Anti-Oxidant Masterbatch

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. Oxidation create may problems including loss of shine and transparency, yellowing, surface cracking and odours. Oxidation can also result in loss of mechanical properties such as impact resistance, elongation and tensile strength. Anti-Oxidant Masterbatch Are Used to extend the life and strength of polymers, antioxidant masterbatch helps protect plastic products from degradation caused by outside elements such as ultraviolet light, oxygen, heat, and humidity.

Antioxidant masterbatch allows for improved control of the polymer manufacturing process by increasing dispersion efficiency leading to cost savings. Anti-oxidant masterbatch interrupt autoxidation in different ways according to their chemistry and molecular weight. Oxidation can be eliminated by Primary Antioxidants that interrupt the primary oxidation cycle by removing the propagating radicals and Secondary Antioxidants that stop the oxidative cycle by preventing or inhibiting the formation of free radicals.

Anti-Oxidant Masterbatch can offer better stabilization of the polymer during processing and also prolong its useful life in the end application .Long term color and thermal stability can be enhanced by selecting the correct package of antioxidants to be added to the masterbatch

FAQ Anti-Oxidant Masterbatch

Anti-Oxidant Masterbatch is used to improve the thermal stability, oxidation resistance, and long-term durability of plastic products during processing and service life.

It is widely used in polyethylene films, polypropylene products, plastic pipes, injection molded components, packaging materials, and various polymer-based products.

It helps prevent polymer degradation, improves product appearance, extends service life, and maintains mechanical properties during high-temperature processing and outdoor exposure.

Anti-Oxidant Masterbatch can be formulated for compatibility with PE, PP, and other thermoplastic polymers depending on the required application.

You can find a suitable supplier in Iran for Anti-Oxidant Masterbatch through Irancorps, which connects international buyers with verified Iranian manufacturers and suppliers.

Important factors include antioxidant concentration, carrier resin compatibility, processing conditions, application requirements, quality standards, and supplier reliability.
