It has a heat resistance temperature equivalent to that of asbestos sheets and is also excellent in corrosion resistance!
"D4000" is a gasket material that has a long-standing high performance record in Europe, where non-asbestos materials have been advanced, and can be used over a wide temperature range from high to extremely low temperatures. Expanded graphite is a material obtained by treating high-purity graphite crystals with chemicals and then heat-treating them at high temperatures. By inserting stainless steel plates (SUS316) into the core material, it becomes a gasket with excellent mechanical strength. 【Features】 ■ Excellent heat resistance and chemical resistance ■ Sealing performance and chemical resistance comparable to asbestos joint sheets ■ Excellent corrosion resistance ■ Wide temperature range from high to extremely low temperatures ■ Excellent compressibility *For more details, please download the PDF or feel free to contact us.
