PE6497 Polyimide Impregnated Glass Varnished Cloth

Polyimide-impregnated, varnished glass fibre cloth Description:

Polyimide-impregnated, varnished glass fibre cloth is a high-performance insulating material produced by impregnating alkali-free electrical glass fibre with polyamic acid resin, followed by drying and imidisation. It exhibits excellent thermal stability, allowing for long-term usage at 200°C, along with radiation resistance, corrosion resistance, and solvent resistance. Additionally, it provides outstanding dielectric properties and mechanical strength, making it reliable for demanding electrical and electronic applications. This material is commonly used for the insulation of slots and end blocks in motors, as well as in various electronic components that require high durability and insulation performance.
