Antioxidant 3114 Plastic / Rubber Antioxidant Additive Cas
The antioxidant 3114 is a trifunctional hindered phenol type antioxidant, which is non-polluting and non-colored. Since the molecular weight and the melting point are high, the volatility is extremely small, the mobility is small, and the water extraction resistance is good, and the plastic is excellent in thermal oxidation resistance and photooxidation resistance.

Antioxidants: hindered phenols. Abstract Monohydric phenols differing in steric hindrance of the phenolic moiety and in their character of substitution at position 4 are typical chain-breaking antioxidants for commodity and engineering plastics. They have been used as processing stabilizers at temperatures up to 300°C, e.g. in polyolefins.

Sterically hindered phenolic antioxidants have a positive effect on the long-term thermal stability (LTTS) of polypropylene. However, the molecular weight of these additives and their structural properties confer different effects. Phenolic antioxidants such as AO3 (Butylhydroxytoluène) are too volatile and are physically lost in short time.
Send InquiryPolymer stabilizers
Stabilizers are a class of chemical additives commonly added to polymeric materials, such as plastics, to inhibit or retard their degradation. Polymers can be subject to various degradation processes, including oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues or other impurities. These processes all degrade the polymer on a chemical level, leading to chain scission that can adversely affect its mechan
