Product Description: BENOX? C-50 is a white, free-flowing granular powder containing benzoyl peroxide, 50%, and phthalate plasticizers. It is used as a hardener for unsaturated polyester and acrylic resins in both high temperature curing and ambient temperature curing (with amine accelerators) processes. Technical Data: Benzoyl peroxide content is 50%, reactive oxygen content is 3.30%. Appears as a white, free flowing powder with a "start-up" temperature of 70°C. The half-life temperature (in 0.1 moles of benzene) is 72°C. Recommended storage temperature is not more than 30°C. Soluble in phthalates and insoluble in water. Recommended storage temperature not exceeding 30°C, soluble in phthalates, insoluble in water. From delivery

DESCRIPTION: BENOX? B-50 and B-55 are fine dispersions of dibenzoyl peroxide in the form of smooth, non-separating, refractory cream pastes. Their patented (U.S. Patent No. 5,334,326) benzoate plasticizer diluent system provides product formulations that dissolve easily in resins and monomers. These products are less hazardous and easier to use than the dry granular form of dibenzoyl peroxide, provided the plasticizer and moisture content are not objectionable. Other benefits of benzoate plasticizer systems include better dispersion for heat degradation resistance and elimination of phthalate plasticizers. Product Variant: BENOX? B-50-106: Milk
