United Initiators BENOX®B50-55 Diphenylacetyl Peroxide 94-36-0

2023-10-11benoxb50-55
Description: BENOX® B-50 and B-55 are finely dispersed dibenzoyl peroxides that come in the form of a smooth, non-separating, fire-resistant creamy paste.Their patented (U.S. Patent No. 5,334,326) benzoate plasticizer diluent system provides formulations that dissolve easily in resins and monomers.Compared to dry granules of dibenzoyl peroxide, these products pose fewer hazards and are more convenient to use, provided that the plasticizer and moisture content are not objectionable. Other benefits of the benzoate plasticizer system include better resistance to thermal degradation and the elimination of phthalate plasticizers. Product Variants:
  • BENOX® B-50-106: Creamy, white, non-separating, containing 50% dibenzoyl peroxide, primarily used for automotive body fillers.
  • BENOX® B-50-210: A blue variant containing 50% dibenzoyl peroxide; it is creamy in appearance, does not separate, and is used in automotive body fillers.
  • BENOX® B-50-230: A light blue variant containing 50% dibenzoyl peroxide; it is creamy in texture, does not separate, and is used for automotive body fillers, suitable for customers who prefer a light blue paste.
  • BENOX® B-50-513: A red 50% dibenzoyl peroxide paste, one of the most popular non-separating paste formulations in the B-50 series.
  • BENOX® B-50-713: A 50% diphenylcarbonyl peroxide paste with a halo-like appearance that does not separate, used for automotive body filling.
  • BENOX® B-55-107: A basic white 55% diphenylcarbonyl peroxide paste, primarily used in the rock bolting industry and other sectors requiring further dilution prior to use.
  • BENOX® B-55-108: A white paste containing 55% dibenzoyl peroxide, formulated for room-temperature and heat-curing of unsaturated polyester resins.Compared to the 107 formulation, B-55-108 has a lower moisture content, a creamy consistency, and does not separate.
Technical Data:
  • Dibenzoyl Peroxide Content: B-50 (50%), B-55 (55%)
  • Active Oxygen Content: B-50 (3.3%), B-55 (3.6%)
  • Form: Creamy paste
  • Color: White
  • Solubility: Soluble in oxidizing and aromatic hydrocarbon solvents; slightly soluble in alcohols and petroleum solvents; insoluble in chlorinated solvents
Applications: BENOX® B-50 & B-55 are primarily used as polymerization initiators and curing agents for monomers such as ethylene, propylene, styrene, and unsaturated polyester/vinyl ester resins, as well as copolymers of these resins, provided that plasticizer and moisture content are tolerated.Compared to dry granular products, this product offers the following advantages:
  1. Significantly reduced hazards associated with handling and storage.
  2. The ultrafine particles of dibenzoyl peroxide are uniformly dispersed in plasticizers and dissolve more easily in resins, eliminating the hazardous practice of dissolving dry dibenzoyl peroxide in styrene, acetone, or other volatile solvents.
In addition, the following application areas are mentioned:
  • Room-temperature molding
  • Automotive body filler
  • High-temperature molding
  • Adhesives
