Cardboard gaskets,gaskets
18 November 2017

 Composition:

The BELPA CSA-520 gasket sheet is manufactured using the very latest developments in fibres with high thermal and mechanical resistance mixed with a high-quality NBR rubber matrix. The resulting material is a gasket sheet with high mechanical and thermal resistance, very low gas permeability and high residual stress in compliance with BS 7531 GRADE X. BELPA CSA 520 is a gasket sheet suitable for most industrial services, performance at high temperatures making this product the ideal solution for a wide range of services and equipment..

The P-T diagram helps the user or engineer familiar with the conditions of service (pressure and temperature) to select the appropriate gasket material. The diagram does not guarantee the functioning of a material
for an application.
