High performance asbestos free fibre materials SPETOBAR^® BAS^®300, BAS^®340

SPETOBAR^®BAS^®340I is the sheet manufactured from the same fibre-elastomeric mix as SPETOBAR^®BAS^®340; the-refore it has similar properties as per chemical resistance, resilience, physiological safety, resistance to ageing etc.; it is, however, equipped with 0,5 mm thick, mesh 1.4404 stainless steel reinforcement, this reinforcement increases ten-sile strength, resistance to stress and resilience, also makes the gasket more rigid which is important during the in-stallation;thanks to the reinforcement, the material can withstand higher pressure and/or temperature loads which is important in hot water or steam service; also reinforcement does not have negative influence on permeabilty, due to the special technological process; BAS 340I is used in chemical industry, refineries, power plants, coke plants, in all places where substantial pressure and temperature loads occur and where the flange faces are narrow, BAS^®340I has a non-stick top and bottom layer of high coefficient of friction; in special version – when used in components which rotate on te gasket during assembly, a graphite coating on one or both sides of the gasket is required.

SPETOBAR^®BAS^®340 is a non-asbestos sheet or a gasket based on aramid firbres, non-organic fillers with high quality elastomer as a binder, manufactured in a multi-stage calendering process, has mechanical and temperature characteristics distingishing it from other fibre materials; it is physiologically safe, without any pigments, exhibits excellent tensile strength, shearing and stress resistance; in service with gas and liquids, e.g. oils, fuels, freons, liquid gases, solvents, hot water and steam but without pressure and temperature fluctuations1); easy to handle, exhibits outstanding chemical resistance and ability to work in high pressures; Surface treatment: as standard, SPETOBAR^®BAS^®340 is coated with a non-stick agent of high coefficient of friction (stabilizes the gasket in the joint), therefore no further steps to improve surface characteristics are necessary; only in situations where relative movement is the case, sheet (gasket) may be delivered with graphited surface on one or both sides; BAS^®340 is one of the very few fibre materials that are fire-safe (BS 6755); may be exposed to oxygen, food, gas, potable water etc.

SPETOBAR^®BAS^®300 is a material based on aramid firbres and other non-asbestos fillers bonded by mix of high quality elastomers in the special calendring process; the material has good forming properties, low permeability, good mechanical properties and withstands high temperatures; it can be applied as a “universal” sealing solutions within the range of medium temperature and mechanical loads; material can work in services with exposure to oxygen; as standard, BAS^®300 has anti-adhesion surfaces of high coefficient of friction; used in hydraulic, cooling systems (containing freon and based on water cooling agents), water solutions, fuels, solvents, de-freezing agents, alkalis.
