73 Polypropylene wheels are an inexpensive alternative to polyamide areas of use// floors The material polypropylene (PP) is a low-cost alternative to polyamide. It also features a lower specific weight and does not absorbs moisture. Polypropylene is resistant to salt water, as well as many acids and alkalis up to a certain concentration. Properties excellent chemical resistance high load capacity resistant to fracturing even at heavy loads long working life run well on smooth floor surfaces low rolling resistance Shore hardness approx. 60° Shore D Temperature range polypropylene can be used from 5° C to 80° C the load-carry capacity is reduced at temperatures above +30° C Bearing types plain bearing (through hole) roller bearing ball bearing polypropylene // profile solid & smooth/ at soft & sensitive
