PP 聚丙烯、臺灣臺化 、K1010 特性應用
Automotive industry (primarily the use of metallic additives PP: Fender, ventilation pipes, fans, etc), appliances (dishwasher door gasket, dryer vent pipes, washing machine framework and machine cover, refrigerator door liners etc), consumer goods (lawn and garden equipment such as lawnmower and sprinklers, etc)

1. crystalline material, the moisture absorption of small, prone to melting of rupture, long-term contact with the hot metal can decompose.
2. good fluidity, but shrink and shrink the scope value, prone to cratering. dents, deformation.
3. cooling speed, feed system and slow cooling in the cooling system and control the temperature. melt temperature at the low temperature and high pressure easier orientation, die when the temperature is below 50 degrees, not smooth plastic parts, easy to produce poor welding, flow marks, more than 90 degrees prone to warping deformation
