Stephen LawProduction / Materials Medical epoxy materials medical production system
MASTER BOND EP41S-5Med two part epoxy system meets the requirements of ISO 10993-5 for non-cytotoxicity and can be used for bonding, sealing and coating in medical devices. Product features high temperature resistance and enhanced strength properties. Epoxy was tested against many sterilization methods, such as autoclaving, STERRAD, Cidex and Steris, successfully resisting a hundred cycles. It is also capable of withstanding exposure to gamma radiation, ethylene oxide, as well as other aggressive sterilants and chemicals. Product provides a tensile strength of 10,000-12,000 psi and adheres well to a variety of similar and dissimilar substrates, including metals, plastics, rubbers, ceramics, and composites. Compound has a glass transition temperature of 140-145°C and is serviceable from -80°F to +450°F [-62°C to +232°C]. EP41S-5Med features reliable electrical insulation characteristics with a dielectric constant of 3.5 at 60 Hz and a volume resistivity greater than 1014 ohm-cm.
