Heat Resistant Silicone Adhesive Tapes (Polyester Silicone Tape / Polyimide Silicone Tape) for PCB SMT FPC Battery High Temp. Masking

Silicone adhesive tape is a high-performance pressure-sensitive tape made with silicone adhesive coated on substrates such as PET film, polyimide (PI) film, or cloth(teflon cloth, glass cloth). Its key advantages include ultra-wide temperature resistance, strong adhesion to low surface energy materials, clean removal without residue, and excellent weather and chemical resistance. These properties make silicone tape an essential material in industrial, electronics, medical, and new energy applications.

As silicone adhesive tape manufacturer, we provide high quality self-adhesive sticky silicone tape including single sided silicone tape and double sided silicone tape.

Features of Silicone Adhesive Tapes：

Clean Removal Without Residue 
Leaves no adhesive residue after removal, even after high-temperature exposure.

High Temperature Resistance

Performs reliably from -50°C to 260°C (300°C short term), ideal for extreme heat and cold environments.

Strong Adhesion to Low Surface Energy Materials
Excellent bonding on silicone, PTFE, PE, PP, and other difficult-to-bond surfaces.

Different Types of Silicone Adhesive tapes
