PrimoSpire PR-351 resin is a high fluidity injection molding grade PrimoSpire self-reinforced polystyrene (SRP). PrimoSpire SRP resin is an ultra-high performance amorphous, melt-processable thermoplastic. The unique properties of this material are mainly derived from its rigid rod-like chemical structure. PrimoSpire difference from other thermoplastics is that they have excellent mechanical properties without fiber reinforcement. In addition, it also has scratch resistance, excellent friction and wear resistance, excellent solvent resistance and excellent low temperature performance. In addition, PrimoSpire SRP also has good thermal stability, non-flammability, higher specific strength than materials used in many common structural components, and excellent machining performance. PrimoSpire SRP's excellent mechanical, chemical, thermal and physical properties make it the material of choice for various products, such as aircraft sub-structures, semiconductor components, bushings, bearings and gears, light vehicle suspension systems, medical pipes and other equipment. -black: PR-351 BK 931 |
