PrimoSpire (SRP : Self-reinforced polyphenylene)

PrimoSpire® self-reinforced polyphenylene (SRP) is one of the stiffest and strongest unreinforced plastics in the world.

Even without fiber reinforcement, PrimoSpire® SRP delivers tensile properties that are comparable to those of many reinforced plastics. Plus, you get the added benefits of lighter weight and no loss of ductility.

These properties combine with high compressive strength – one of the highest among plastics – to make PrimoSpire® SRP an excellent candidate for weight-sensitive applications that have historically relied on composites and specialty metals for superior mechanical performance.
