Syensqo (Solvay Specialty Polymers) PrimoSpire® PR-9250 Polyphenylene, Self-Reinforced (SRP) (discontinued **)
Categories:	Polymer; Thermoplastic
Material Notes:	PrimoSpire PR-9250 is an injection molding grade of self-reinforced polyphenylene (SRP) that has been tested and found to comply with ISO 10993-1 biocompatibility requirements for limited exposure applications. Articles molded from this resin can be sterilized using all conventional sterilization methods. PrimoSpire SRP is an ultra-high performance amorphous, melt-processable polymer. The unique properties of this material are due primarily to its 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. PrimoSpire SRP has great thermal and thermaloxidative stability, is non-combustible, has higher specific strength than many of the common structural materials and machines easily.
