon
one&time period Really large-put on resistance&comma 7 times wear resistance than metal&comma four moments than PTFE
two&interval Very higher anti-influence resistance&comma two instances affect resistance than Laptop&comma 5 instances than Abs&period
three&period Good self-lubrication&comma the identical as PTFE&comma greater than metal and brass appended lubricating oil&time period
4&period Excellent anti-corrosion resistance&comma it has extremely stable chemica EPT property and can endure the corrosion of
All types of corrosive medium and natural and organic solvent in particular rang of temperature and humidity&period of time
5&period of time Really substantial-inadhesion resistance&comma the surface area of merchandise hardly affixes EPT content&time period
6&period of time Quite high-affect resistance&comma ten moments impact resistance than PA66&comma eight instances than PTFE&interval
seven&time period Very good lower temperature resistance&comma in liquefied nitrogen &lpar- 196º C&rpar&comma it even now has the prolongation&period
Couple of EPT materia EPT can reach to this performance&period
eight&interval Non-poisonous and clean house&comma UHMW-PE&comma which is the material that Food and Drug Administration &lparFDA&rpar and United States Office of EPT &lparASDA&rpar allow to implement in food and medicine fields&time period
