BUTYL (IIR) COATED ARAMID FABRIC
Fiber consisting of a long chain polymer containing amines and aromatic components. Infusible, does not melt, does not burn, does not soften. Besides it shows low emission of toxic gases while combustion. Certain aramid can decompose at 500° C, It is thermostable up to 250° C.
Butyl, also known as Isobutylene-isoprene (IIR), is a synthetic rubber developed in the 1940’s. It has exceptionally low gas permeability making it ideal for inner tubes and high pressure/vacuum sealing applications. Its very low resilience makes it suitable for shock and vibration damping. Its chemical unsaturation gives it excellent resistance to heat, ozone, and weathering, and also to dilute acids and alkalis.
It is not suitable for use in mineral or petroleum based fluids.
