NuSil Technology LLC, a leader in silicone materials for the healthcare, pharmaceutical and drug delivery industries, introduces MED-5440, a translucent 100 mol % fluorosilicone elastomer designed to be used with liquid injection molding equipment.

NuSil MED 5440

As a fluorosilicone, MED-5440 resists swell when in contact with or immersed in dimethyl fluids and most solvents or oils.  Some typical applications for MED-5440 include O-rings, gaskets, seals, and precision molded parts for implant applications requiring silicones of medium durometers that resist swell. 

“MED-5440 is an excellent choice for molding high quality silicone parts that require some degree of resistance to solvents, alcohols, fluids or oils,” said Brian Reilly, Marketing & Sales Director — Medical Implants. “This versatile product can be ideal for molding septums, o-rings or gaskets for which swelling is a concern when the device is exposed to certain environments.” 
MED-5440 is a two-part silicone rubber with a 1:1 mix ratio and a Type A durometer of 40.  Designed for liquid injection molding processes, the MED-5440 cures rapidly when exposed to heat.
