Customizable size/color silicone rubber sheet/silicone seal/silicone processing parts
1.Product Introduction
 |
This industrial silicone rubber sheet is vulcanized with high-purity fumed/precipitated silicone raw materials, a high-performance elastic sealing slab. It owns stable physical and chemical properties, long-term service under extreme high & low temperature. Resist UV, ozone, acid & alkali corrosion, with outstanding insulation, shock absorption, sealing and waterproof performance.
Widely applied in machinery, electronics & electrical, new energy, chemical pipeline, high-temp oven, heat transfer printing and other industrial fields. Support custom cutting & die-cutting. Modified versions including flame retardant, conductive, fiberglass reinforced, food contact grade are available. Direct supply from factory, sufficient stock, bulk export supported. |
2.Core Advantages
