mPPE, which stands for Modified Polyphenylene Ether, is a thermoplastic just like its PVC competition, and can be repeatedly heated and formed into any shape while hot. mPPE insulation was first used in the automotive industry, to provide an eco-friendly and performance enhancing alternative to PVC used in 60% of the vehicles. The reduced weight was also an important feature to improve fuel efficiency of their vehicles. This new material quickly garnered attention in the industry for its benefits and application uses beyond those in the automotive industry.
