What are the tougheners for plastic extrusion materials

Toughening agents for plastic extrusion materials mainly include the following types:

1. Rubber elastomer toughening: EPR (ethylene propylene diene), EPDM (ethylene propylene diene), butadiene rubber (BR), natural rubber (NR), isobutylene rubber (IBR), nitrile rubber (NBR), etc. ; Suitable for toughening modification of plastic resins used;

2. Thermoplastic elastomer toughening: SBS, SEBS, POE, TPO, TPV, etc.; mostly used for toughening polyolefins or non-polar resins, and used for toughening polymers containing polar functional groups such as polyesters and polyamides. A compatibilizer needs to be added;

3. Core-shell copolymer and reactive terpolymer toughening: ACR (acrylate), MBS (methyl acrylate-butadiene-styrene copolymer), PTW (ethylene-butyl acrylate-methyl Glycidyl acrylate copolymer), E-MA-GMA (ethylene-methyl acrylate-glycidyl methacrylate copolymer), etc.; mostly used for toughening engineering plastics and high-temperature resistant polymer alloys;

4. High-toughness plastic blending and toughening: PP/PA, PP/ABS, PA/ABS, HIPS/PPO, PPS/PA, PC/ABS, PC/PBT, etc.; polymer alloy technology is used to prepare high-toughness engineering plastics important ways;

5. Other methods of toughening: nanoparticle toughening (such as nano-CaCO3), sarin resin (DuPont metal ionomer) toughening, etc.;
