P84® polyimide derived from aromatic dianhydrides and aromatic diisocyanates exhibits outstanding thermal stability. The polymer is non melting, has a glass transition temperature of 315°C. The fibres start to carbonize at temperatures beyond 370 °C. Due to the aromatic structure the polymer and fibres are inherent non flammable. A limiting oxygen index of 38 percent can be measured. P84 can be used to temperatures up to 260 °C depending on the environment.

Fibre Properties
Features of the P84 polyimide fibres are the irregularly lobed cross-section being responsible for the high bulk of the fibres. The typical mechanical fibre data describe that P84 is rather a textile fibre with good knot and loop strength properties. Because of the low modulus and the high elongation P84 polyimide fibres are not destined for typical "reinforcing" applications as p-aramid or carbon fibres.
