Product Description

High temperature resistant silicone PI yellow single-sided tape uses polyimide as the base material, the most heat-resistant industrialized polymer material known as the "golden film". It offers high oil resistance, low dielectric loss, and excellent chemical stability.

This tape features strong adhesion, acid and alkali resistance, and low electrolysis. After removal, the surface remains clean without any residual glue. It is fully compliant with ROHS environmental protection and halogen-free standards.

Applications & Features

Electronics: Ideal for gold finger protection during reflow and wave soldering.
Insulation: Used for H-class or C-class insulation in motors, transformers, and lithium batteries.
Durability: Resistant to anti-voltage breakdown (5kw-50kw) and chemical erosion.
Advanced Tech: Widely used in aerospace, OLED lighting, solar cells, and mobile communications.
