Reduce wrinkles occurring on the nip roll and feed roller and damages on the base material and improve the peeling performance by lowering the surface energy of a rubber roll.
The durability of rubber can be decreased by forcibly deteriorating rubber (surface modification by chlorine) in the conventional surface modification method for rubber rolls. We have established non-chlorine modification of NP-1 to modify the surface of a rubber roll, which improves the durability of rubber and is friendly to the environment.
| Not modified | Modified | |
|---|---|---|
| Hardness | 58-62° | 58-62° | 
| Surface Roughness | Ra:0.390 μm | Ra:0.332 μm | 
| Friction Coefficient | 1.6 | 0.31 | 
 
To examine effects of the substance eluted from EPDM rubber on the opponent material (film), measure the surface energy of a film by contacting the film onto the rubber surface before and after modification.
