Dec. 30, 2009

For medical devices subject to the detrimental effects of vibration, impact, shock, and thermal cycling, MasterSil 151 Med, a two-component, medical-grade room-temperature curing potting and encapsulation silicone reliably withstands such events. With a viscosity of 1,500 cps, it’s desirable for use in applications with complex contours. Other features include a volume resistivity of 1 x 1,015 ? cm, an operating temperature range from -65°F to +400°F, a refractive index of 1.43, shrinkage upon cure of less than 0.1%, Shore A hardness of 45, an elongation at break of 160%, a tensile strength of 880 psi at 73°F, and a mix ratio of 10:1 by weight.
