Luperox® 231 by Arkema is 1,1-di(t-butylperoxy)-3,3,5-trimethylcyclohexane. Acts as a crosslinking agent. It is a colorless liquid (92%) and is available in several concentrations from 50% to 90% with organic solvent and as a technically pure liquid. Luperox® 231 is used in polymerization in bulk, solution, suspension, polymer modification, curing elastomers, polyester and acrylic syrup. Luperox® DCP by Arkema acts as a polymerization initiator, vulcanizing and crosslinking agent. It is dicumyl peroxide (DCP). It is compatible with thermoplastic elastomer vulcanizates, polypropylene and expandable polystyrene.<br> <ul style="padding-left: 40px;"><li> It is suitable for use as finisher and as synergist for fire retardant EPS applications.</li> <li> Luperox® DCP can be processed at temperatures up to 250°F (121°C) and can be cured at temperatures above 300°F (149°C).</li> <li> It is recommended for general & renewable energy applications such as wire and cable.</li> </ul> Luperox® K1SN by Arkema is methyl ethyl ketone peroxide. It is recommended for the cure of unsaturated polyester resins at room temperatures in combination with a cobalt accelerator. It is used for applications such as hand lay-up, spray up, centrifugal casting, filament winding, polyester concrete, etc. Luperox® K1SN is particularly suitable for gel coat curing. Its low viscosity makes it ideal for spray-up techniques (airless) with external mixing. Faster reaction with shorter demold times can be obtained by the addition of promoters such as dimethyl aniline. Luperox® Z390 by Arkema is a peroxide blend. It is used for the cure of unsaturated polyester resins in combination with a cobalt accelerator. It allows extremely fast curing at either room or elevated temperatures, which means shorter cycle times and as a consequence, higher productivity. Luperox® Z390 formulation guarantees much better curing than normal acetyl acetone peroxide this results in low residual styrene and tack-free surface GRP articles. Luperox® Z33G by Arkema is a phthalate-free blend of two ketone peroxides (MEKP and AAP). It is used for the cure of unsaturated polyester resins at room temperature in combination with a cobalt accelerator. Luperox® Z33G gives faster curing and higher peak temperatures than methyl ethyl ketone peroxides (MEKP) at either elevated or room (40-80°C) temperatures when in association with a cobalt accelerator. Luperox® TAH75 by Arkema is an 85% aqueous solution of tert-amyl hydroperoxide. It can be used alone or in combination with other organic peroxides in solvent and emulsion polymerizations of acrylics resins. Luperox® TAH75 is soluble enough in water to be used in waterborn resins. Luperox® Z11G by Arkema is a phthalate free blend of two ketone peroxides (MEKP and AAP). It is used for the cure of unsaturated polyester resins at room temperature in combination with a cobalt accelerator. Luperox® Z11G gives faster curing and higher peak temperatures than methyl ethyl ketone peroxides (MEKP) at either room or elevated (40-80°C) when associated with a cobalt accelerator. Luperox® DP40 by Arkema is ketone peroxide. It is used for the hot curing of unsaturated polyester resin in combination with a cobalt accelerator. It is suitable for curing in the range of 60°C-100°C when used alone. Also, Luperox® DP40 can be used in association with ketone peroxides to achieve a higher degree of curing. Luperox® TAH85 by Arkema is an 85% aqueous solution of tert-amyl hydroperoxide. It can be used alone or in combination with other organic peroxides in solvent and emulsion polymerizations of acrylics resins. Luperox® TAH85 is soluble enough in water to be used in waterborne resins. Luperox® A75FP by Arkema is a free-flowing, white fine powder of dibenzoylperoxide at 73-77%. It is composed only of fine particles of wet solid. Luperox® A75FP used in pharmaceutical applications such as anti-acne formulations.
