Industry Policy: Environmental Supervision Tightens; Small-S
Center Sentence: Local environmental protection and safety inspections have been significantly strengthened recently, focusing on small-scale silicone compound and processing factories with inadequate waste gas, waste water treatment facilities, forcing some enterprises to limit or suspend production, which has tightened regional spot supply and benefited large standardized enterprises.
Keywords: silicone environmental policy, production restriction, silicone industry supervision, small factory shutdown, silicone supply tightening, environmental protection compliance, large silicone enterprises
Detailed Supervision Situation & Industry Impact:
-
Supervision scope and intensity: Since April 10, 2026, environmental protection departments in Shandong, Jiangsu, Zhejiang, and Guangdong (major silicone production and processing regions) have launched a one-month special inspection on the silicone industry, focusing on:
-
Waste gas treatment: Whether the waste gas generated during silicone compounding and processing meets the emission standards (VOCs ≤ 30mg/m³).
-
Waste water treatment: Whether the waste water containing silicone oil and other pollutants is properly treated and discharged.
-
Safety production: Whether the storage and use of flammable and explosive raw materials (such as silicone monomers) meet the safety standards.
-
Inspection results: As of April 13, more than 30 small-scale silicone compound factories and 15 silicone processing factories in Shandong and Zhejiang have been ordered to suspend production for rectification due to inadequate environmental protection facilities; 20 enterprises have been ordered to limit production by 50% until they meet the compliance requirements. These enterprises account for about 8% of the total domestic silicone processing capacity.
-
Impact on supply: The production restriction and shutdown of small-scale enterprises have reduced the effective supply of silicone products in some regions, especially silicone sealants and silicone rubber compounds, supporting the stable operation of mainstream product prices. In East China, the spot supply of some special silicone rubber compounds has become tight, and the quotation has increased by 100–150 yuan/ton.
-
Impact on enterprises:
-
Small and medium-sized enterprises: Face great pressure to rectify environmental protection facilities, with high rectification costs (about 500,000–1 million yuan), and some enterprises may withdraw from the market if they fail to meet the requirements.
-
Large standardized enterprises: Hesheng Silicon Industry, Dongyue Silicone, and other leading enterprises have complete environmental protection and safety facilities, and are not affected by the inspection. They have taken the opportunity to expand market share by increasing production and supplying products to regions with tight supply.
-
Long-term impact: This round of environmental supervision will accelerate the elimination of backward capacity in the silicone industry, promote the concentration of the industry, and guide enterprises to develop in the direction of environmental protection, low-carbon, and high-quality.
