View DetailsOur primary high-temperature offering includes the TF300 and TF310 polyimide adhesive tape series. Formulated with a tough polyimide backing and premium silicone adhesives, these tapes operate continuously at temperatures up to 260°C. The TF310 offers exceptional adhesion and insulation, while the Double TF310 provides dual-sided silicone adhesive performance separated by a release liner, perfect for secure mounting and thermal bonding. These silicone-based tapes ensure complete protection during wave soldering and high-temperature powder coating, peeling away cleanly without leaving any adhesive residue.
For applications requiring high initial tack and robust bonding under varied temperatures, we manufacture polyimide rubber adhesive tapes. Combining the excellent dielectric strength and thermal endurance of polyimide film with the aggressive tack of a natural rubber adhesive, this tape provides highly dependable electrical insulation. It is widely used in motor coil wrapping, electrical insulation blankets, and high-stress industrial applications where immediate, high-shear adhesion is necessary.
When both thermal insulation and visual opacity are required, the Black TF310 polyimide tape offers an ideal solution. This tape features a black-pigmented polyimide film carrier coated with a high-temperature silicone adhesive. It delivers the same outstanding dielectric strength and heat resistance as our standard amber tapes, but with the added benefits of light-blocking and aesthetic uniformity. This makes it heavily utilized in optical sensors, automotive manifolds, and sensitive semiconductor shielding applications.
We are committed to providing our customers with the best possible service, from initial consultation to final delivery and beyond.
Extensive inventory and efficient logistics ensure your orders arrive on time, every time.
Rigorous testing and inspection protocols guarantee the highest quality insulation materials.
Our dedicated team of experts is available around the clock to assist with any technical inquiries.
Both TF300 and TF310 feature high-temperature silicone adhesives on a polyimide film backing, offering heat resistance up to 260°C and clean, residue-free removal. TF300 is optimized as a cost-effective solution for standard PCB wave soldering masking and coil protection. TF310 is formulated for applications demanding even higher mechanical adhesion and dielectric strength, and it is available in double-sided (Double TF310) and opaque black (Black TF310) configurations.
You should choose polyimide tape with rubber adhesive when your application requires extremely high initial tack (quick stick) and high mechanical shear strength at moderate-to-high temperatures. Silicone adhesive tapes are preferred for applications involving extreme heat (up to 260°C) and where clean, residue-free removal is mandatory after thermal exposure, such as SMT reflow and high-temperature powder coating.
Yes. We can supply our polyimide tapes with or without a release liner, which is particularly useful for die-cutting operations and double-sided tapes (like Double TF310). We can accommodate custom slitting to precise widths (from 4mm up to 500mm) and custom lengths (such as 33m or 66m per roll) to align with your automated assembly or manufacturing lines.
