- Functions:Antioxidant
- Features:Oxidation Resistant, Improves Process Stability, Increased Tensile Strength, Crack Resistant, Impact Resistance
Most polymers go through oxidative degradation processes during manufacturing and subsequent compounding and processing. Oxidation and heat aging are major causes of degradation of plastics. Exposure to heat and oxygen causes a chain reaction involving the formation of free-radicals, which inevitably leads to cleavage of the main chains in the polymer and degradation of the plastic. This is manifested in many difference ways including loss of shine and transparency, yellowing, surface cracking and odors. Oxidation can also result in loss of mechanical properties such as impact resistance, elongation and tensile strength.
