China's Toughener Market Booms with Domestic Technological Breakthroughs

According to the 2024 Global Toughener Industry Whitepaper, China’s toughener market is growing at a CAGR of 7.2%, expected to surpass ¥45 billion ($6.3 billion) by 2025. SBS (styrene-butadiene-styrene) and POE-g-MAH (maleic anhydride-grafted polyolefin elastomer) tougheners dominate over 60% of applications in automotive bumpers and appliance housings. Recently, domestic manufacturers have broken foreign monopolies in new energy vehicle (NEV) battery casing materials by developing high-temperature-resistant tougheners (withstand -40°C to 150°C) through nano-dispersion and core-shell structure technologies.

Industry analysts predict that lightweighting and high-impact resistance demands will drive toughener adoption in emerging sectors like photovoltaic brackets and drone components, with penetration rates reaching 25% in the next five years.
