  • Non-asbestos Jointing Sheet Coseal Type 2710
Basis

High-performance composite gasket material engineered with aramid fiber, glass fiber, and rockwool, bonded with a high-viscosity NBR binder for exceptional thermal stability and sealing performance.

Application

Designed for extreme temperature applications ranging from sub-zero to high-temperature environments, offering:
• Superior Fluid Resistance: Excellent performance with steam, water, oils, and hydrocarbons
• Gas Sealing: Exceptionally low permeability for reliable gas containment
• Thermal Versatility: Maintains integrity across wide temperature fluctuations

Area of Application

Suitable – Suitable when chemical compatibility is verified
Conditionally Suitable – Consultation recommended for marginal applications
Not Recommended – Installation prohibited without comprehensive technical assessment
