Feature

1. The rollers coated with PFA sleeves

  1. By coating surface layer of the silicone rubber with escalope PFA sleeve, it can be used as rolls which excellent in releasability, heat resistance and durability.

  2. Soft fixing roller is superior in a thermal conductivity by using thin and high heat conductivity materials as rubber.

2.Backup roller (Auxiliary transfer roller)
By original rubber combination, a more stable electric property value is provided.
