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 (Green PET Series) is an elite shielding solution engineered for extreme thermal and chemical environments. Combining a premium green PET (Polyester) film backing with a specialized heat-resistant silicone adhesive, this tape reliably withstands temperatures up to 260°C (500°F). Its high-visibility green color and outstanding chemical resistance make it the industry standard for powder coating, electroplating, anodizing, and electronics manufacturing, guaranteeing clean, residue-free removal even after intense heat cycles.
Extreme Heat Resistance (Up to 260°C): Specially formulated to survive extreme conditions like powder coating curing ovens and autoclave cycles without melting, shrinking, or degrading.
Superior Chemical & Acid Resistance: The PET backing and silicone adhesive system are highly resistant to harsh solvents, acids, alkalis, and plating solutions, ensuring structural integrity in aggressive environments.
Strong Adhesion & Zero Residue: Provides excellent grip on metals, glass, and PCBs, but is engineered to peel off easily in one piece, leaving absolutely zero sticky residue behind.
High-Visibility Green Color: The distinctive green color provides high contrast against most metal and painted surfaces, making it easy to apply accurately and ensuring no masking spots are missed before processing.
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.
Electroplating & Anodizing: Its exceptional acid and alkali resistance makes it ideal for masking specific areas during chemical etching, electroplating, and anodizing baths.
Electronics & Battery Manufacturing: Used for insulating and wrapping lithium-ion battery cells, transformer coils, and motor components, as well as masking PCB gold fingers.
Automotive Painting & Baking: Protects trim, glass, and sensitive electronics during spray painting and high-heat paint booth bake cycles.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
The high-visibility green color is an industry standard for high-temperature PET tapes. It provides excellent contrast against most metal, painted, and PCB surfaces, making it easy for operators to apply accurately and ensuring no masking spots are missed before the parts enter the powder coating oven or plating bath.
Yes. Unlike standard masking tapes, our Green PET tape utilizes a specialized silicone adhesive and a dense polyester backing that is highly resistant to harsh acids, alkalis, and plating solutions. It effectively masks off threaded holes and contact points during chemical etching, electroplating, and anodizing baths without degrading.
No. Our heat-resistant silicone adhesive system is specifically formulated to remain chemically stable under extreme thermal stress (up to 220°C long-term / 260°C short-term). Unlike rubber-based adhesives that melt and bake onto surfaces, our tape peels off cleanly in one piece without tearing or leaving any sticky residue.
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 PCB masking and battery wrapping.
