Domestic Ultra-Clean Foam Silicone Breaks Import Monopoly for
Keywords: semiconductor foam silicone, ultra-clean silicone, wafer cutting cushion, Class 1 clean silicone, domestic substitution
Key Sentence: Self-developed Class 1 clean foam silicone realizes mass supply, cutting chip manufacturers’ raw material cost by over 25%.
High-purity foam silicone specially customized for semiconductor production has achieved full-scale domestic production in June 2026. This silicone material meets Class 1 ultra-clean workshop standards, with ion precipitation controlled below 0.001ppb and strong resistance to acid and alkali etching liquids. It is widely used in wafer cutting suction pads, chip cavity sealing and semiconductor equipment shock absorption components. Previously, this high-end foam silicone relied entirely on imported brands from Japan and Germany. After continuous formula optimization, Chinese silicone manufacturers have matched overseas product performance, and delivered bulk orders to dozens of domestic chip foundries. With the acceleration of semiconductor localization policy, the semiconductor-grade foam silicone segment will maintain a 20%+ annual growth rate in the next three years.
