Physical properties:
Soluble in chloroform, cyclohexane, n-hexane, methylene chloride, toluene, sparingly soluble in methanol, acetone, insoluble in water. Low volatility and particularly resistant to hydrolysis.
Performance and Application:
Antioxidant FWEOS 68 is a hydrolytically stable organo-phosphite processing stabilizer. As a secondary antioxidant, FWEOS 68 reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process induced degradation and extending the performance of primary antioxidants. It can be applied in polyolefins and olefin-copolymer such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers as well as polycarbonates and polyamides. The blends can also be used in polyesters, styrene homo-and copolymer, adhesives and other organic substrates. The amount to be used may be 0.05%~0.2%.
Storage and packaging：
Keep containers tightly closed in a cool, well-ventilated place. Paper-plastic composite bags or cardboard boxes with PE film bag inside, net weight 25kg, or according to customers’ requirement. Period of Validity: Normally 24 months.
