The addition of organic peroxides to the molten polypropylene during extrusion is called vis-breaking or controlled rheology of polypropylene (CRPP).
Main organic peroxides developped by Arkema under the trade name Luperox^® to be used are: di-tert-butyl peroxide, di-amyl-butyl peroxide and 2,5-dimethyl-2,5di(tert-butylperoxyl)-hexane.

Arkema provides a wide range of Luperox^®, Retic^®, Vul-Cup^®, or Di-Cup^® Bis-peroxide and DCP formulations that are can be extruded or injection molded the elastomer to achieve crosslinked rubber products in food grade or industrial applications. 

The initiator plays a dominant role in the free radical synthesis of acrylic-based coating resins. Arkema offers a wide range of organic peroxide initiator under the trade name Luperox^® and helps to proper selection to ensure production of acrylic coatings with a focus on acrylic high-solid coatings (HSC) resins with low molecular weight, narrow polydispersity, low viscosity and reduced volatiles.

Arkema offers a large range of organic peroxide initiators under the trade name Luperox^® suitable for the different polystyrene technologies, such as General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) continuous mass processes and expandable polystyrene (EPS) batch suspension process to make a wide variety of consumer products.

Arkema offers a large range of organic peroxide under the trade names Luperox^®, Retic^®, Vul-Cup^® or Di-Cup^® used as a cross-linking agent in semiconductor-layers of medium to high voltage cables. Organic peroxides can also be 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.

Arkema manufactures a wide range of organic peroxides for Ethylene-Vinyl Acetate (EVA) production under the trade name Luperox^®. Arkema keeps on developing new products and services, such as higher conversion rate, lower global specific consumption, or safety standard during operation.

Photovoltaic (PV) panels are made by laminating components (glasses, cells, back sheets, etc.) with encapsulation films. Arkema offers a wide range of Luperox^® organic peroxides for the crosslinking of the EVA/POE encapsulation films and keeps on developing new products and services.
