Styron has launched two new grades in its Sprintan portfolio for tyre manufacture. Sprintan SLR 3402 and SLR 4502 are aimed at improved performance at low-temperatures, and feature a ‘microstructure’.
The products are said to display the same features as other Sprintan grades, namely low rolling resistance, as well as reduced stiffness at low temperatures, boosting snow grip potential in winter tread applications. Both can be blended with other polymers.
For Ultra High Performance (UHP) car tread, Sprintan SLR 4502 and 3402 can be applied to partially replace high-Tg SSBR and BR, claims Styron. They offer reductions in rolling resistance due to a ‘functionalisation technology’ which works with silica as well as with carbon black fillers.
Olivier Veron, Marketing Manager of Styron’s Rubber Business said: “The microstructure of these new grades clearly differentiates them from our existing rubber portfolio and can be positioned as best-in-class among our products of non-oil extended grades. Styron is committed to innovate and develop tyre solutions by working closely with our customers who are a source of inspiration on a daily basis. Forging ahead, we will continue to partner with customers to design next generation rubber products and technology that will help them upgrade their tyre line to address future trends and global regulatory standards.”
