Entering mid-to-late March, the upstream market remains calm while the downstream sector witnesses wave after wave of price increases. Affected by the recent geopolitical conflicts between the US and Iran, international crude oil prices have soared sharply. This has rapidly transmitted to the petrochemical industry chain, and many related raw materials in the organic silicon industry chain have also risen accordingly, stimulating silicone sealant enterprises to issue price increase letters intensively, presenting a booming market scene. However, behind this round of price surges, market sentiment towards high-price stockpiling is generally muted. After a general increase of 300 yuan in early March, upstream monomer manufacturers have maintained stable operations, with no clear positive news sufficient to drive a new round of price increases recently. As a result, midstream and downstream enterprises remain cautious in procurement, and market transactions are mostly small orders based on rigid demand. Nevertheless, raw material prices rose first, followed by silicone sealants. Especially under the collective price adjustment of 107 silicone rubber, silicone oil, crosslinking agents, silica and other key raw materials, the long-pressured silicone sealant enterprises can no longer bear the cost pressure.
