Description

Ethyl 3 3-Bis(tert-Amylperoxy)Butyrate is a high-purity organic peroxide, a critical class of compounds used as initiators and cross-linking agents in polymer chemistry. Its primary value lies in its ability to efficiently generate free radicals under controlled thermal conditions, enabling precise polymerization and modification of plastics and elastomers. This product is essential for manufacturers in the polymer, rubber, and specialty chemical industries seeking reliable and consistent performance in their production processes.

Application

• Polymerization Initiator: Used as a free-radical initiator for the production of polyethylene (LDPE), polystyrene, and polyvinyl chloride (PVC).
• Cross-Linking Agent: Facilitates the cross-linking of unsaturated polyester resins and elastomers like silicone rubber and EPDM, enhancing thermal and mechanical properties.
• Curing Agent for Composites: Employed in the curing of fiberglass-reinforced plastics (FRP) and sheet molding compounds (SMC) for automotive and construction parts.
• Organic Synthesis Intermediate: Serves as a specialized oxidizing agent or intermediate in the synthesis of fine chemicals and pharmaceuticals.
• Wire & Cable Coating: Used in the cross-linking of polyethylene insulation for wires and cables to improve heat resistance.
• Adhesive & Sealant Formulation: Acts as a curing agent in certain high-performance anaerobic and acrylic adhesives.
