What is Polyester Tape?
Polyester tape, also referred to as PET tape, is made from a polyethylene terephthalate backing combined with a pressure-sensitive adhesive—typically silicone, acrylic, or rubber-based. Unlike standard plastic tapes, polyester tape offers superior resistance to heat, chemicals, and mechanical stress, making it a go-to solution in high-demand environments. Available in a range of thicknesses, widths, and adhesive types, polyester tape is valued for its precision masking capabilities, dielectric performance, and clean release properties. Its excellent dimensional stability ensures it maintains its shape under pressure, making it ideal for industries like electronics, automotive, aerospace, and metal finishing.

Key Properties & Benefits
One of the biggest advantages of polyester tape is its thermal stability. Most PET tapes can withstand temperatures between 130°C to 200°C, with silicone adhesive variants handling even higher exposure. This makes them ideal for high-heat processes like powder coating, wave soldering, and coil insulation. Additionally, polyester tape resists a wide range of chemicals, including solvents, oils, and acids, while maintaining strong adhesion and tear resistance. Many versions are designed for clean removal, leaving no residue behind after curing or processing. The tape’s clarity, color options (like green or amber), and compatibility with die-cutting also add to its versatility. Whether you need short-term masking or long-term insulation, polyester tape delivers consistent performance across applications requiring heat resistance, surface protection, and mechanical strength.
Applications of Polyester Tape
Polyester tape is widely used for high-temperature masking during powder coating, anodizing, and electroplating, due to its ability to withstand curing cycles without melting or leaving residue.
Splicing of Films and Paper
Due to its strength and clean adhesive system, polyester tape is used for web splicing in converting industries like packaging, paper, and film production.
It provides dielectric insulation in transformers, coils, motors, and PCBs, particularly in Class B and H systems where moderate heat resistance is needed.
Surface Protection
Its chemical resistance makes it ideal for temporary surface protection in manufacturing, especially for glass, metal, and painted components.
