A1010 Antioxidant

Chemical Name: Pentaerythritol Tetrakis (β-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate)
Application : A1010 is a sterically hindered phenolic antioxidant with a highly effective non-discoloring stabilizer for organic materials. It protects these materials against thermo-oxidative degradation. A1010 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, PVC, styrenic like IPS, ABS, elastomers like SBS, SEBS, EPM, and EPDM as well as synthetic rubbers, adhesives tackifier and other organic substrates.
A1010 has good compatibility, high resistance to extraction and low volatility, odorless. It can be seed in combination with other additives like costabilizers (e.g.thioesters, phosphites. Phosphonices) light stabilizer and other functional stabilizers. The synergistic blends at A1010 with A168 are extreme performonce in polymers stabilization .

A168 Antioxidant

Chemical Name: Tris-(2.4-di-tert-butylphenyl)-phosphite Application : A168 is a hydrolytically stable phosphite processing stabilizer as a secondary a n tioxida n t. It reacts during processing with hydroperoxides formed by autoxidation of polymers preventing process in duced degradation. A168 reacts with hydroperoxides to yield non-radical products, therefore is called hydroperoxided composer. A168 can be synergistically combined with other primary antioxida n t such as A1010 and A1076 for use i n polyolefins or olefin -copolymers such as HDPE, LLDE, PP, EVA as well as PC, PA. The blends can also be used in eng neering plastics such as PBT, PER and styrenics, elastomers like PS, ABS BR, SBS and tickifier resins, adhesives. A168 protects polymers which are prone to oxidation during processing steps (compounding, pelletizing, fabrication and cycling) from molecular weight change (e.g. chain scission of PP, crosslinng of PE) and prevents discoloration.

A626 Antioxidant

Chemical Name: Bis(2.4-di-t-butylphenyl) Pentaerythritol Diphosphite Application :A626 is an antioxidant of the high performance organic phosphate. It can nicely protect the polymer's color and luster. Comparing with other phosphate, and the result is more good. Generally, it not apply to the polymer singly. Usually, after compositing with the phenolic main antioxidant(A1010), the phosphate just be used. Can increase the hot stability of polymer in the process. After compositing with the phenolic main antioxidant. It is extensive to be used for the PP, PE, PS polyamide polycarbonate ABS, etc. A626 can in crease the polymer's stability in the course of mix, produce and usage, reduce the degradation of polymer in process. Under the many applications, it has the high performance. Very low dosage is required for effective resin protections. Comparing with other equivalent t phosphate, it has the higher phosphorus content. Can improve the light-stability of polymer. It can be used as potentiating agent of benzophenone, benzotriazole.
