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.
TPP castor wheels feature Thermoplastic Elastomer TPE tyres with plain bore which are normally only used for lighter loads that are moved less often over short distances.
Suitable for L series castors.
