(Polyethylene) Specific gravity: 0.94-0.96 g/cm3 Mold shrinkage: 1.5-3.6% Molding temperature: 140-220℃ Material performance Corrosion resistance, excellent electrical insulation (especially high-frequency insulation), can be chlorinated, modified by irradiation, and can be reinforced with glass fiber. Low pressure polyethylene has a melting point, rigidity, hardness and strength, low water absorption, and good The electrical properties and radiation…

(Polypropylene) Specific gravity: 0.9-0.91 g/cm3 Mold shrinkage: 1.0-2.5% Molding temperature: 160-220℃ Material performance Low density, strength and rigidity, hardness and heat resistance are better than low-pressure polyethylene, and can be used at about 100 degrees. It has good electrical properties and high-frequency insulation. It is not affected by humidity, but it becomes brittle at low…
