PE plastic bag is short for polyethylene. It is a thermoplastic resin polymerized from ethylene. Polyethylene is odorless and feels like wax. It has excellent low temperature resistance (low temperature use temperature can reach -70~-100℃), good chemical stability, resistance to most acids and bases (not resistant to oxidation acid), ordinary solvent at room temperature, small water absorption, excellent electrical insulation performance. High pressure polyethylene has the advantages of high melting point, high hardness, high strength, low water absorption, good electrical function, high radiation intensity, high impact resistance, fatigue, wear resistance, impact resistance, corrosion resistance, high elongation, high impact resistance, leakage resistance, corrosion resistance and so on.
Its characteristics are as follows:
1.Crystal material, small moisture absorption, good fluidity, fluidity sensitive to pressure, molding should use high pressure injection, uniform material temperature, fast filling speed, sufficient pressure.
2.Wear resistance - provides long-term protection for the appearance of many high-precision machining.
3.Impact resistance - Maintain the integrity of the appearance in many applications where the impact is not strong.
4.Puncture resistance - can form a tough barrier to the liquid, so that it can not corrode the product.
5.Flexibility - adapt to most surface shapes.
6.Easy to use - polyurethane offers a solution for many rigorous uses.
7.Non-volatile machine components - Volatile machine components are not released when used.
PE bag has excellent corrosion resistance, electrical insulation (especially high frequency insulation), chemical modification, radioactive modification, can enhance the glass fiber. It has low melting point,high stiffness, hardness and strength.Its Water absorption capacity is small. Low pressure polyethylene has good electrical and radioactive properties, with softness, elongation, impact strength and high leakage rate, with high impact strength. Fatigue and wear resistance. Low pressure polyethylene is suitable for the manufacture of corrosion resistant parts and insulation parts; High pressure polyethylene is suitable for making thin films.
