PrimoSpire® PR-250 BK 931

PrimoSpire® PR-250 BK 931 by Solvay is a black colored, ultra-high performance, amorphous, self-reinforced polyphenylene (SRP) polymer. It is a non-combustible, melt-processable, flame retardant grade. The unique properties of this material are primarily due to the inherent rigid-rod structure. It is suitable for processing by compression molding, injection molding, profile-, film-, wire & cable extrusion and machining. It shows very low coefficient of linear thermal expansion (CLTE), very low moisture absorption, exceptional low temperature performance, high thermal stability, ductility, high stiffness, high strength, exceptional hardness and surface finish. It offers good resistance towards scratch, solvent and chemical. PrimoSpire® PR-250 BK 931 is used in aircraft substructures, semiconductor components, bushings, bearings, gears, films, housings, light-weight vehicle suspensions systems and healthcare/ medical devices and tubing. It complies with RoHS.
