Headquartered in Philadelphia, the former Organic Peroxides Business Unit operates eleven production facilities worldwide, in the United States, Mexico, Brazil, Germany, Italy, France, India, South Korea and Japan.
Organic peroxides are used as fine chemical intermediates.
The Organic Peroxides Business Unit produces and markets organic peroxides for the following applications.
Polymerization
Luperox® organic peroxides are radical polymerization initiators for commodity polymers such as polystyrene and styrenic copolymers (SAN, ABS, SBR), PVC, low-density polyethylene and acrylics. They act directly on the monomer during polymerization. Some grades of Luperox® are also used to alter the rheology (deformation and flow) of polypropylene to make it more fluid and easier to process.
Curing of Unsaturated Polyester Resins (UPR)
The Luperox® range of unsaturated polyester resin hardeners primarily consists of ketone peroxides, peresters, perketals and benzoyl peroxides.
Luperox® products are used for hot and cold curing of unsaturated polyester resins. In the polyester processing industry, Luperox® organic peroxides are particularly used in the building, transportation and leisure sectors.
Crosslinking (XL)
In crosslinking applications, Luperox® products act on the polymer itself, not the initial monomer. It “builds bridges” between the polymer chains to improve the mechanical properties and heat resistance of the product.
The main market applications in this sector are cable and wire manufacturing and industrial rubber products for the automobile, construction and footwear industries.
