Polyimide Film Electrical Insulation Tape Class H With Silicone Adhesive

Description:


The Polyimide Film Electrical Insulation Tape utilizes high-performance polyimide film as the base material and is coated on one side with specially formulated imported silicone pressure-sensitive adhesive. This combination enables the product to not only inherit the excellent electrical insulation, chemical resistance, and flame retardancy of polyimide film but also incorporate the unique wide-temperature tolerance and long-term bonding stability of silicone adhesive. It maintains structural integrity and adhesive strength even under harsh conditions, effectively resisting moisture, chemical solvents, and corona discharge. As a result, this product has become an indispensable key material in the manufacturing of high-end motors, electrical appliances, and electronic products, providing robust support for the reliability and miniaturization of modern industry.

Advantages:

  • Exceptional Temperature Resistance & Insulation
    Offers high dielectric strength and reliable Class H insulation protection, effectively preventing electrical breakdown. Maintains stable performance in high-temperature environments to ensure long-term safety.
  • Strong Adhesion & Residue-Free Removal
    Achieves an optimal balance between firm bonding and easy release. Excellent cohesion ensures smooth unwinding and clean removal without residue, perfectly protecting bonded surfaces.
  • Superior Physical & Chemical Protection
    The robust base material resists puncturing, while the adhesive layer effectively defends against moisture, solvents, and corona discharge. Provides comprehensive and durable protection for components in harsh environments.
  • Premium Appearance & Easy Processing
    The roll is flat with a uniform adhesive layer, free from bubbles and bleed-out. Precision slitting delivers neat edges, ensuring smooth and efficient automated application.


Application:

  • Electronics Circuit Manufacturing & Protection
    Ideal for PCB wave soldering masking, gold finger protection, and high-temperature shielding and insulation for SMT components and electronic switches, ensuring circuit safety.
  • Motor & Transformer Insulation
    Serves as a Class H insulation material for coil wrapping and end fixation in motors and transformers, delivering durable insulation and structural stability under high temperatures.
  • Lithium Battery Assembly & Fixation
    Used for tab and module fixation and insulation in lithium batteries, withstanding operational temperature rises and electrolyte exposure to ensure battery safety and longevity.
  • Flexible Circuits & High-Temp Components
    Suitable for FPC reinforcement, insulation, and high-temperature process protection, providing reliable insulation and moisture resistance for heat-intensive components.
