Pinanyl hydroperoxide

Pinanyl hydroperoxide (CAS 28324-52-9), also known as Pinane hydroperoxide, is an organic peroxide used as a radical source in polymer manufacturing and curing systems.

Where is Pinanyl hydroperoxide used?

• Rubber and tire manufacturing: polymerization initiator for emulsion and solution polymerization of synthetic rubbers, including SBR and other diene-based elastomers
• Coatings: redox initiator systems for low-temperature cure initiation, enabling film formation where thermal initiators are ineffective
• Adhesives and sealants: supports cross-linking and curing of elastomeric bases, contributing to bond strength and heat resistance
• Plastics processors employ it to initiate controlled radical polymerization in specialty resin systems.

Good to know: Buyers should confirm active-oxygen content and concentration specifications directly with suppliers, as these vary across producers and determine initiator efficiency in process design. Proper storage and handling are critical for maintaining product stability.

Commercial specifications

• Derived from the oxidation of pinane
• Active-oxygen content and concentration specifications vary across producers
