  • Excellent Dielectric Properties – Polyimide offers excellent dielectric properties, making it an excellent choice for applications where electrical insulation, high voltage, or low electrical conductivity are critical.
  • (1) Volume resistivity: 10 to the 13th power ohm cm / min. (ASTM D257)

  • Length: Available in 5m and 10m

  • The Industrial Revolution
  • Polyvinyl chloride (PVC) is a versatile and widely used material in the electrical industry due to its excellent electrical insulation properties. This article provides a comprehensive guide to PVC electrical insulation, including its properties, applications, advantages, and manufacturing process.
  • The primary function of this tape is to insulate and bundle together the numerous wires and cables, preventing them from chafing, fraying, or coming into contact with other components that could cause short circuits or damage. Its adhesive nature ensures a secure hold, even under the rigorous conditions inside a vehicle - be it extreme temperatures, vibrations, or exposure to oils and chemicals.
  • Tensile Strength: 4.73 Mpa

  • 5. Moisture Resistance Red insulation tape is also resistant to moisture, making it suitable for use in outdoor settings or areas exposed to humidity.


  • One of the key factors to consider when purchasing butyl rubber tape is the price. The cost of butyl rubber tape can vary depending on the brand, quality, and quantity purchased. Generally, butyl rubber tapes are quite affordable and can be purchased in rolls or cut to size according to the specific needs of the user.
