Application Fields of Impact Modifier

Impact Modifier is an additive that can improve the impact resistance of plastic products and is widely used in the production of various plastic products. There are many types of impact modifiers, which can be divided into the following categories based on their compatibility and dispersibility with the matrix plastic:
-Elastomeric Impact Modifiers: Impact modifiers mainly composed of rubber or elastomers, such as styrene butadiene rubber, acrylic rubber, chlorinated polyethylene, etc., have poor compatibility with the matrix plastic and form dispersed phases, which can absorb impact energy and improve the toughness of plastic products. The elastic impact modifier is mainly used to modify brittle plastics such as polystyrene, polyvinyl chloride, polycarbonate, etc.
-Core shell impact modifier: It is mainly composed of copolymers with a core shell structure, such as acrylate butadiene styrene copolymer, methyl methacrylate butadiene styrene copolymer, etc. They have good compatibility with the matrix plastic, form a continuous phase, and can improve the impact strength and surface gloss of plastic products. The core shell impact modifier is mainly used to modify brittle plastics such as polystyrene, paraformaldehyde, and nylon.
-Nucleophilic Impact Modifier: It is mainly composed of copolymers containing nucleophilic groups, such as maleic anhydride grafted polypropylene, maleic anhydride grafted polyethylene, etc. They have excellent compatibility with the matrix plastic and form a blend phase, which can improve the impact resistance and processing performance of plastic products. The nucleophilic Impact Modifier is mainly used to modify crystalline plastics such as polypropylene and polyethylene.
The application fields of Impact Modifier are very extensive, involving industries such as packaging, construction, automotive, electronics, and healthcare. For example:
-In the packaging industry, Impact Modifier can be used to improve the impact resistance and transparency of plastic products such as PET and PVC, enhance their low temperature and aging resistance, and extend their service life.
-In the construction industry, Impact Modifier can be used to improve the impact resistance and weather resistance of plastic products such as PVC and PC, enhance their UV and fire resistance, and increase their safety and aesthetics.
-In the automotive industry, Impact Modifier can be used to improve the impact and wear resistance of plastic products such as ABS and PA, improve their oil and chemical corrosion resistance, and reduce their weight and cost.
-In the electronics industry, Impact Modifier can be used to improve the impact resistance and Vicat softening temperature of plastic products such as PS and POM, improve their high temperature and voltage resistance, and ensure their stability
