1.
Core Innovation: Self-developed gradient temperature-controlled phase-transfer catalytic polymerization technology bypasses overseas patent barriers and eliminates traditional high-side-reaction emulsion polymerization. The polymer molecular weight distribution index (PDI) is reduced from the industry standard 1.9–2.2 to ≤1.4; chlorine content is stably locked at 60.3±0.4%. Free chlorine drops from 0.3% to below 0.05%, and total heavy metal ion content in the resin ≤8 ppb, meeting SEMI F57 standards for electronic semiconductor materials. Wanhua is China’s first chlorinated ether resin manufacturer certified SGS electronic grade. The fully halogen-free synthetic process eliminates carbon tetrachloride halogenated solvents during production.
