Tailor-made for each process step
The rollers have to maintain their dimensional and chemical stability, their hardness and surface characteristics throughout a wide range of temperatures and chemical environments. When squeezing off excess liquid after degreasing or other baths, they have to be hard enough to achieve a good and even result, but soft and pliable enough not to damage or mark the aluminium strip itself, even when processing foils only a few microns thick! Chemical resistance of the roller material against eolling oils, coatings, etc. is another high-priority demand, as are surfaces which are at the same time finely structured and mechanically robust, in order not to be damaged by the material running over them. Böttcher has developed a broad range of specialised rubber and polyurethanroller material to meet these diverse demands. Every one of them was developed in our central R & D laboratories in Cologne, Germany and all rubber compounds are manufactured in our own, state-of-the-art rubber compounding plant. Made by us for you, to make it easier for you to meet the challenges the marketplace and your customers place on you.
Longevity
- Very good mechanical resistance to edge marking, cutting and tearing
- High dimensional, durometer and surface stability - important when processing thin materials
- Less downtime and lower maintenance cost
Optimum material for each process step
- Durometers from 65 to 95 Shore A (for coating applications from 40 Shore A)
- Temperature resistance up to 200°C - or more if required
- Excellent resistance to oils and other chemicals
Stability and process security at the highest production speeds
- Dimensional and durometer stability, even in extreme conditions
- High vibration damping properties at high speeds and older machinery - no "dancing" rollers
