>Material performance density is small, strength, stiffness, hardness and heat resistance are better than low-pressure polyethylene. It can be used at about 10°C. It has good electrical properties and high-frequency insulation and is not affected by humidity. Impact, but becomes brittle at low temperatures, is not resistant to molds and easily ages. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Crystal material with good molding properties. It has low hygroscopicity and is prone to melt rupture. Long-term contact with hot metal is prone to decomposition. Good, but the shrinkage range and value are large, shrinkage marks are prone to occur, and the deformation speed is fast. The pouring system and cooling system should dissipate heat slowly, and pay attention to controlling the molding temperature. The directionality is obvious when the temperature is low, especially when the temperature is high and the mold temperature is low. When the temperature is above the degree, the plastic parts are not smooth and are prone to poor welding and marks. When the temperature is above the degree, the plastic parts are prone to warping and deformation
The wall thickness of the material must be uniform to avoid lack of glue and sharp corners to prevent stress concentration
