A flame-retardant, PXX (self-extinguishing material) version is available for the automotive industry.
The S17-0 FLT variant now comes in light gray polyoxymethylene/polyacetal (POM) and blue polypropylene (PP).
Polybutylene terephthalate (PBT) hinge pins are available for belts made of POM and PP hinge pins for PP belts. The unique keyhole pin retention system makes the hinge pins very easy to remove and fit. This is an enormous advantage, especially in the case of wide belts requiring more than one hinge pin.
