ITW Formex® Electrical Insulation Material Meets Requirements of Electric Vehicle Battery Covers

ITW Formex® announced the suitability of its Formex™ brand electrical insulation material for electric-vehicle battery applications. Automotive battery covers made from Formex polypropylene electrical insulation meet the demanding requirements of electric vehicle design and manufacture. Battery systems in electric vehicles include demanding environmental, mechanical, and chemical requirements while emphasizing safety and weight reduction. The material chosen for automotive battery covers must be lightweight, inexpensive, flame retardant, and meet rigorous electrical barrier and insulation requirements. To reduce OEM costs under maintenance service agreements, the battery cover material must be strong and serve reliably. Formex electrical insulation material meets all of these requirements, and unlike materials that need to be molded into parts, Formex is easily and economically formed into complex three dimensional parts by die-cutting, scoring, and bending. Its long-term thermal aging capabilities have been long recognized in other applications, making it ideal for reliable service in automotive environments. In addition, Formex is resistant to most battery chemistries. Formex delivers superior performance in comparison to other battery cover materials such as aramid paper. Aramid paper absorbs significantly more moisture, is less dimensionally stable, is more expensive, and does not provide score and fold capabilities. Because Formex is a better electrical insulator, thinner product can be used to reduce weight. To discuss your requirements please contact us on 01274 636333 or sales@presspahn.com.
