Syensqo (Solvay Specialty Polymers) PrimoSpire® PR-250 Polyphenylene, Self-Reinforced (SRP) (discontinued **)
Categories:	Polymer; Thermoplastic
Material Notes:	PrimoSpire® PR-250 resin is an injection molding grade of self-reinforced polyphenylene (SRP). PrimoSpire® SRP is an ultra-high performance amorphous, melt-processable polymer. The unique properties of this material are due primarily to the inherent rigid-rod structure. PrimoSpire® SRP is differentiated from other thermoplastics by outstanding mechanical properties without fiber reinforcement, scratch resistance, excellent solvent resistance and exceptional low temperature performance. In addition, PrimoSpire® SRP has great thermal stability, is non-combustible, has higher specific strength than many of the common structural materials and machines easily. Features: Ductile; Flame Retardant; Good Chemical Resistance; High Stiffness; High Strength; Scratch Resistant Uses: Aircraft Applications; Connectors; Electrical/Electronic Applications; Film; Gears; Housings; Medical/Healthcare Applications; Semiconductor Molding Compounds Information provided by Solvay Specialty Polymers.
