Dow Corning Corp. has introduced two Silastic brand F-LSRs to expand design options and provide processing efficiency for fuel-resistant automotive components.
The newest product offerings add 60 and 70 durometer hardness options.
The Silastic F-LSRs meet market needs for both performance and cost control, Dow Corning said, and combines the fuel, oil and solvent resistance of fluorosilicone rubber with the processing benefits of liquid silicone rubber.
This latest fluorosilicone elastomer technology from Dow Corning can help designers develop more durable components for withstanding severe operating environments, the firm said, and can help fabricators achieve manufacturing improvements with automated processing, reduced labor costs, shorter cycle times, energy savings and reduced scrap rates.
The two newest Silastic fluoro liquid silicone rubbers in Dow Corning's product range are Silastic FL 60-9201 F-LSR (60 Shore A durometer) and Silastic FL 70-9201 F-LSR (70 Shore A durometer). According to the company, both exhibit resistance to nonpolar hydrocarbon fuels, oils and solvents and offer process cost savings, especially for molding small parts in high volumes. Silastic FL-60-9201 F-LSR provides flexibility for dynamic seals such as diaphragms and membranes, Dow Corning said, while Silastic FL 70-9201 F-LSR provides high modulus with low compression set for static seals such as O-rings and gaskets.
