Silicone-Coated Corrugated Packing is a specialized high-performance sealing material designed to address the demands of high-temperature chemical environments. Combining a corrugated structural design with a silicone coating, it offers superior resistance to extreme temperatures and corrosive chemicals, making it ideal for sealing applications in industries like chemical processing, petrochemicals, and energy production.

Product Composition and Performance Characteristics
The packing features a multi-layered corrugated structure, where each layer is coated with a high-purity silicone compound. This dual design ensures two key advantages: first, the corrugations create a tight, flexible seal by conforming to irregular surfaces, while the silicone coating enhances thermal stability, withstanding continuous temperatures up to 300°C and intermittent peaks beyond 400°C. Chemically, the silicone layer resists degradation from acids, alkalis, solvents, and oxidizing agents, reducing leakage risks in aggressive media like sulfuric acid, caustic soda, and organic solvents. Its low coefficient of friction also minimizes wear, extending service life compared to conventional rubber or metal gaskets.
FAQ:
Q1: What is the maximum continuous operating temperature of Silicone-Coated Corrugated Packing?
A1: Typically 250–300°C, depending on coating thickness and media type; short-term exposure to 400°C is possible.
Q2: Does this packing work with high-pressure chemical systems?
A2: Yes, its corrugated flexibility allows it to maintain sealing integrity under pressures up to 150 psi, common in industrial reactors.
Q3: How does it compare to PTFE gaskets in chemical resistance?
A3: While PTFE excels in some solvents, the silicone coating offers better high-temperature resilience, withstanding 20–30% higher sustained temperatures than standard PTFE.
