Red Express Paper Thickness: 0.2mm-0.5mm Double-sided tape: hot-melt cotton paper double-sided tape, oil-glue cotton paper double-sided tape Insulation class of red express paper: B class Breakdown voltage: greater than 4KV Red Express Paper Product Features The red fast paper has the functions of insulation and anti-interference, high electrical insulation, mechanical strength, softness and elasticity; the red fast paper is particularly resistant to acid and alkali corrosion, tear resistance and wear resistance, and is not sensitive to moisture. , Non-toxic and flame-resistant, red fast paper has strong inherent dielectric strength, mechanical toughness, flexibility and resilience, and good thermal stability. Factors affecting the performance of red express paper 1. Insulation resistance and resistivity: The smaller the conductivity of the material, the greater its resistance, and the two have an inverse relationship. For red fast paper insulation materials, it is always hoped that the resistivity is as high as possible. 2. Relative permittivity and dielectric loss tangent. 3. Breakdown voltage and electrical strength: Under a certain strong electric field, the red fast paper insulating material is damaged, and the insulating properties are lost and become conductive, which is called breakdown. The voltage at breakdown is called breakdown voltage (dielectric strength). Electric strength is the quotient of the voltage when breakdown occurs under specified conditions and the distance between the two electrodes subjected to the applied voltage, that is, the breakdown voltage per unit thickness. For red fast paper insulation materials, generally the higher the value of breakdown voltage and electrical strength, the better.
