1 CHINOX S35 Antioxidant and Thermal Stabilizer General CHINOX S35 is a high molecular weight hindered phenolic antioxidant. It is an effective sulfur-containing stabilizer that does not discolor, and ensures heat stability over the long term by preventing thermo-oxidative degradation. Suggested use for CHINOX S35 is the process stabilization of polyethylene wire and cable resins.

CO., LTD. DATA SHEET ANTIOXIDANT Methanol 5% Mineral Oil Toluene 50% Water < Application CHINOX S35 is a sulfur-containing antioxidant and heat stabilizer that is widely used for stabilization of polyethylene cable and wire resins. CHINOX S35 eliminates the concern over micro-contaminants that can affect the insulation properties of the wire, and it also prevents premature gel formation of chemically crosslinked polyethylene during extruder compounding. CHINOX S35 provides efficient processing stabilization and long-term thermal stability with excellent system compatibility and low color that can also be applied in styrenic polymers, polypropylene , elastomers such as EPDM and SBR and for carboxylated SBR latex, polybutadiene rubber and polyisopropene rubber CHINOX S35 also provides excellent stabilization in other petroleum products such as turbine oil and in petrolatum, and higher alphaolefins such as 1-butene and 4-methyl-1 pentene plus polyurethanes, polyesters, segmented block copolymers, ABS, and other rubber modified polymers.
