Second, the specific insulation materials used in batteries can vary depending on the type of battery, its intended application, and industry requirements. Polyester (PET) — PET offers good electrical insulation properties, high tensile strength, chemical resistance, and dimensional stability.
1. Polypropylene film for electrical and thermal insulation of batteries and accumulators Polypropylene has excellent dielectric properties, excellent impermeability, and is easily deformed. Formex is the first choice for engineers and designers. It is very durable and has excellent dielectric strength.
The following 6 materials are used for the electrical and thermal insulation of batteries and accumulators: 1. Polypropylene film for electrical and thermal insulation of batteries and accumulators Polypropylene has excellent dielectric properties, excellent impermeability, and is easily deformed.
It is often used in battery separators. Fiberglass — A composite made of fine glass fibers, this material helps as a thermal and electrical insulation material due to its high strength, resistance to chemical corrosion, and low thermal conductivity.
2. Polyester films for electrical and thermal insulation of batteries and accumulators Polyester films (also known by the trade names Mylar and hostaphane) are also used in many applications where electrical insulation, heat resistance and dimensional stability are required.
Typically, polyolefin materials, such as porous polyethylene (PE) or polypropylene (PP) are used in liquid electrolyte Li-ion batteries because of their low cost and wide chemical stability.
