■Basic physical properties
■ Precautions for use 1) Fluids for which a fluoropolymer gasket is not suitable. ・ Do not use a PTFE gasket with molten alkali metal, high-temperature fluorine, chlorine trifluoride or other fluid that corrodes PTFE. ・ When a fluororesin gasket is used with a monomer-based fluid, the fluid may permeate into the gasket, resulting in polymerization. In such a case, it is recommended that you either replace the gasket at shorter intervals, or use a VORTEX gasket.
2) Gas-type fluid When using a fluoropolymer gasket to seal gas, use TOMBO No.9400 (NAFLON paste) together in order to improve the sealing performance.
NICHIAS Corporation was founded in 1896 as a pioneer in thermal insulation materials. For more than a century, NICHIAS has achieved growth by Insulation and Protection technologies which consist of six core elemental technologies that include sealing, thermal insulation, soundproofing, fire-resistant, anti-corrosion as well as clean. These six technologies help protect our natural environment. For example, insulation technologies help reduce CO2 emissions and are energy efficient, while sealing technologies prevent environmental pollution.
