Ultra-High Temperature Tapes (Above 150°C)
-- Steady & Reliable Manufacturer --
Technical Overview
Ultra-High Temperature (UHT) tapes are engineered for sustained operation above 150∘C, relying on carriers such as Polyimide (Kapton® type), PTFE (Teflon® type), or high-purity fiberglass cloth, paired with highly stable silicone or specialized cross-linked acrylic adhesives. These materials resist degradation, charring, and significant loss of physical strength or adhesion when exposed to extreme thermal conditions.
The key metrics are the maximum continuous service temperature and short-term peak temperature limits. Polyimide and silicone systems are often specified for temperatures up to 260∘C and intermittent exposure even higher. Applications include masking during powder coating, high-temperature soldering, and permanent securing in engine bays or heating elements.
Why Choose Us
Differentiating Attributes
- Thermal Degradation Resistance: Carriers like Polyimide and Fiberglass do not melt, soften, or char, maintaining their physical barrier and dimensional stability under extreme heat.
- High-Stability Silicone Adhesives: Silicone adhesives provide the necessary adhesion while maintaining molecular integrity and non-corrosive properties up to 260∘C, far exceeding most other adhesive chemistries.
- Residue-Free Removal: Engineered for clean removal even after high-temperature curing cycles (e.g., 200∘C for 30 minutes), minimizing rework and cleaning costs.
- Excellent Chemical Resistance: High-temp carriers are typically chemically inert, making them suitable for use in high-heat environments where cleaning agents or solvents may be present.
- High Dielectric Strength: Often doubles as electrical insulation, maintaining high voltage resistance even at elevated operating temperatures.
- Thin Profile and Flexibility: Polyimide tapes are extremely thin and conformable, allowing for precise, high-density component wrapping without adding bulk.
Core Features
Applications
- Powder Coating Masking: Protecting holes, threads, and surfaces that must remain coating-free during the high-heat curing process (Polyimide or Polyester/Silicone).
- PCB Wave Soldering: Masking gold fingers and connectors on circuit boards during reflow or wave soldering (Polyimide/Silicone required).
- High-Temperature Coil Wrapping: Securing electrical insulation in motors and transformers rated for high thermal classes (Fiberglass/Silicone).
- Thermal Shielding: Acting as a protective wrap around components exposed to direct high heat, such as exhaust components or heating elements.
- Curing Composite Materials: Temporary holding and sealing during high-pressure, high-temperature autoclave curing cycles.

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: What is the main limitation of high-temp acrylic tapes compared to silicone?
- A: High-temp acrylics usually have a maximum continuous service temperature limit around 150∘C. Silicone adhesives are required for reliable, continuous performance above 180∘C.
- Q: Can high-temp tape be used for long-term exhaust sealing?
- A: For extremely high, long-term temperatures (e.g., above 350∘C), specialized ceramic or refractory tapes are needed. Polyimide/Silicone tapes are typically rated for sealing in environments up to 260∘C.
- Q: Why does Polyimide tape sometimes leave a slight residue after baking?
- A: This is often due to the cohesive failure of low-quality silicone adhesive or the use of a non-optimized adhesive-to-carrier bond. High-quality PI tapes are engineered to pull the adhesive cleanly from the substrate.
- Q: Are all UHT tapes electrically insulative?
- A: Most Polyimide and Fiberglass UHT tapes are highly insulative. However, some UHT tapes used for grounding or thermal management might be conductive (e.g., carbon-filled). Always check the dielectric strength specification.
