Dow has launched a new liquid silicone rubber (LSR) series suited for the mobility and transportation sector. The general purpose and self-lubricating Silastic SA 994X LSR series is a range of primerless, self-adhesive, one-to-one mix ratio material designed for two-component injection molding with thermoplastic substrates including, but not limited to, polybutylene terephthalate and polyamide.
The Silastic series can be used across multiple automotive applications, such as connector seals, battery vent gaskets, and radiator gasket seals in electric and hybrid vehicles, as well as environmental protection seals for autonomous vehicles’ lidar and radar housings. The launch builds on Dow’s previously announced capacity expansions and investments for the mobility and transportation market, which included the installation of a new LSR mixer at its production site in Zhangjiagang, China, in 2021.
“The investments we’ve made in our LSR capacities were both an exciting and necessary step for us as we work to provide the best possible material solutions for our mobility customers,” said Jeroen Bello, Global Marketing Director for Mobility and Transportation, Dow Consumer Solutions. “Our expanded ability to produce these technologies has enabled further advancements from our engineers, which deepens the level of collaboration that we bring to the table.”
The products within the series offer automotive manufacturers several key benefits including:
Durable adhesion under heat and humidity;
instant development of full bond strength;
12-month shelf-life stability;
robust and instant adhesion to multiple plastic and metal substrates throughout the products’ shelf life without the need for further heat treatment.
“As the requirements of automotive OEMs and tiers continue to evolve in response to the rapid changes occurring throughout the industry, it’s of the utmost importance that they have the tools they need to keep up to speed,” said Bello. "LSRs are a critical material in multiple mobility and transportation applications and our team at Dow is continuously working toward greater global-level innovation within this product category. With the addition of the Silastic SA 994X LSR series to our portfolio, we are even better positioned to support the needs of our customers today and in the future.”
