SiSiB® FL9140
SiSiB® FL9140

SiSiB® FL9140 is a platinum-catalyzed fluorosilicone rubber for liquid injection molding. It cures to a 60 Shore A elastomer, resistant to fuels, oils, solvents, and chemicals. With flexibility from -63°C to 175°C, and up to 225°C in dry heat environments it's perfect for sealing and insulating in extreme conditions.

SiSiB® FL9140

Features


  • Excellent resistance to automotive fuels and lubricating oils


  • Rapid cure with no cure by-products


  • Outstanding high-temperature resistance


  • Broad cure temperature range (130-200°C)


  • Excellent solvent resistance
