Liquid silicone rubber for high-speed manufacturing

Dow Corning has introduced Silastic LC-70-2004, a 70 shore hardness liquid silicone rubber (LSR) designed to provide high clarity, superior mechanical properties and short cycle time for high-speed manufacturers.

The new product is particularly well suited for precision-production of complex parts such as high-performance cellphone keypads, butterfly valves for food dispensers, bakeware, spatula and silicone mats.

Silastic LC-70-2004 offers shorter cycle times and improved manufacturing throughput compared to high consistency rubber. When applied through an automated injection process, Silastic LC-70-2004 offers smooth release from the mold to help customers produce complex parts designs with consistency. The new LSR also features high transparency, low compression set, high tear strength, and is formulated to meet FDA21 CFR 177.2600 and BfR, XV food contact standards.
