Anti-Oxidant & Anti-Ozonant
Antioxidants and antiozonants play essential roles in enhancing the durability and lifespan of rubber materials. Here’s an introduction to these additives in the context of rubber compounds:
Antioxidants for Rubber Compounds: Rubber materials are prone to degradation when exposed to oxygen, heat, and environmental factors. Antioxidants are incorporated into rubber compounds to safeguard against oxidative degradation. These compounds inhibit the oxidation process by scavenging free radicals and interrupting the chain reaction of oxidation.
Antioxidants can be classified into primary and secondary types:
-
Primary Antioxidants: Primary antioxidants, also known as hindered phenols, are highly effective in preventing the initiation of oxidation. They react with free radicals, breaking the chain reaction and safeguarding the rubber from degradation. Common primary antioxidants used in rubber compounding include butylated hydroxytoluene (BHT), hindered phenols, and hindered amine light stabilizers (HALS).
-
Secondary Antioxidants: Secondary antioxidants, such as amines and phosphites, work in conjunction with primary antioxidants as co-antioxidants. They scavenge and neutralize intermediate oxidation products, extending the protective effects provided by primary antioxidants.
Antiozonants for Rubber Compounds: Apart from oxidative degradation, rubber materials are susceptible to degradation caused by exposure to ozone. Ozone, present in the atmosphere, can react with unsaturated bonds in rubber, leading to cracking and deterioration of rubber compounds. Antiozonants, also known as antiozonants or antiozonants, are added to rubber formulations to protect against ozone-induced degradation.
Antiozonants function by creating a protective barrier on the rubber’s surface, preventing ozone from reaching the underlying rubber molecules. Common antiozonants used in rubber compounding include waxes, fatty acids, and chemical compounds like paraphenylene diamine (PPD).
Both antioxidants and antiozonants are crucial additives in rubber compounding processes. They help maintain the integrity and performance of rubber materials, increasing their resistance to aging, cracking, and degradation caused by oxidation and ozone exposure.
