COMPOSITION
Compressed sheets for gaskets made of mineral fibres and dispersed inorganic loads in a matrix of rubber. The product BELPA® CSA–25 is suitable for a wide range of applications with low levels of responsibility. This material has low gas permeability and cost, that makes this asbestos-free product suitable for most common uses (air, water, some oil and heavy grease).
Material designed for water, air, gas and general moderated applications, specially for drinking water applications (Institute Pasteur approval for drinking water). It is also available with anti-stick coating. REF. BELPA® CSA-25 G.

P-T OPERATING GUIDELINES
- Usually satisfactory to use without reference to Montero. Technical examination is normally unnecessary.
- Must refer to Montero for advice. A technical examination is recommended.
- Area not recommended.
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.
