Premium quality compressed sheets for gaskets made of mineral fibre, aramide and dispersed inorganic loads mixed in a matrix of high quality type NBR rubber. BELPA® CSA-520 has the lowest gas permeability value, with the highest tensile strength and the best flexibility.
BELPA® CSA-520 is a high-tech product with the highest stress relaxation value (GRADE X) in the market. Material suitable for many uses and with most of the fluids. TA-LUFT VDI 2440 approval (lowest leakage at 250ºC). Universal gasket material for every equipment and services.
The P-T diagram helps the user or designer who often knows the operating temperature and pressure to carry out an initial selection of a suitable material. The P-T diagram cannot guarantee the suitability of a material for an application.
Good performance and long service life of gaskets depend in large measure on fitting and operation conditions, over which the manufacturer has no control. The data given on this technical sheet should not be used as application limits, but as guidance for an appropriate choice. We can offer guarantees only for the quality of our products.
