PTFE Film Acrylic Adhesive Tape is a composite industrial tape that combines the high-temperature resistance and anti-stick properties of pure Teflon (PTFE) film with the strong adhesion of acrylic adhesive. Its base material is a polytetrafluoroethylene film coated with a high-performance acrylic adhesive layer, possessing extreme temperature resistance (-70℃ to 260℃), chemical inertness, a low coefficient of friction, and excellent electrical insulation properties. Simultaneously, the acrylic adhesive layer achieves high-strength adhesion to materials such as metals, plastics, and glass. This product is widely used in food packaging, electronics manufacturing, machinery protection, and high-temperature processing, making it an ideal choice for industrial bonding and protection.
Characteristics and Advantages:
1. Excellent Temperature Resistance: The PTFE substrate enables the tape to withstand temperatures up to 260°C continuously, and can withstand extreme environments up to 300°C for short periods, while maintaining flexibility at low temperatures (not becoming brittle at -70°C). The acrylic adhesive layer is specially formulated to maintain stable adhesion at high temperatures, preventing detachment or failure.
2. Dual Anti-sticking and Easy-to-Clean Properties
The smooth surface of the PTFE film has natural anti-stick properties, effectively preventing the tape from sticking to the substrate, making it especially suitable for applications prone to adhesion, such as heat-sealing rollers and baking equipment. The acrylic adhesive layer is designed with a low-residue formula, minimizing adhesive residue during replacement and reducing cleaning and maintenance costs.
3. Strong Chemical Stability and Environmental Safety
Resistant to strong acids, alkalis, organic solvents, and oils, it meets FDA food contact standards, is non-toxic and odorless, and suitable for food packaging machinery and medical equipment. The acrylic adhesive does not contain volatile harmful substances and does not release toxic gases at high temperatures.
4. High Adhesion and Durability
Acrylic adhesive exhibits a balanced initial tack and shear strength, firmly bonding high surface energy materials such as stainless steel, aluminum alloys, and ceramics. It also boasts excellent anti-aging properties, maintaining its tack even after prolonged exposure to UV radiation or humid environments.
5. Versatile Physical Properties
- Insulation and Protection: Low dielectric constant (2.6), suitable for cable insulation and high-temperature soldering protection of circuit boards.
- Friction Reduction and Wear Resistance: With a coefficient of friction as low as 0.05, it can reduce wear when used for mechanical guide rails and bearing protection.
- Customizable Design: Available in thicknesses from 0.04-0.5mm, various widths (customizable up to 600mm), and colors (white/grey/black/transparent).
Typical Application Scenarios:
1. Food and Pharmaceutical Packaging
Used as anti-stick liner in heat-sealing and filling equipment to prevent packaging materials from melting and sticking together, improving production line efficiency.
2. Electronics and Electrical Appliances Industry
Used as high-temperature insulating tape to protect transformers and motor coils, or to fix heat-resistant electronic components such as LED heat sink modules and power adapters.
3. Industrial Manufacturing and Machinery Maintenance
- Adhesive to injection molding machine release plates and 3D printing heated beds for rapid demolding.
- Cover conveyor belts and roller surfaces to reduce material adhesion and extend equipment life.
4. Automotive and Aerospace
Used for fixing engine compartment wiring harnesses and bonding battery pack insulation layers, withstanding the high-temperature and vibration environment of engines.
