It protects these materials against thermo-oxidative degradation. EVERNOX-10 can be applied in polyolefins, such as PE, PP and olefin copolymers like EVA. Also its use is recommended in various polymers such as POM, PA, PUR, PES, PBT, PET, PVC, styrenic like IPS, ABS, elastomers like SBS, SEBS, EPM and EPDM as well as synthetic rubbers, adhesives tackifier and other organic substrates. EVERNOX-10 has good compatibility, high resistance to extraction and low volatility, odorless. It can be used in combination with other additives like costabilizers (e.g. thioesters, phosphites, phosphonites), light stabilizer and other functional stabilizers. The synergistic blends of EVERNOX-10 with EVERFOS-168 are extreme performance in polymers stabilization. Handling & Safety EVERNOX-10 and EVERNOX-10GF should be 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. Packing The following packages are available upon customer’s request： (1) 20 kgs paper bag. (2) 25 kgs ×2 PE bag in the carton box. (3) 50 kgs fiber drum. (4) Other specific request. Transportation EVERNOX-10 and EVERNOX-10GF are not dangerous materials according to the transportation regulations. Storage EVERNOX-10 and EVERNOX-10GF be stored under suitable conditions (dry & cool). Maximum recommended storage time from the date of analysis：60 months.
