Luperox® A75FP pharmaceutical grade benzoyl peroxide is available for shipment anywhere worldwide. A drug master file (DMF) is continuously maintained with the United States Food and Drug Administration, and the product complies with USP and PhEur monograph specifications. Recently, advanced testing allowed Arkema to certify the product under these guidelines for a shelf-life of 2 years. Luperox® A75FP pharmaceutical benzoyl peroxide is a fine free-flowing, water-wet powder with a very tightly controlled particle size dispersion. More information is available upon request!

Luperox® A98 anhydrous benzoyl peroxide powder is a unique product in the world of benzoyl peroxides. Arkema stands alone as the only manufacturer in North America to market benzoyl peroxide with a specified concentration above 98.5% active. In applications such as silicones, hybrid polyurethanes, adhesives, or polystyrenes that require low or zero water content, this dry benzoyl peroxide is very well suited. Luperox® A98 is available in North America only. Anhydrous benzoyl peroxide pastes are available worldwide. Please contact a representative to discuss availablility.

Luperox® AFR40 pourable benzoyl peroxide paste is designed for ease of use in pumping and spraying applications that require the short half life given by benzoyl peroxides. As a diacyl peroxide, benzoyl peroxide formulations are used widely in such applications as vinyl monomer polymerization, unsaturated polyester resins, and crosslinking of elastomers. The new generation of liquid thermoplastic, styrene-free resins (Elium® by Arkema) for composites can also be cured using Luperox® AFR40 pourable benzoyl peroxide paste. The traditional benzoyl peroxide reaction promoters, such as dimethyl aniline or other tertiary amines can be used to achieve room-temperature polymerization.

Luperox® ANS55 hydrous benzoyl peroxide paste is a blend of benzoyl peroxide and n-butyl benzyl phthalate with a proprietary filler. Arkema adapted this technology design to give high performance curing in adhesive and coatings applications where water content is not a chief concern. The active concentration range for Luperox® ANS55 is 55-58%, therefore it can only be shipped in a container not exceeding 40 lbs. net weight.

Luperox® ATC50 is an anhydrous benzoyl peroxide paste useful in acrylic or silicone adhesives, urethanes, polymer concrete, and other applications where a very low water content is desirable. Luperox® ATC50 anhydrous BPO paste is a 50-52% active weight product, with remainder tricresyl phosphate as a plasticizer.

Luperox® LP dilauroyl peroxide is the one of two very fast half-life ambient control temperature peroxides sold by Arkema worldwide (the other being Luperox® A75 benzoyl peroxide powder). Dilauroyl peroxides are useful in PVC production either for suspension or microsuspension processes. While transportation of Luperox® LP dilauroyl peroxide is permitted at ambient temperatures, storage at 40°F is recommended to maintain quality.

Luperox® SAP diacyl peroxides are used in the production of acrylic resins in paints and coatings. They offer a low molecular weight and narrow polydispersities. This allows for high quality, colorless results.
