BreckTech 168
Breckenridge Technologies · BreckTech
BreckTech 168 is a phosphite antioxidant that appears as a white powder or granules. It provides excellent hydrolysis resistance and low volatility, enhancing processing stability in polymers by minimizing molecular weight changes and discoloration. Commonly used as a secondary antioxidant, it stabilizes materials such as polyethylene, polypropylene, and styrenic polymers, making it suitable for a variety of plastic applications. It is typically used at concentrations of 0.05% - 0.5% depending on the application.
- High stability
- Broad UV absorbance
- High hydrolytic resistance
- Thermally Stable
