Description

  • Suitable for rubber rollers with high requirements for rebound resilience and wear resistance, such as flooring industry and other applications in machinery industry.
  • Suitable for high temperature resistance or general solvent conditions, such as hot melt adhesive, small quantity of DOP and general weak acid and weak alkali conditions.
  • Suitable for the rubber layer of corona rubber rollers. Excellent arc resistance and super dielectric strength can increase the life of product. In plastic film packaging industry and double stretch film (BOPP, BOPET, BOPI) industry, corona machine and corona rubber roller complete the corona treatment of various plastic films.
