TORELINA™ PPS resin

PPS resin is a thermoplastic engineering plastic. Types of PPS resin include both the cross linked and linear type.

Toray engages in total production from base polymers to compounds, offering a wide variety of grades.

Features

■Heat resistant

Outstanding long-term heat resistance properties (UL temperature index 200-240°C, UL File No. E41797).

■Dimensional stability

Minimum molding contraction rate and coefficient of linear thermal expansion with low moisture absorption means outstanding dimensional stability even at high temperature and high humidity.

■Chemical resistance

Outstanding chemical resistance on par with fluoroethylene resin.

■Mechanical properties

The resins offer high strength and high rigidity with minimum decline in characteristics at high temperatures. Outstanding anti-fatigue and anti-creep properties.

■Flame retardant

Conforms with UL94V-0 without inclusion of flame retardant agents (UL File No. E41797).

■Electrical properties

Offers outstanding electrical properties at high temperature, high humidity and high frequencies.

■Molding properties

Outstanding fluidity allows injection molding on a level with standard engineering plastics.

Featured grades

TORELINA™ PPS Resin for Water Applications:
A604WR, A673MT/A673MWR, A670R63

These materials are ideal for applications involving water circulation, such as water heaters (valves, coupling joints, etc.), sanitary areas (faucets, etc.), and residential plumbing joints. Furthermore, water approval/certifications have been acquired in various countries.

A Range of Materials with Excellent Dimensional Accuracy for Communications Equipment and Sensor Components

Communications devices and sensor components used in technologies such as 5G communication and autonomous driving require dimensional accuracy, which requires resin materials that have a low level of warpage. To that end, Toray has now developed PBT and PPS resins with reduced warpage, which is one of the challenges faced by crystalline engineering plastics.

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.
