응용 프로그램

Rubber Industry

• Di-tert-butyl Peroxide (DTBP) is one of the most widely used crosslinking agents in the rubber industry, especially suitable for high-temperature vulcanization systems.
• In EPDM rubber, DTBP decomposes at 140–160 °C to generate tert-butoxy radicals that abstract hydrogen atoms from polymer chains, forming carbon–carbon crosslinks. This reaction significantly enhances tensile strength, thermal resistance, and aging stability. EPDM vulcanized with DTBP exhibits tensile strength of up to 15 MPa and retains elasticity after prolonged exposure to 130 °C.
• For silicone rubber, DTBP provides uniform vulcanization, low residue (< 0.1%), and odorless decomposition products such as tert-butanol and acetone, making it compliant with FDA food-contact standards. Compared with benzoyl peroxide, DTBP minimizes mold corrosion and extends mold life by more than 30%.
• In fluoroelastomer (FKM) and butyl rubber (IIR) systems, DTBP offers excellent compatibility with co-agents like TAIC, improving oil resistance, gas impermeability, and thermal stability for advanced sealing applications.

Plastics Industry

• DTBP is a key crosslinking and modification agent in the plastics sector, accounting for nearly 30% of total consumption.
• In polyethylene (PE), it enables the production of crosslinked polyethylene (XLPE) used in high-voltage cables and heat-resistant pipes. Under extrusion at 180–200 °C, DTBP (0.8–1.2%) forms three-dimensional polymer networks, enhancing temperature endurance from 70 °C to 125 °C and increasing dielectric strength to 35 kV/mm.
• In polypropylene (PP), DTBP acts as both a degradation and crosslinking initiator. At low dosage (0.05–0.1%), it controls melt flow rate (MFR = 15 g/10 min), improving processability. When combined with maleic anhydride, it enhances PP foam elasticity and rebound, doubling the expansion ratio.
• DTBP is also used as an initiator in styrenic polymerization, where its decomposition temperature (126 °C for a 10 h half-life) perfectly matches polymerization temperatures of PS and ABS, offering high conversion (up to 98%) and low impurity levels.

Diesel Industry

• DTBP serves as an efficient cetane number improver in diesel fuel formulations. During combustion, it decomposes at 250–300 °C, producing radicals that accelerate ignition and reduce ignition delay.
• A small addition (0.1–0.5%) raises cetane number (CN) from 35 to 45–55, outperforming traditional nitrate-based improvers while avoiding engine corrosion. The cost-effectiveness and safety profile make DTBP ideal for blending Euro VI–standard diesel fuels.
• Refining companies in China, India, and Southeast Asia use DTBP in large-scale blending, accounting for over 50% of China’s total cetane improver market.

Electronic and Semiconductor Applications

• High-purity DTBP (≥ 99.9%) is used as a crosslinking agent in epoxy encapsulation for semiconductor materials. Its decomposition products are non-corrosive and volatile, ensuring minimal residue and metal contamination (< 10 ppb).
• It enhances glass transition temperature (Tg) of epoxy systems up to 180 °C, meeting automotive and high-reliability semiconductor packaging standards. DTBP’s adoption in chip underfill, copper-clad laminates, and semiconductor sealing materials continues to expand, especially as domestic electronic-grade production grows.

Environmental and Energy Applications

• DTBP plays a role in new energy and green materials. It is used in lithium battery separators to crosslink PP films, improving dimensional stability and reducing heat shrinkage from 15% to 3%.
• In photovoltaic backsheet production, DTBP replaces DCP for PET crosslinking, offering improved UV resistance and low yellowing (ΔYI < 2 after 1000 h exposure).
• In biodegradable polymer modification, DTBP enhances the mechanical strength of PLA and PBAT by chain extension, promoting the transition toward sustainable plastics.
• Its use in recycled PP modification repairs chain scission, restoring tensile strength up to 90% of virgin material—making DTBP essential in circular polymer economies.
