Standard Grade Polyimide Film- for Reliable Electrical Insulation and Cost-Efficient Designs

High Performance Polyimide film  PIF - for Reliable Electrical Insulation and Cost-Efficient Designs

Product Description: 

Standard Grade Polyimide Film PIF is a high-performance, heat-resistant insulation film designed for general-purpose electrical and electronic applications requiring reliable performance under extreme temperature conditions. 

Engineered with an excellent balance of mechanical strength, electrical insulation, and chemical stability, PIF operates across an exceptionally wide temperature range—from cryogenic −452°F (−269°C) to continuous high temperatures of +500°F (+260°C), with short-term resistance up to +752°F (+400°C). This makes it one of the most thermally stable and versatile insulation films available for industrial use.

Besides, it offers high dielectric strength, low stiffness, and atomic radiation resistance, ensuring long-term durability and dependable performance in harsh environments. As a proven, cost-effective polyimide solution, PIF is widely adopted as a base insulation film in motors, transformers, flexible electronics, adhesive tapes, and specialty fabricated products.
