Can Rubber bellows for expansion joint 115 NBR be used with vegetable and animal fats at temperatures up to +90Â°C?

Yes. Rubber bellows for expansion joint 115 NBR Format can be used with vegetable and animal fats at temperatures up to +90Â°C. The product description explicitly states suitability for media including vegetable and animal fats and gives an operating temperature range up to +90Â°C (depending on the medium). Inner layer NBR (nitrile) is compatible with oils and fats, reinforcement is nylon cord, outer layer is CR, and the overall design is intended for installations handling such media. Ensure application-specific validation (pressure, concentration, and exposure duration) but from the given specification the material is appropriate for vegetable and animal fats at temperatures up to +90Â°C.

Are Rubber bellows for expansion joint 115 NBR compatible with aerosol oils and anti-corrosive water additives at -30Â°C to +90Â°C?

Yes. Rubber bellows for expansion joint 115 NBR Format are compatible with aerosol oils and water with added antiâcorrosive substances within the specified temperature range. The inner layer is NBR (suitable for mineral oils, vegetable/animal fats and aerosol oils), reinforcement is nylon cord, outer layer is CR, and the declared operating temperature range is â30Â°C to +90Â°C (depending on the medium), covering the stated conditions.

Is Rubber bellows for expansion joint 115 NBR suitable for use with mineral oils in high-temperature applications?

Rubber bellows for expansion joint 115 NBR Format made with an inner layer of NBR (nitrile rubber), nylon reinforcement and an outer CR (chloroprene) layer are described as suitable for installations where the medium includes mineral oils, vegetable and animal fats, aerosol oils and water with anti-corrosive additives. The stated operating temperature range is â30Â°C to +90Â°C (depending on the medium). Conclusion: Yes. Rubber bellows for expansion joint 115 NBR Format is suitable for use with mineral oils in high-temperature applications up to the specified maximum of +90Â°C. Do note that âhigh-temperatureâ here is limited to +90Â°C per the product specification; for mineral oils at temperatures above +90Â°C, compatibility and performance cannot be guaranteed and an alternative material with a higher temperature rating should be considered. Also verify compatibility with the specific oil type and any additives, and confirm application-specific factors (pressure, dynamic movement, exposure time) with the manufacturer.
