Kraft Paper

Insulating kraft paper is a specialized material primarily used for electrical insulation in various applications, such as transformers, capacitors, and cables. It is made from unbleached wood pulp and offers excellent dielectric properties, making it suitable for preventing unwanted electrical conductivity.

Key Properties of Insulating Kraft Paper

  • Composition: Typically composed of 100% unbleached kraft wood pulp, ensuring high strength and durability.
  • Thickness Options: Available in various thicknesses ranging from 1.5 Mils to 20 Mils, allowing for flexibility in application requirements.

Key Advantages-

  1. High Tear Strength: Ensures longevity and resistance to mechanical stress.
  2. Low Elongation: Maintains dimensional stability under varying conditions.
  3. Effective Insulation: Prevents electrical current flow, safeguarding components from short circuits
