Dow Corning has introduced Silastic LC-70-2004, a 70 shore hardness liquid silicone rubber (LSR) offering high clarity, good mechanical properties and a short process cycle time that will be an attractive option for high-speed manufacturers. It is suitable for the precision-manufacture of complex parts such as high-performance mobile phone keypads, butterfly valves for food dispensers, kitchen ware, spatulas and silicone mats.
The new LSR features shorter cycle times and improved manufacturing throughput compared with high consistency rubber. Applied through an automated injection process, it offers smooth release from mould, low compression set, high tear strength, and a formulation that meets FDA21 CFR 177.2600 and BfR, XV food contact standards.
