1. What is pp toughener?
Plastics need to add tougheners during the production process to adjust their toughness. pp tougheners are used in ABS, Toughening and compatibilizing reagent for HIPS, PP, PC, PC/ABS and PA modified products.
PP toughening agent is a type of impact performance reinforcing agent for modified products produced based on a multi-component blending system and using two-way grafting reaction technology as a process route for different modified products. It overcomes the It overcomes the application limitations of the traditional compatibilizer produced by a single base material and a single grafting process. On the premise of toughening and compatibilization, it also takes into account that other physical properties of the modified product will not be significantly reduced as a result, and the comprehensive performance Very excellent.
PP has poor impact resistance, especially when used at low temperatures. Therefore, when PP is used in engineering structural materials or products with higher performance requirements, it often needs to be toughened and modified.
2. What are pp toughening agents
pp There are many toughening agents. For general toughening of PP, EPR, EPDM, LDPE, EVA, CPE, SBS, POE, TPU, polybutadiene rubber, styrene-butadiene rubber, polyisobutylene rubber, butadiene rubber and natural rubber can be used. Toughening agent for rubber and other elastomers. Among them, EPDM, LDPE, POE and SBS are the most commonly used. Terpolymers of PP can also be used, such as PP/EPR/LDPE, PP/EVA/polyisobutylene, PP/LDPE/EVA, PP/LDPE/EPDM, PP/EPDM/SBS and PP/TPU/SBS, etc.
3. What are the product specifications of pp tougheners?
There are many product specifications of pp tougheners, among which the more commonly used ones are the following. :
1. Multi-component blended two-way graft PS510
Translucent particles, grafting rate 1.5%, good fluidity, used for ABS, The toughening and compatibilization of HIPS, PP, PC, PC/ABS, and PA modified products can help improve the fluidity of the product and can be directly used for injection molding.
2. Multi-component blended two-way graft PS512
Light yellow semi-transparent particles, grafting rate 0.8%~1.2%, used for PP, PC, HIPS, PToughening and compatibilization of C/ABS, PBT, PET, PA modified products.
3. Multi-component blended two-way graft PS535
Natural color semi-transparent sheets or granules, grafting rate 1.5%, used for PA, PET , Toughening and compatibilization of PP and PBT modified products.
4. Polypropylene blended two-way graft PS566
Transparent particles, grafting rate 0.8%~1.2%, good fluidity, used for PP modification, toughening and compatibilization of PBT/PP blended products can help improve product fluidity.
