Is a new type of high molecular weight phosphite antioxidant, with good thermal stability and hydrolysis stability, low volatility, in the humid environment, can still maintain a good hydrolysis stability, and blocked phenolic antioxidant combination, than the traditional phosphite class auxiliary antioxidant can significantly improve the processing stability of the material. In the process of high temperature processing and application, it can provide excellent anti-yellowing and high temperature degradation protection, suitable for polymers requiring good thermal stability energy.
In addition, propylene, polypropylene systems often require phenol-free antioxidant to avoid reaction with other additives, it acts as a phosphite antioxidant, used alone can still maintain high efficiency
Suitable for: processing conditions of polymer materials, such as high temperature processing of engineering plastics and special engineering plastics.
Add amount: 0.05-0.2%, the specific add amount is determined according to the customer application test.
Packed in 25 Kg / carton. Or packed as per customers requirements.
Store appropriately in a dry area below 25 C with a shelf life of two years.
