Para-aramid Filmmictron™

Para-aramid Film mictron™

mictron™ is para-aromatic polyamide (aramid) film, first developed by Toray.

mictron™ has the highest modulus of elasticity of any film on the market, and thermal insulation close to polyimide. Furthermore, it is a film with properties useful as industrial materials, such as surface smoothness, low hygroscopicity, gas barrier properties, and chemical resistance.
