Grades of Toray PPS Resin, TORELINA™
The basic grades include the glass fiber reinforced type, which offers high strength and relatively excellent toughness, the glass fiber + filler reinforced type, which offers excellent dimensional accuracy, and the unreinforced type, which is low in strength but sticky. Each grade is available as the cross-linked polymer type, which has excellent creep properties and so on, and the linear polymer type, which offers excellent toughness. There are also other variations such as the high flow type, for which the amounts of reinforcement and polymer molecular weights are adjusted. Also in the lineup are elastomer improvement types, for which the low toughness, a weakness of PPS, is improved. In addition, special purpose grades are also offered, which have high sliding properties, high laser weldability, low levels of chlorine, tracking resistance, and other additional properties. For details, refer to the catalog.

Waterproof x Vibration-less x Short tact time!! What are PBT and PPS resins, suitable for laser welding methods?
Electronic Device Components are increasing in functionality, which creates new challenges for joining the thermoplastic resin components while maintaining high quality and high efficiency. This brochure provides material solutions using PBT and PPS materials, which produce high laser weld strength to deliver stronger, higher quality components while minimizing the impact of heat and stress during the welding process.
Technology advancements in high-performance laser welding resin thermoplasticsUsage and characteristics of laser weldable PBT and PPS
Laser welding of thermoplastics is becoming preferred methods to enhance quality of components manufacturing. Here, we will explain the advancements in PBT and PPS compounds are used for laser welding method including the unique features.
Toray resin technology increases the reliability of electronic device componentsDramatically Improved Bonding Is Achieved Between the PPS Resin and the Sealing Material
Electronic device parts require the use of epoxy resins and silicone resins as sealants for conductor materials. Sufficient bonding between the high-performance thermoplastic resin used for manufacturing the exterior of an electronic component and the resin used for sealing it is extremely important in ensuring the reliability of the component.
Thermal expansion equivalent to that of metalsNew Torelina™ Series of PPS Resins Delivers Superior Dimensional Stability That Minimizes Dimensional Changes Caused by Fluctuations in Ambient Temperature
Resin is a proven alternative to metal. It can be attractive in the application where weight reduction and less post-processing is desirable. A swap can be challenging in certain instances, however, because of the differences in the materials’ thermal expansion properties. Toray proposes the use of its new TORELINA™ PPS resin, manufactured by means of a proprietary formulation technology that has the thermal expansion equivalent of aluminum or copper.
Achieving PPS Resin Tracking Resistance (CTI ranking 0) That Enables Miniaturizationand Space-saving in Automotive Components
Tracking resistance of insulating materials is the key to miniaturization and space -saving in electrical components important for the switch to electric vehicles.We are delighted to show you this innovative new material which is widely used in automotive electrical components. It has achieved a CTI ranking of 0 (600 V) for PPS resin, which was previously thought impossible.
Realizing metal replacements and integrations of pipingSuper-Flexible PPS with the World's Highest Level of Softness
Toray's newly developed super-flexible PPS resin features world-class flexibility, and is suitable for all molding methods. It has the potential to provide new value to customers in a variety of ways, such as by replacing metals in piping, simplifying assembly processes, reducing the number of parts via parts integration, and replacing materials such as fluororesins and thermosetting rubbers.
