Vul-Cup® R, Luperox® F, 101, and DCP organic peroxides are a few of the organic peroxides used for crosslinking of automotive rubber parts including hoses, belts, weather stripping, gaskets and seals. It provides the high temperature resistance needed in today's engines that cannot be obtained with regular sulfur cured compounds.
Retic® BP 50 LA pastes of benzoyl peroxides, available in different colors, are used at room temperature with polyester putties to repair dents and irregularities in car bodies. A wide range of packaging is available from the smallest tubes or jars to 25kg pails. The product is in a phthalate free solvent.
Luperox® 26, DTA, and DI organic peroxides are some of the key organic peroxides that offer a range of benefits to acrylic coatings. Promoting high monomer conversion with low residuals, organic peroxides contribute to resin performance while keeping molecular weight and viscosity manageable in today’s low VOC formulations.
Luperox® F / Vul-Cup® R and Luperox® 101 organic peroxides improve the melt flow rheology of polypropylene giving it properties that benefit packaging for consumer products, plastic automotive parts, and non-woven textiles. Easy to handle formulated grades with lower peroxide concentration such as Luperox® 101PP7.5, F20ED, F10ED, etc. are preferably used to homogenize and increase the melt flow properties of PP during the recycling process.
Luperox® A75, TBEC & TAEC organic peroxides are used as polymerization initiators to make expanded polystyrene (EPS). EPS is a lightweight and cost-effective polymer that provides temperature control in applications such as hot beverage containers, food packaging, goods cushioning and housing insulation.
Composites for Windmill blades
Luperox® MEKP organic peroxide is used for the curing of unsaturated polyester resin (UPR) used to manufacture windmill blades. Luperox® A75 organic peroxide is also used to manufacture Elium® - Arkema's specialty liquid thermoplastic resin for composites used in the manufacturing of strong and durable windmill blades.
EVA shoe soles
Luperox® F/ Vul-Cup® R organic peroxide is used in shoe soles made from EVA foaming to create a cross-linking net for improved mechanical strength. The applications include sports shoes, slippers and sandals, especially for kids. Compared with dicumyl peroxide, Luperox® F/ Vul-Cup® R is odorless.
Luperox® MEKP organic peroxide is used in a variety of composite applications for the residential building market. Those applications include fiberglass tub and shower units for both residential and hospitality, cultured marble for vanity and shower pans as well as tub and shower surrounds.
Luperox® F/ Vul-Cup® R, Luperox® 231 organic peroxides are used as cross-linking agents in rubber building profiles and sponge door profiles. Compared to sulfur curing, Luperox® peroxides impart higher durability thanks to better compression set and heat ageing resistance. With Luperox® AIR® organic peroxide technology, curing performances can be obtained with a simple hot air tunnel system.
EVA/POE Encapsulant for Solar Panel
Luperox® TBEC-H, TCS, TBEC and other Luperox® organic peroxides are used for crosslinking EVA/POE encapsulation films. Photovoltaic (PV) panels are made by laminating components (glasses, cells, back sheets, etc.) with encapsulation films. These films are also used to manufacture safety glasses.
Luperox® 223, 610, LP and 10 organic peroxides are key in processes used to make polyvinyl chloride (PVC). PVC is a versatile thermoplastic polymer used to manufacture products ranging from piping and siding, blood bags and tubing, wire and cable insulation, automotive components, pool liners and many more.
Low voltage cables
Luperox® F/ Vul-Cup® R organic peroxide is used as cross-linking agent for Chlorinated Polyethylene (CPE) and Ethylene Propylene diene monomer (EPDM) to improve mechanical performance, chemical resistance and electrical properties. CPE and EPDM are used in low voltage cable jacket layers, especially for home appliances that require very low odor level.
Low density Polyethylene (LDPE)
Luperox® 223, 10, 26, 11, DI, & 7M50 organic peroxides are some of the key organic peroxides used as polymerization initiators in the manufacturing of low-density polyethylene (LDPE). In addition to securing packaging for transport, LDPE plastic wrap provides the protective barrier necessary to keep perishable food fresh and healthy.
A wide variety of products
Through its worldwide presence, our group offers highly customer-oriented services including:
- Reliable and customized logistics
- Safe storage and handling practices
- Technical support for process optimization
Through our advanced Organic Peroxide R&D centers and safety experts in Changshu (China), in King of Prussia (PA - USA) and in Lyon (France), Arkema assures local safety services and the development of new applications for growing and innovative products by offering a comprehensive range of organic peroxide market solutions:
Plastic manufacturers use a wide range of organic peroxides as polymerization initiators for synthesizing key thermoplastic polymers such as Polyvinyl chloride, Polystyrene, LDPE(Low Density Polyethylene), EVA (Ethylene-Vinyl Acetate Copolymer), Polymethyl methacrylate, etc.
The oxygen bond in organic peroxides is easily reacted by thermal energy releasing free radicals that can serve as an initiator for the free radical polymerization reaction. In polypropylene (PP) modification the free radicals released by decomposing organic peroxides lead to degradation of PP called vis-breaking. The result is modification to the melt flow index of PP.
Unsaturated polyester resin composites are found in marine, RV, kitchen and bath, pipe repair, structural adhesives or engineered stone countertops, just to list few applications. Arkema provides organic peroxides, which are used to initiate the curing process mainly for UPR and acrylic resins.
Our products are essential ingredients to make composites for a range of manufacturing processes such as SMC, BMC, pultrusion, resin transfer molding, spray up, artificial solid surface, etc. Let us know your requirements, we have the organic peroxides you need.
High-performance demanding industries such as automotive, power cables, and oil and gas use organic peroxide cross-linked polymers due to their superior mechanical properties, improved high temperature resistance and heat aging characteristics. They also participate in manufacturing of high performance/ cost effective foams for sports & leisure industry.
At Arkema, we help industries like yours with organic peroxides widely used as crosslinking agents for a wide range of polymers and elastomers such as EPDM, silicone rubber, natural rubber, EVA and others.
The versatility of organic peroxide with plastics provide innovative solutions in the development of renewable energy, especially solar energy and wind energy. Organic peroxides provide fast curing of EVA/POE used to encapsulate PV cells.
The fast cure decreases production cycles and lowers the cost of PV panel production. Similarly, our organic peroxides are used for the curing of UPR resin used in the manufacturing of strong and durable windmill blades.
