CONVEYING APPLICATIONS
Among all synthetic materials and rubber compounds, polyurethane is the material which offers the best resistance to abrasion.
Polyurethane films of different thickness and different shore hardness, applied on ELATECH ® belts, are an ideal solution in many appli-
cations in the wood processing, ceramic and glass industry. On request it is possible to supply polyurethane backings FDA approved.
Polyurethane foams are easily compressible according to the cellular structure of the material. Due to this main characteristic,
common applications are: labelling equipment, light and/or fragile materials conveying, glass and paper industry, vacuum conveyors.
