Uhmw-pe*** molecular weight polyethylene bar performance characteristics
1. The chemical stability of polyethylene rod is excellent, and the ability to resist acid, alkali, alcohol, oil, water, etc. is strong.
2. The electrical properties of polyethylene rods are excellent and are ideal high-frequency insulation materials
3. Polyethylene rod tensile strength and bending strength are high
4, polyethylene rod molding performance is excellent, its water absorption is small, can not be dried before molding; shrinkage is small, the size of the product is stable; the specific heat capacity is small, can be heated and plasticized very quickly, the amount of plasticization is large, so the molding speed is fast, the production cycle is short, and high-speed injection can be carried out; the fluidity is good, and various molding methods such as injection, extrusion, and vacuum can be used.
5, polyethylene bar is a kind of excellent performance of thermoplastic engineering plastics, with ordinary polyethylene and other engineering plastics *** various advantages, polyethylene bar has a very high impact resistance, very low water absorption, very low friction coefficient, excellent self-lubrication, excellent non-stick, excellent acid and alkali *** properties.
6. Polyethylene bar is chemically resistant to chemical corrosion ***, and can withstand the corrosion of any acidic substance.
7. Polyethylene rod is odorless and has no exudate, which can improve environmental efficiency. Polyethylene rod has good electrical resistance and extremely low water absorption. The excellent environmental stress cracking performance of polyethylene rods is 200 times that of ordinary polyethylene.
