PET film adhesive tape is a tape made of polyethylene terephthalate (PET) film as the base material and coated with an adhesive (such as acrylic, rubber or silicone). With the comprehensive properties of PET materials, this tape is widely used in industry, electronics, packaging and other fields, combining functionality, economy and easy processing.

Main features:

1. High mechanical strength and durability

- PET substrate has high tensile strength (usually >100 MPa), tear resistance and wear resistance, suitable for long-term fixation or surface protection.

2. Good temperature resistance

- Conventional models have a temperature range of **-40°C to 150°C**, and can withstand higher temperatures (such as 180°C) in the short term, but lower than polyimide tape, suitable for general industrial environments.

3. Excellent electrical insulation

- High dielectric strength (about 30-50 kV/mm), commonly used for electronic component insulation, temporary circuit board fixation or cable bundling.

4. Chemical stability

- Resistant to weak acids, weak bases and some organic solvents, but strong acids, bases or high temperature environments may affect performance.

5. Transparency and printability

- The substrate has high transparency (light transmittance > 90%) and can be made into transparent, colored or printed tapes, suitable for labels, packaging and other fields.

6. Environmental protection and processability

- PET materials are recyclable, easy to die-cut and punch into complex shapes, and suitable for automated production lines.

7. Economic efficiency

- The cost is significantly lower than that of polymer materials such as polyimide, suitable for large-scale applications.

Classification and special functions:

By adhesive type:

- Acrylic adhesive: high adhesion and aging resistance.

- Rubber adhesive: strong initial adhesion, suitable for rough surfaces.

- Silicone: high temperature resistant and easy to peel off.

By functional characteristics:

- Antistatic type: used for precision electronic assembly.

- Flame retardant type: meets UL94 VTM-0 standard.

- Weather-resistant: UV-resistant, suitable for outdoor signs.

Typical application scenarios:

- Electronic appliances: circuit board shielding, component fixing, screen protector substrate.

- Packaging and printing: sealing tape, label substrate, product anti-counterfeiting sticker.

- Industrial manufacturing: surface protection (such as metal, glass), lightweight material bonding.

- Daily life: office tape, DIY decoration, temporary repair.
