Causes
- No sufficient heat conduction due to roll coating
- Insulation due to non-thermally conductive cover fabric
Effects
- Temperature on roll surface too high
- Chilling / heating capacity insufficient
- Process cannot be controlled exactly
Elastomer coatings basically have very poor thermal conductivity and have a correspondingly insulating effect in the process.
Thermally conductive materials enable heat to be transported in the desired direction through the roll coating. Production parameters can be controlled in a targeted manner and processes can be run more precisely and efficiently. The cooling and heating rolls used in numerous applications can thus be used effectively and provided with an elastic roll coating.
In many processes, a high thermal conductivity of the roll coating and thus a good cooling or heating performance is of decisive advantage.
