An extensive range of rubber covered rollers are used throughout the paper making process.These rollers are primarily used in the de-watering, sizing, drying and calendaring processes, requiring a range of rubber compounds to provide chemical, temperature, abrasion and co-efficient of friction resistance properties along with hardness stability, dynamic properties, heat stability and low co-efficient of thermal expansion characteristics.
