Технические характеристики

Приложения

Polymer and Plastics Industry

• Benzoyl Peroxide (BPO) is one of the most widely used radical initiators in polymerization processes. When decomposed by heat or light, it generates benzoyloxy radicals that initiate chain reactions in vinyl monomers such as styrene, vinyl chloride, acrylonitrile, and acrylates. It is particularly important in the manufacture of PVC, PS, PAN, and PMMA through suspension, bulk, and emulsion polymerization systems.
• BPO ensures controlled molecular weight distribution, consistent polymer structure, and high conversion rates. With the shift toward high-transparency and bio-based polymers, it remains a preferred initiator due to its reliable decomposition profile and compatibility with advanced solvent systems. Continuous process innovations, including microreactor and green polymerization technologies, further enhance its efficiency and safety.

Rubber and Elastomer Applications

• In the rubber industry, Benzoyl Peroxide serves as a curing and crosslinking agent for silicone rubber, fluororubber, and other specialty elastomers. During vulcanization, it abstracts hydrogen atoms from polymer chains, forming crosslinked structures that enhance thermal resistance, tensile strength, and elasticity.
• BPO-based curing systems are favored for high-performance rubbers used in automotive seals, aerospace components, and industrial hoses. It is often supplied as a 50% paste formulation in silicone oil to ensure safe handling and uniform dispersion. The growth of electric vehicles and advanced elastomer materials continues to boost demand for high-purity BPO.

Pharmaceutical and Dermatological Uses

• Pharmaceutical-grade Benzoyl Peroxide is an essential topical agent for acne treatment, valued for its antibacterial, anti-inflammatory, and keratolytic effects. It releases nascent oxygen that oxidizes bacterial proteins, effectively killing Cutibacterium acnes and reducing sebum accumulation.
• BPO is available in 2.5%, 5%, and 10% formulations in gels, lotions, and cleansers. It is often combined with clindamycin or adapalene for synergistic acne therapy. Due to its non-antibiotic mechanism, it avoids bacterial resistance—a significant advantage over traditional antibiotics.
• Technological advances such as microencapsulation enhance its stability and minimize irritation, while controlled-release formulations are gaining prominence in dermatological care.

Coatings, Adhesives, and Composite Materials

• Benzoyl Peroxide is a key curing agent and initiator for unsaturated polyester resins (UPR) used in coatings, adhesives, fiberglass, and composite materials. It enables room-temperature polymerization, producing strong, heat-resistant resins for construction, marine, and automotive applications.
• In adhesives, it supports polymer crosslinking for acrylates and vinyl acetate systems, ensuring fast curing and strong bonding. Its compatibility with both solvent-based and waterborne formulations aligns with green chemistry trends promoting low-VOC production.

Textile, Ink, and Bleaching Applications

• In the textile sector, BPO acts as an oxidizing and grafting agent. It is used for fabric bleaching and for initiating graft polymerization of functional monomers onto polyester or wool fabrics, improving dyeability, hydrophilicity, and wrinkle resistance.
• It also finds application in printing inks и polymer coatings due to its rapid curing and high reactivity at moderate temperatures.

Electronic and High-Tech Materials

• High-purity Benzoyl Peroxide is increasingly applied in semiconductor encapsulation, microelectronics, and photoinitiator systems. It ensures low impurity levels and stable decomposition, suitable for precision molding and insulation materials.
• In the renewable energy and electronics sectors, it contributes to curing epoxy and polyester resins for wind turbine blades, PCB laminates, and encapsulants used in solar and LED devices.

Environmental and Emerging Applications

• Beyond traditional uses, BPO is gaining traction in green polymerization, bio-based materials, and wastewater treatment. It serves as an oxidant in dye degradation and a catalyst in advanced oxidation processes. In bio-material synthesis, it promotes chain growth in biodegradable polymers and enhances recyclability in polymer modification.
