The roller or roll is stripped of all the old polyurethane, PU, or rubber covering.
Engineers carry out NDT (non destructive test), dimensional and visual checks on all aspects of the roller or roll.
Roller results falling outside agreed parameters (e.g. minimum roller stock diameter) are recorded.

The rollers or rolls are cleaned of any grease, dirt and debris INSIDE and OUT.

The majority of Bonaprene’s rollers or rolls are recovered using Bonaprene’s state of the art computer controlled polyurethane, PU, dispensing equipment. Bonaprene’s polyurethane dispensers have over 1000 litre capacity and guarantee a homogenous air and contamination free polyurethane recover. This gives uniform polyurethane properties not only throughout the roller or roll covering but from roller to roller.

Bonaprene has comprehensive small batch roller recovery facility. This allows the processing of a vast range of polyurethane and rubber compound and curative combinations. The major benefit of Bonaprene’s equipment is new. Bonaprene can offer the recovery of a large range of polyurethane & rubber roller compounds and hardness through different systems. The customer has a wide choice and improved roller finish quality.
