EVERFOS-168reactswith hydroperoxides to yield non-radical products, therefore called hydroperoxide decomposer. EVERFOS-168 is synergistically combined with other primary antioxidant such as EVERNOX-10 and EVERNOX-76 for applied used in polyolefins or olefin-copolymers such as HDPE, LLDPE, PP, EVA as well as PC, PA.The blends can also be used in engineering plastics such as PBT, PET, and styrenics, elastomers like PS, ABS, BR, SBS and tickifier resins, adhesives. EVERFOS-168 protects polymers which are prone to oxidation during processing steps (compounding, pelletizing, fabrication and recycling) from molecular weight change (e.g. chain scission of PP, crosslinking of PE) and prevent discoloration.Hydrolytic StabilityUnlike other organic phosphites, EVERFOS-168 shows no water absorption even after 4 months storage at 20℃and 80% relative humidity.Handling & SafetyEVERFOS-168shouldbe handled with care and prevent contamination of the environment.Avoid dust formation and ignition sources. For more detailed information please refer to the material safety data sheet.PackingThe following packages are available upon customer’s request： (1) 25 kgs×2 PE bags in a carton box. (2) 50 kgs fiber drum. (3) Other specific request.TransportationEVERFOS-168 is not a dangerous goods according to the transportation regulations.StorageEVERFOS-168 be stored under suitable conditions (dry & cool). Maximum recommended storage time from the date of analysis：24 months.

We, established in 1988 under our parent company Sunko Group, are a fast-growing chemical company that produces high-qualily and cost-effective antioxidants for the polymer industries. We currently have about 50 staffs, including both office and factory workers.In 1969, the first Sunko company, Sunko Chemical Co., Ltd., was founded in Taichung and was one of the leaders in the field agrochemicals in Taiwan. With continuous study and development, Sunko Group had established the following subsidiaries and expanded many fields of products to serve customers
