Tokyo, Japan— Tosoh has developed a polyphenylene sulfide (PPS) compound featuring enhanced thermal shock resistance 1 resulting in an 80% improvement over current industry-standard products.
In recent years, growing demand for PPS resins has been forecast in line with the increasing popularity of electric vehicles; and the increasing shift toward the use of materials other than metal with the aim to reduce the weight of automobiles for improved fuel and power consumption. There are many automobile parts such as metal terminal connectors and electrodes that are manufactured through metal insert-molding2, and it is important to improve the thermal shock resistance of these parts made of materials with different shrinkage rates and other properties.
The new product features improved weld strength3 and liquidity, and can be expected to contribute to further reductions in the weight of automobiles through thinning and compounding.
Going forward, the company will begin sample development and is currently considering mass production of the product.
As Japan’s first PPS resin manufacturer, Tosoh will continue to apply its technological capabilities based on years of accumulated knowledge to new product development.
