Antioxidants are organic compounds which are incorporated at low concentrations to inhibit or retard polymer oxidation and its ensuing degradative effects.
Anti-oxidant masterbatches prevent thermal degradation and provide long term stability. Rapid offers two categories of antioxidant masterbatches:
Primary Anti-oxidants: These are used to protect the finished goods. These are incorporated for ensuring the performance of product over the life of product.
Secondary Anti-oxidants: These are used as process stabilizers. They protect the product during processing.
The masterbatches are available at 10 & 20 % active ingredient and the dosage recommended are around 1 – 3 % levels. Although this is a standard grade with us, but we are always keen to develop the required products to meet your needs. The choice of antioxidant depends on factors such as compatibility, colour and thermal stability, volatility and stabilizer efficiency.
