Chemical resistance
The fully imidized nature of P84 yields excellent chemical resistance to various solvents, acids, and hydraulic fluids. P84 polyimide is produced using novel isocyanate technology which yields a unique, fully imidized material without the need for curing. Other polyimides must be moulded and cured. The curing closes the imide rings and produces water as a by-product that migrates out through the surface. Fabricated parts made from TECAPOWDER P84 are non-porous, which minimises the migration of fluids into the surface layers and greatly improves chemical resistance.
