Heat-Resistant Protective Film
A high-temperature protective film that maintains stable physical and chemical properties in environments up to 250°C. Ideal for protecting surfaces during heat-based processes such as glass tempering, powder coating curing, and other manufacturing operations that involve elevated temperatures.
Key Features
- High-temperature films can maintain stable physical and chemical properties in high-temperature environments, typically withstanding temperatures ranging from 150°C to 260°C or even higher
- They have a low thermal expansion coefficient, allowing them to maintain dimensional stability during temperature changes
- High-temperature films exhibit excellent corrosion resistance to a variety of chemicals, maintaining stability in harsh environments such as acids, bases, and solvents
- Their antioxidant properties enable long-term use in high-temperature oxidation environments
- They possess high mechanical strength and toughness, capable of withstanding significant tensile and compressive forces
- Their good wear resistance ensures long-term use in harsh environments without easy damage
- High-temperature films have excellent electrical insulation properties, providing reliable electrical insulation in high-temperature and high-pressure environments
- Applications: It is applied in circuit board protection, motors and transformers, engine components, battery protection, 3D printing, and food processing

Frequently Asked Questions
What temperature range does the film withstand?
Our heat-resistant film maintains stable performance from -30°C to 250°C for continuous exposure. Short-duration spikes to 300°C are tolerated without significant degradation. The film does not become brittle or delaminate within this range.
What is the film made from?
Base film: PET (polyethylene terephthalate) with a silicone-based thermally stable adhesive. Optional formulations include polyimide (PI) film for extreme high-temperature applications above 250°C.
Will it leave residue after high-temperature exposure?
No. The silicone adhesive is engineered to remain removable even after multiple thermal cycles. Residue-free peel is guaranteed after standard operating temperature exposure. Extreme conditions above 300°C may reduce clean-peel performance.
Can it be custom-printed?
Yes. Heat-stable inks are used for print applications. Printing capabilities include process identification, batch numbering, and warning marks.
What industries commonly use this film?
Glass tempering and lamination, powder coating operations, aluminum extrusion, automotive paint booths, electronics assembly, and any process where surface protection must survive elevated temperatures.
