Organic Peroxides

Used as Free Radical Initiators, Peroxide Curing Agents & Crosslinking Peroxides

LAAP started its production of organic peroxide compounds in 1966 with a focus on low-density polyethylene catalysts. Over the years, we've developed a complete portfolio of organic hydroperoxides, ketone peroxides, alkyl peroxides, acyl peroxides, and ester peroxides — used as free radical initiators, peroxide curing agents, and crosslinking peroxides for peroxide vulcanization.

Initiator

Free radical initiator for the production of thermoplastics like PE, PVC, and EPS

Curing Agent

Peroxide curing agent for thermoset resins such as polyester and vinylester

Crosslinking Agent

Crosslinking peroxide agent for peroxide vulcanization of elastomers and thermoplastics

Polymerization

of monomers with organic peroxide initiators

Our products include a wide range of organic peroxide initiators and free radical initiators, which are widely used as polymerization initiators in the production of key thermoplastics like PVC, LDPE, and EPS, as well as PS, EVA, ABS, and acrylic resins. These organic peroxide compounds serve as essential initiators, improving the efficiency and performance of manufacturing products like window profiles, pipes, food containers, automotive parts, toys, cosmetic bottles, paints, textiles, and leather.

Key Applications

Low-Density Polyethylene Ethylene Vinyl Acetate Polyvinyl Chloride Polystyrene Polystyrene Polypropylene Polyvinyl Alcohol Acrylic Resin Unsaturated Polyester Resin Pharmaceutical Intermediate Acrylonitrile Butadiene Styrene Polyolefin Plastomer

Curing

of unsaturated polyester, vinylester and acrylic resins with peroxide curing agents

Our organic peroxides are used as peroxide curing agents for unsaturated resins. These peroxide compounds are applied in the manufacturing of fiberglass, artificial quartz stone, and BMC/SMC, which are used in construction, home renovation, anti-corrosion, automotive, and electronics sectors.

Key Applications

Low-Density Polyethylene Ethylene Vinyl Acetate Polyvinyl Chloride Polystyrene Polystyrene Polyvinyl Alcohol Acrylic Resin Unsaturated Polyester Resin Pharmaceutical Intermediate Acrylonitrile Butadiene Styrene Polyolefin Plastomer

Crosslinking

of rubber and polyolefines with crosslinking peroxides

Our crosslinking peroxide agents are utilized in peroxide vulcanization and crosslinking of silicone rubber, EVA, POE, and SBR, which are important for industries such as solar power, medical care, automotive, electronics, building materials, adhesive tapes, and wire and cable manufacturing.
