COMPOSITION
High quality compressed sheets for gaskets made of mineral fibres, aramid and dispersed inorganic loads in a matrix of high quality NBR rubber.
This material has got high compressibility and low gas permeability, excellent characteristics for many industrial services. Material suitable for use with air, water, oils, hydrocarbons and gases. Particularly suitable for use in compressors, and in shipbuilding and hydraulic systems.
It is also available with steel wire reinforcement and anit-stick coating. REF. BELPA® CSA 320 MG.

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.
