Product Description
PrimoSpire PR-351 resin is a higher flow, injection molding grade of PrimoSpire self-reinforced polyphenylene (SRP). PrimoSpire SRP resin is an ultra-high performance amorphous, melt-processable thermoplastic. The unique properties of this material are due primarily to the rigid-rod chemical structure. PrimoSpire SRP is differentiated from other thermoplastics by outstanding mechanical properties without fiber reinforcement. In addition, it offers scratch resistance, great friction and wear properties, excellent solvent resistance and exceptional low temperature performance.

In addition, PrimoSpire SRP has great thermal stability, is noncombustible, presents higher specific strengths than many of the materials commonly encountered in structural applications, and also possesses excellent machinability.

The outstanding mechanical, chemical resistance, thermal and physical properties of PrimoSpire SRP make it the material of choice for a variety of applications including aircraft substructures, semiconductor components, bushings, bearings and gears, light-weight vehicle suspensions systems and medical tubing and other devices.
