The tread of the TPA series is made of high-quality thermoplastic rubber with a hardness of 85 Shore A. This non-marking material is cast onto the high-quality polypropylene wheel centre and forms a strong chemical bond. The TPA series is characterised by very low rolling and swivel resistance. The castors in the series are also available in an electrically conductive version.
The TPA series is frequently used in the food industry or pharmaceuticals industry.
