Low viscosity PPS
Ticona Engineering Polymers, the world’s largest supplier of linear polyphenylene sulphide (PPS), has introduced a low viscosity grade that meets today’s market demand for low halogen materials.

Though similar to the low chlorine Fortron PPS 1140A66, this next generation Fortron PPS gives designers and manufacturers a “drop-in” option for use in eco-friendly electrical and electronic components. The resin also meets the proposed industry standard by containing less than 900 parts per million of both bromine and chlorine, which enables it to compete against other PPS low halogen products as well as high-temperature V-0 nylons. Since it is UL94 V-0 rated, it can withstand high temperature soldering assembly — up to 270°C — and it is said to outperform high temperature nylons that are subject to blistering, moisture uptake and dimensional stability processing issues.
