A smaller diameter sized wire and cable results in easier routing in small spaces. When the medical device shrinks, the components need to shrink as well so as to maintain the proper flexibility. mPPE insulation allows reduced wall thicknesses to make this possible. mPPE is able to be successfully used in stringent environments such as hospitals, as it has been approved as a suitable insulation for more than one hundred AWM cable styles and carries a VW-1 flame rating. While its properties and benefits are innovative, mPPE insulation still abides by the stringent UL and CSA Ratings. Lastly, and perhaps most significant for the future of medical devices is the introduction of the RoHS 2 directive, which now includes medical devices. This addition will change the face of medical devices, as they come under greater scrutiny for their inclusion and use of hazardous materials. With this in mind, mPPE insulation can provide an alternative to harmful PVC in order meet such guidelines. Devices such as portable x-ray machines and diagnostic equipment can all benefit significantly from the use of mPPE insulation.
