Dennison Insulation Paper | Thermally Uprated Creped Paper

Chengrui supplies Dennison Paper equivalent thermally upgraded creped kraft paper for magnet wire taping, paper covered copper conductors, CTC conductors and oil-immersed transformer insulation systems.

This material is made from high-purity electrical grade cellulose kraft paper and processed with controlled creping and thermal upgrading treatment. Compared with standard kraft paper or ordinary crepe paper, it provides higher elongation, better tensile strength, improved flexibility and excellent compatibility with transformer oil.

What Is Dennison Paper?

Dennison Paper is a high-strength electrical insulation paper designed for machine taping of magnet wire and conductors. It is generally understood as a type of thermally upgraded creped kraft paper, but with stricter requirements for mechanical strength, elongation and tape running performance.

It is especially suitable for applications where the paper must withstand continuous wrapping, bending and stretching without breaking during high-speed taping.

Features Dennison Insulation Paper

• Material: 100% pure long-fiber sulfate cellulose Kraft paper.
