Irganox PS 800 Didodecyl-3,3'-thiodipropionate 123-28-4 Ciba Antioxidants >> Thioester Heat stabilizer for PVC plastisols Polyvinyl Chloride (PVC) Polyolefins (PE, PP…) ADHESIVE IRGANOX PS 800 is a dialkyl ester of thiodipropionic acid. It is used as a heat stabilizer in combination with a phenolic antioxidant. Polymer materials requiring long-term thermal stability Polyethylene power cables XLPE power cables HDPE pipe Polypropylene Polyolefin under-hood automotive applications Styrene homo- and copolymers Adhesives IRGANOX PS 800 used in combination with a primary phenolic antioxidant provides general purpose heat stabilization. With the highest compatibility and lowest melting point of common thiosynergists, it is most easily incorporated into the final product. It is most widely used in combination with IRGANOX 1035 for peroxide cross-linked power cables. Improve the long-term heat stability of polymers . Dialkyl ester of thiodipropionic acid. Used as a heat stabilizer in combination with a phenolic antioxidant in adhesives. Provides general purpose heat stabilization. Possesses high compatibility and low melting point. Use level : 0.05-1%.
