Direct Answer

PET film (Polyethylene Terephthalate film) is a high-performance polyester material known for its excellent electrical insulation, thermal resistance, and mechanical strength. It is widely used in industrial applications such as insulation tapes, flexible packaging, electronic components, and transformer insulation.

Quick Facts

What is PET Film

PET film is a biaxially oriented polyester film (BoPET) produced through extrusion and stretching processes. It offers a combination of transparency, strength, and insulation performance.

• Base material: Polyester (PET)
• Structure: Film + adhesive (for tapes)
• Main uses: Insulation, packaging, industrial protection

Why PET Film is Used for Electrical Insulation

High Dielectric Strength

PET film provides excellent insulation, making it suitable for transformers and cables.

Heat Resistance

It can withstand continuous temperatures up to 130°C and short-term peaks up to 180°C.

Chemical Stability

Resistant to oils, solvents, and moisture.

Mechanical Durability

High tensile strength ensures durability in demanding environments.

Types of PET Film

• Single sided polyester tape
• Double sided polyester tape
• Flame retardant PET tape
