The rubbers used in making the tyres for our castor wheels include Thermoplastic elastomer (TPE) and Hi-res blue rubber. Rubbers, as the name suggests, are softer bouncier materials that incorporate additives and properties to improve wear, reduce flat spotting and make them non-marking. Softer tyred wheels are quiet rolling over rough and eneven surfaces, however their ability to carry heavier loads is reduced somewhat according to the hardness and resilience.
BPB castor wheels feature a bouncy high resilience blue rubber compound that is quiet, impact absorbing and non-marking which also returns some of the energy (bounce) that helps lower the rolling resistance when loaded to its correct capacity.
Suitable for J2 series castors.
