Superiority

[use 1]
used as an analytical reagent, oxidizing agent, bleaching agent and plastic polymerization initiator
[use 2]
it is used as a monomer polymerization initiator for polyvinyl chloride, unsaturated polyesters, polyacrylates, etc. it can also be used as a crosslinking agent for polyethylene and as a rubber vulcanizing agent.
[use three]
used as a curing agent for unsaturated polyester resins
[use four]
wheat flour whitening agent; oxidizing agent; bleaching agent.
[use five]
as a flour quality improver, it has a bactericidal effect and a strong oxidation effect, which can bleach the flour. china's regulations are only for wheat flour, the maximum use of 0.06g / kg.
[use six]
japanese benzoyl peroxide products, in addition to the purity of 98.0% powder type, there are a variety of commercial specifications, such as paste type (50% of this product and plasticizer 50%), liquid type (75% of this product and water 25%), flour ripening bleaching type (19% to 22% of this product is diluted with one or more of alum, calcium phosphate, calcium sulfate, calcium carbonate, carbonic acid or flour).
the powder type product is mainly used as a polymerization initiating catalyst for an acrylic resin, an mma resin or the like. in recent years, it has been promoted as a fast adhesive for highway engineering and other aspects, and paste products are used as curing catalysts for polyester resin molding processing. the liquid form is used as a polymerization catalyst for preparing a polystyrene resin.
this product is a strong oxidant, sensitive to impact and friction, and the risk of explosion is great. avoid contact with metal powder, activated carbon and reducing agent. water must be used as a stabilizer when storing, the water content is 30%, and the storage temperature is below 30 °c. zhengzhou food additives factory had an explosion accident on june 26, 1993, killing 27 people and injuring 33 people. this product is toxic and can cause inflammation of the skin and mucous membranes. the oral ld50 of mice was 3.949 mg/kg.
[use seven]
mainly used as a polymerization initiator for pvc, polyacrylonitrile and a crosslinking agent for unsaturated polyester and acrylate. used as a crosslinking agent for silicone rubber and fluororubber in the rubber industry. it can also be used as a bleaching agent and oxidant for chemical production.
