Coating Materials
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
PVC
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.
Main PVC coating types:
Flexam

Polyurethane
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.
Main polyurethane coating types:
Ropanyl

Polyolefin & Polyester
Polyolefins are the largest group of thermoplastics; they are polymers of simple olefins such as ethylene. Polyethylene is probably the polymer you see most in daily life; it is the most popular plastic in the world.
Main polyethylene coating types are:
Peflex

Industries:
Fabric & Felt
Fabric and Felt belts are used in a wide variety of material transport applications such as car manufacturing, food processing and heavy industry. Felt is a non-woven fabric. The most important raw material for belting fabrics is polyester.
Main fabrics used:
- Cotton (natural)
- Flax (natural)
- Polyamide (synthetic)
- Polyester (synthetic)
Specials
By mixing polymers together, Ammeraal Beltech produces variations on PVC or PU called “Special Blends”. E.g.:
- Pletex (red): a special thermoplastic low hardness polyblend for high grip applications
- Elastoflex: a rubber / PVC compound which combines the excellent mechanical properties of PVC with the wear resistant characteristics of rubber
- Elastonyl: a rubber / TPU compound which combines the excellent mechanical properties of TPU with the wear resistant characteristics of rubber
- Ultraclean: a special compound of TPU with a high tech polymer with superior release properties
