Application:

* Primary antioxidant for organic polymers.

* High performance sterically hindered phenolic antioxidant that

protects the polymer against thermo-oxidative degradation during the manufacturing processes and in end-use applications

* An effective antioxidant for styrenics, synthetic rubbers, POM homo & copolymer, polyurethanes, polyamides, polyesters, MBS and PVC

* Low volatility, good color stability, and extraction resistant

* Chain Stopper in PVC and ABS manufacturing process

* Fish Eye reduction in flex-PVC application

* Can be used with benzotriazoles or HALS for thermal and light stabilization

in outdoor use.

* Exhibits a synergistic effect when used in combination with hioester antioxidants

 

STORAGE：Keep containers tightly closed in a dry, cool and well-ventilated place。
