MY9800 polyphenylene sulfide (PPS) toughening agent is a sulfide ester copolymer synthesized independently by our company, containing silicone flexible segments and reactive end groups. It is particularly suitable for toughening PPS/glass fiber and carbon fiber systems. It can significantly improve impact strength without reducing other strengths such as tensile and bending strengths. It can also be used in blends of PPS, PPO with PA, HIPS, PC, and corresponding alloy fiber-reinforced systems as a toughening compatibilizer to enhance compatibility and overall performance.

Compared to the unprocessed MY9800 sample, the impact strength has increased by 4KJ/M², while other rigidity indicators remain basically unchanged.
