10 Common Plastic Toughening Agents

In the production of plastic products, plastic toughening agents are key to enhancing material performance. Below are 10 common combinations of plastic toughening agents.

I: PC Toughening Agents — MBS and EMA

PC is prone to cracking at low temperatures, while MBS has good compatibility with PC and can absorb impact energy. EMA enhances the toughness of PC due to its flexibility. Together, they improve the impact resistance of PC, making it suitable for electronic and electrical enclosures, among other applications.

II: PP Toughening Agent - Weidamei EPDM and TPO

PP has poor low-temperature toughness. Vistamaxx improves impact resistance and transparency. EPDM enhances flexibility, while TPO balances rigidity and toughness, and is used for car bumpers, etc.

Three: PE Crack Resistant Heroes - Metallocene PE and POE

PE is prone to cracking, metallocene PE enhances strength and toughness, and POE prevents cracking with its high elasticity and compatibility, used in films and pipes.

Four: ABS Toughening Solutions - High Rubber Powder, SBS, and TPEE

ABS is insufficient for applications requiring high toughness. High rubber powder increases the rubber phase content, SBS absorbs impact, and TPEE improves impact resistance and fatigue resistance, used for mobile phone cases.

5: PS Toughening Agent—SBS and K Resin

PS is hard and brittle, SBS improves toughness, K resin enhances impact strength and gloss, used in stationery and daily necessities.

6: Nylon Toughening Agent - EPDM Grafting and POE Grafting

Nylon is sensitive to gaps, while EPDM grafting and POE grafting enhance compatibility and prevent crack propagation, and are used for automotive engine components.

7: PVC Toughening Agent - Traditional CPE and Low-temperature PTW

PVC has poor toughness, CPE improves processing and toughness, and PTW enhances impact resistance at low temperatures, used for door and window profiles.

8: Toughening Agents for PPT and PET — POE Grafted with GMA, PTW, and EMA

PPT and PET are gap-sensitive, and POE grafted with GMA enhances compatibility and toughness. PTW and EMA improve toughness, used for fibers and films.

POM has low impact strength, TPU forms a dispersed phase when blended with POM, absorbing energy and enhancing toughness, and is used for automotive parts.

Ten: PPS High-Temperature Resistant Toughening Agent — SEBS Grafting

PPS has poor toughness, and SEBS grafting enhances compatibility, improving toughness while maintaining high temperature resistance, and is used in the aerospace field.

Different plastics have varying characteristics and application scenarios. Choosing the right toughening agent combination is essential to fully leverage the advantages of plastic properties.
