- Polycotton fabric frictioned with Polychloroprene rubber.
- Cushion rubber to stretch at the belt bend.
- Tension member to carry power and minimise stretch.
- Base rubber to support cords evenly and compress as the belt bends.
- Improved transmission ratio (Poly-V 1:60 vs. V-belt 1:20)
- Reduced diameters can be used.
- Reverse bend application.
- Reduced belt width for a given geometry and similar power transfer.
- Provide a wide selection of speed ranges.
