Insight into the PP plastic
PP plastic English name: the proportion of Polypropylene: 0. 9 - 0. 91 g/cm3 molding shrinkage rate: 1. 0 - 2. 5% molding temperature: - 160 220 ℃ drying conditions: - - - - - - - - - - - - - Material properties density is small, the strength stiffness, hardness, heat resistance are better than that of low pressure polyethylene, can be used in 100 degrees. Has good performance and high frequency insulation is not affected by humidity, but low temperature time-varying crisp, not resistant to aging. Suitable for making general machinery parts, corrosion parts and insulation parts molding performance 1. Crystalline material, small hygroscopicity, prone to melting body burst, long-term contact with the hot metal is easy to decompose. 2. Liquidity is good, but the scope and contraction value is big, prone to shrinkage cavity. Dent, deformation. 3. Cooling speed, gating system and cooling system should slow cooling, and pay attention to control the mold temperature. Low temperature the direction clear direction. Especially when high pressure at low temperature, mold temperature is lower than 50 degrees, the plastic parts is not smooth, easy to cause weld adverse, vestiges of 90 degrees or more prone to buckling deformation. 4. Plastic wall thickness should be uniform, to avoid the lack of glue, sharp corners, to prevent stress concentration.
