Applications

OMNISTAB ® HP-136 is high effective carbon free radical trapped and chain-breaking antioxidant. It is used to stop Auto-oxidation of polymer during production by trapping free radical. OMNISTAB ® HP-136 can provide reactive hydrogen increasing the efficiency of the phenolic antioxidant and decreasing the dosage of phenolic or phosphite antioxidants. OMNISTAB ® HP-136 is suitable especially for high temperature production condition,which make it as an important stabilizer for propylene in processing. OMNISTAB ® HP-136 is useful in BOPP film,PC,Styrene,PPR pipes,Polyurethane and Adhesives and etc.
