TORELINA™ polyphenylene sulfide (PPS) polymers offer a unique balance of thermal resistance and chemical resistance that exceed the performance of engineering thermoplastics.  TORELINA™ PPS is available as both linear and branched, with various filler packages, and as optimized blends.  These polymers are suitable for industrial water management components, thermal management including electrical applications, heavy truck, and automotive, as well as food service and other industrial applications.


Polyphenylene Sulfide: Your Polymer Solution for Harsh Environments

The ability to withstand exposure to high heat and humid environments as well as the chemicals that frequently accompany them can pose a performance challenge for many engineering thermoplastics. A loss of dimensional stability and degradation of mechanical properties is common, leading to warpage or breakage of parts, and overall, the inability to deliver the long-term performance required. And in applications in such harsh environments where electrical performance is critical, there is an increased risk of failure.

TORELINA™ Polyphenylene Sulfide (PPS) provides long-term performance for your plastic parts under extreme conditions

When OEMs and designers need a high-performance engineering thermoplastic that can provide long-term heat resistance combined with excellent chemical resistance, they turn to Toray's TORELINA™ polyphenylene sulfide (PPS) polymers. A semicrystalline polymer, TORELINA™ polyphenylene sulfide (PPS) polymers offer a unique balance of thermal resistance and chemical resistance that exceeds the performance of engineering thermoplastics.
