Description

tert-Amylperoxy 2-Ethylhexyl Carbonate is a high-purity organic peroxide used as a free-radical initiator in polymerization processes. Its controlled decomposition characteristics make it a critical component for achieving specific polymer properties and reaction kinetics. This product is essential for manufacturers in the polymer and plastics industries, particularly for the production of PVC, unsaturated polyester resins, and various specialty polymers requiring precise curing and cross-linking.

Application

• Primary Initiator for PVC Polymerization: Used in the suspension and mass polymerization of vinyl chloride to produce PVC resins with controlled molecular weight and particle size.
• Curing Agent for Unsaturated Polyester Resins (UPR): Facilitates the cross-linking of resins in fiberglass-reinforced plastics (FRP), sheet molding compounds (SMC), and bulk molding compounds (BMC).
• Cross-linking Agent for Elastomers and Rubbers: Employed in the vulcanization process to enhance the thermal and mechanical properties of synthetic rubbers.
• Modifier for Acrylic Resins: Used in the production of acrylic sheets, coatings, and adhesives to control polymerization rate and final product clarity.
• Synthesis of Specialty Polymers: Serves as an initiator in the manufacture of high-performance engineering plastics and block copolymers.
• Controlled Radical Polymerization (CRP): Applicable in advanced polymerization techniques for creating polymers with precise architecture.
