Two-component solid rubber: Tread material for castors & wheels
As an alternative to solid rubber, castors and wheels or tyres can be produced with a tread made of two-component solid rubber. This tread combines a harder rubber with a softer rubber.
The harder rubber component forms the core of the tyre. The softer component is vulcanised on top of this. In this way, the properties of the different types of rubber are combined with each other. The softer component is usually highly elastic to reduce the starting and rolling resistance.
Properties of tread
Treads made of two-component solid rubber offer an ideal combination of running smoothness and low rolling resistance. The harder component also ensures a high load capacity. The tyres are floor-friendly and dampen vibrations. They also have good resistance to many chemical substances. and can be used at temperatures between approximately -30 °C and +80 °C. Driving comfort is significantly better than with the solid rubber versions. This means that these tyres can be used in a wide range of applications where solid rubber tyres are not suitable.
