The coatings used on Synthetic Belts are called polymers and can be made of various materials which have influence on the suitability of the belt in a certain application.
Polymers can be separated into two different groups: thermoplastic or thermoset.
Mainly used compounds for coatings are:
PVC | Polyurethane | Polyolefin | Polyester
Polyvinyl chloride, commonly abbreviated to PVC, is a widely produced plastic. PVC is a type of thermoplastic polymer that is flexible and durable, and therefore suitable for use on conveyor systems.

Polyurethane belts are mainly used in the Food Industry. Due to its structure, polyurethane belts do not give off damaging toxins or chemicals. Polyurethanes for process and conveyor belting can be either thermoplastic – TPU, or thermoset – PUR. Thermoplastic polyurethane coating material excels through its exceptional resistance to grease, oils and chemicals.
