B900 can be dissolved in solvents such as benzene. choroform and ethly acetate. The product is made of hindered phenol 1076 and phosphite 168, provide excellent production in polyolefinea. The low volatility of the product allows to be uses at relatively high temperatures while providing excellent resistance to extraction from polymer compounds. The blends are active during polymer processing and provide excellent stabilization against thermo-oxidative degradation during long term aging. The BLENDS are used for process stabilization of a wide range of thermoplastic polymers such as polyolefins(PP HDPE LDPE LLDPE), polycarbonates, ABS and polyrsters. The general using rate is 0.03-0.5%.
