Fluororesin-Coated Rolls FST Roll
Elastic rubber rolls coated with fluororesin, heat-shrinkable tubes used in our original manufacturing technology enables adhesion processing of base materials and fluororesin at the same time as shrinking processing. Accordingly, “distortion”, “wrinkle”, “gap” can be eliminated on the roll even when shrinking-processed.
Application
- Olefin sheeting roll
- Laminating roll
- AC agent coating backup roll
Features
■Excellent mold releasability
Base material (rubber/metal) coated with fluororesin (PFA or FEP) is excellent in mold release effect, preventing adhesion of viscous material, resin, etc. Shows excellent mold release effect for molten olefin.
■Elastic rubber rolls coated with fluororesin, heat-shrinkable tubes.
Our original manufacturing technology enables adhesion processing of base materials and fluororesin at the same time as shrinking processing. Accordingly, “distortion”, “wrinkle”, “gap” can be eliminated on the roll even when shrinking-processed.
■Excellent solvent resistance
Fluorine resin has an excellent resistance to almost all solvents, so there is no swelling problem as found in general rubber rolls.
■Precision polishing available
Polishing equivalent to general elastic rolls is possible.
■Conductive type also available.
The volume resistivity of the roll is 1.0×107Ω・cm or less.
