PI HEAT RESISTANT TAPE (TDS-Technical Data Sheet)
Product Model: 80050Y
1. Product Description
PI high temperature tape uses Polyimide film as the base material, on which a modified pressure sensitive adhesive is coated. PI tape can be divided into two types according to the adhesive: PI silicone tape and PI acrylic tape.
2. Basic Product Structure
- Polyimide
- Silicone /Acrylic glue)
3. Product Characteristics
PI tape has a flexible polyimide base material with excellent electrical insulation and heat resistance. PI film can withstand temperatures exceeding 400°C. If coated with a modified silicone pressure-sensitive adhesive, its temperature resistance can reach 280°C. If coated with an acrylic pressure-sensitive adhesive, it exhibits excellent adhesion and weather resistance.
4. Product Application Scope
- PI silicone tape is primarily used in applications requiring high-temperature resistance or high initial adhesion, such as insulation and wrapping for H-class motor and transformer coils, wrapping and securing high-temperature coil ends, protecting RTDs, detangling capacitors and wires, and other applications requiring high-temperature insulation, protecting PCB gold fingers and electronic components during surface-mount mounting (SMT), and wrapping polymer lithium batteries.
- PI acrylic tape is commonly used for PCB insulation, securing and wrapping wire harnesses, wrapping transformer coils between layers and on the outside, and insulating lithium batteries.
