What are the main varieties of PP modified plastics used in automobiles?
(1) toughened PP material, which is mainly elastomer based toughening, has very high impact strength and low temperature toughness. It is mainly used to make automobile bumpers, and adding toughening agents can achieve good results.(2) filling is filled, toughened by inorganic materials toughened by elastomer modified PP material, has outstanding advantages of high modulus, rigidity and good heat resistance, good dimensional stability, overcome the general contraction PP material rate, low thermal deformation temperature, mechanical durability poor, widely used in the manufacture of the car inside and outside decoration, such as instrument panels, door trim board, water tank cover etc..
PP modified plastics are divided into the following 3 categories according to specific parts:Modified plastics for interior decoration of automobileAutomotive special modified plasticsSpecial modified plastics for automobile functional parts
Reinforced glass fiber reinforced PP material is the highest strength, rigidity, heat resistance and dimensional stability of polyolefin plastics. It is mainly used to produce high strength and high heat resistant products such as engines, fans, etc..
