High temperature masking tape is designed to withstand high temperatures, often up to 260°C (500°F), making it suitable for use in extreme conditions like powder coating or automotive painting. Suitable for use in multiple industries such as electronics, automotive, aerospace, and painting.
Backed by Jiangsu Gelly Adhesive Material Technology Co., Ltd and our 30 years of special tape expertise, our High Temperature Masking Tape (Yellow PET Series) is an elite shielding solution engineered for extreme thermal environments. Combining a premium yellow PET (Polyester) film backing with a specialized heat-resistant silicone adhesive, this tape reliably withstands temperatures up to 260°C (500°F). The high-visibility yellow color serves as an excellent safety indicator and process marker in industrial facilities, while its outstanding chemical resistance makes it the preferred choice for powder coating, automotive baking, and LED manufacturing, guaranteeing clean, residue-free removal.
Extreme Heat Resistance (Up to 260°C): Specially formulated to survive extreme conditions like powder coating curing ovens, autoclave cycles, and automotive paint baking without melting, shrinking, or degrading.
High-Visibility Safety Yellow: The vibrant yellow color acts as a universal safety and caution indicator. It allows operators to instantly identify masked high-heat zones and ensures no masking spots are missed before parts enter the oven.
Superior Chemical & Solvent Resistance: The dense PET backing and silicone adhesive system are highly resistant to harsh solvents, acids, alkalis, and paint thinners, ensuring structural integrity in aggressive environments.
Zero Residue Clean Removal: Provides excellent grip on metals, glass, and PCBs, but is engineered to peel off easily in one piece after heat exposure, leaving absolutely zero sticky residue behind.
High Tensile Strength & No Tearing: The robust PET film backing prevents the tape from tearing or breaking during removal, minimizing surface damage and eliminating costly post-process cleaning.
Powder Coating & Industrial Ovens: Effectively masks off threaded holes, grounding points, and contact surfaces during high-temperature powder coating and curing processes.
Automotive Painting & Baking: Protects trim, glass, and sensitive electronics during spray painting and high-heat paint booth bake cycles.
LED & Electronics Manufacturing: Widely used for masking and securing components during LED reflow soldering and high-heat electronic assembly where a yellow visual indicator is required.
Safety Zone Marking in Ovens: Its caution-yellow color makes it ideal for temporary high-temperature zone marking and protecting fixtures inside industrial curing ovens.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
In industrial facilities, yellow is the universal color for caution and safety. Many factories use Yellow PET tape to clearly mark high-heat zones, identify specific curing processes, or distinguish it from green/blue tapes used for other temperature grades. It prevents operator errors and ensures the correct tape is used for every 260°C process.
No. Our heat-resistant silicone adhesive system is specifically formulated to remain chemically stable under extreme thermal stress. Unlike rubber-based adhesives that melt and bake onto surfaces, our yellow PET tape peels off cleanly in one piece without tearing or leaving any sticky residue, eliminating post-process cleaning.
Yellow PET tape (up to 260°C short-term) is highly cost-effective and offers excellent chemical resistance, making it ideal for powder coating, automotive baking, and LED manufacturing. Amber Polyimide (Kapton) tape offers even higher thermal stability (up to 300°C) and superior electrical insulation, making it the standard for PCB gold fingers and electronic components.
Absolutely. As a direct manufacturer with 30 years of experience, we supply standard jumbo rolls for tape converters and offer comprehensive OEM/private-label services. We utilize advanced high-speed slitting machines to provide custom narrow widths starting from 3mm, ideal for precise masking and automated manufacturing lines.
