【Product application】

Relysorb^®9228 is widely used in high temperature engineering plastics such as PC, PA66, PET, PBT, etc., to replace conventional small molecular weight phosphite antioxidants

(which are prone to degradation or evaporation or hydrolysis at high temperatures and lose most of their effectiveness).
Due to its exceptional heat stability (Td 330~ 350℃) and volatile resistance, Risubao? 9228 has also been used more and more successfully in high temperature nylon, processing temperature of special engineering plastics such as polysulfone, polyethersulfone, liquid crystal polymer (LCP) systems, effectively improve the thermal stability of high temperature melt processing, chromatism resistance and melt rheological stability.
