Special Synthetic Conveyor Belts
Special conveyor belts are designed for the transport of material or objects of various kinds with specific requirements for their properties, which cannot be met by belts made of common materials.
Main Types of Belt Materials
“Special blends” are mainly created by mixing different variations of PVC or polyurethane.
The main types of special materials are:
Special thermostable silicone belts with high chemical resistance and very high temperature resistance. They have a non-stick surface and high adhesion at the same time.
Special belts made of thermoplastic compound with low hardness for applications requiring high adhesion.
Special belts made of a compound of rubber and PVC combining the excellent mechanical properties of PVC with wear resistance of rubber. They are also resistant to fats and oils.
Special belts made of a compound of rubber and thermoplastic combining the excellent mechanical properties of thermoplastic with rubber wear resistance. They have an adhesive surface and are resistant to oils.
Special belts made of a mixture of thermoplastic with high non-stick surface, resistance to oils and greases and high chemical resistance.
Special belts made of a compound of thermoplastic with a non-stick surface, resistance to hydrolysis, resistance to oils and greases. They are flexible and suitable for high temperatures.
The base of the belt is made of a fabric, which is coated on the top and bottom with a “special blend” of polymers manufactured by Ammeraal Beltech. These are, for example, blends called SILAM, PLETEX, ELASTOFLEX, ELASTONYL, ULTRACLEAN or ULTRANYL.
The belt consists of one or more layers that ensure its strength, stability and cut resistance.
- Bottom cover layer
- Inner layer
- Top cover layer
Belts Fields of Use
SILAM conveyor belts are designed for use mainly in the food industry or in the rubber industry.
PLETEX and ELASTONYL conveyor belts are designed for use mainly in the paper and printing industries.
ELASTOFLEX conveyor belts are also designed for the paper and printing industries, but are also used in the woodworking industry.
ULTRACLEAN and ULTRANYL conveyor belts are designed for use mainly in the food industry, e.g. ULTRACLEAN for working with adhesive products.

Additional information, characteristics:
Joints can be made depending on the material of which the particular belt is made. You will find the exact information in the technical documentation of the selected belt.
Simple Finger Splice
A simple punched splice, that is joined into an endless belt by heat on a splicing machine. It is performed on belts with one fabric layer.
Double Finger Splice
Combined splice. First the belt must be separated into individual layers, which are then prepared separately for splicing. On the splicing machine, the layers are subsequently joined into an endless belt by heat. It is performed on multilayer belts.
Anker A Wire Hooks
Wide range for use in all operations from packaging lines, pharmaceutical industry, food industry, laundries. These are the most used connectors for PVC belts.
Anker G Lacing
Basic connection with lower strength, for which no installation jig is required. Ideal for undemanding joints. It is used especially by customers who do not connect belts too often.
Alligator RS – Ready Set
Easy installation, good strength and possible to use for pulleys with small diameters. Ideal for sorting lines, applications in agriculture, etc.
In addition to the above-mentioned most common types, it is possible to connect belts by other methods according to the requirements of the specific application. Our specialists will be happy to provide you with more information.
Belts Surface Structure
The surface structure ensures the specific properties of the belt. Applications range from easy separation of the product from the belt to the use of surface adhesion in technological processes or for inclined transport.
The surface structures can be on the top or bottom cover layer. The choice of structure depends on the properties of the transported product.
There are many types of structures in the product range. The most common can be found in the Overview of Standard Surface Profiles (PDF file for download).
Guide profiles ensure direct belt guidance and prevent belt movement on the rollers. The result is a smooth guidance without a polygon effect, which is also suitable for higher speeds.
Profiles made of PVC, polyurethane or polyester are welded or glued to the bottom side of the conveyor belt.
The V-profile can also be used as a transverse carrier or side edge for transporting material.
The most common way of guiding the belt is a V-guide.
The smooth, clean design of the wedge is less prone to contamination.
On the bottom side of the belt there is a wedge with pressed teeth, which allow easier bending and thus smaller cylinder diameters than solid wedges.
In addition to the V-profiles, the guide profiles can also be square. However, their use is far from numerous. If you are interested in implementing square guide profiles, please contact us.
BORDOFLEX side walls made of PVC or polyurethane are welded on the sides to the top of the belt.
Side walls are used for the transport of bulk materials and for the transport of material at an angle. They prevent spillage or loss of materials.
Transverse cleats made of PVC, polyurethane or polyester on top of a belt for inclined/declined transport. They prevent the material from sliding or falling.
The possibilities of their shapes and fastening are wide and are based on the used material of the belt, as well as on the requirements for optimizing the function of transporting the material or objects.
Additional Belts Modifications
Punching of conveyor belts is performed for the transport of products using vacuum and for applications with photocell control.
Punching is performed on punching machines, which are able to produce punching in a precisely defined arrangement.
AMSEAL Sealed Edges
The AMSEAL sealed edge system guarantees reliable protection of the belt edges. It prevents fraying and thus prevents the penetration of bacteria, oils and fats into the belt structure.
The AMSEAL edge protection completely seals the edge of the belt with a thermoplastic strip. It increases the safety and hygiene of food production, increases the life of the belt and enables easy cleaning.
It is most often used in the food industry, processing of meat, fish, fruit, milk and other foods, in bakeries and other operations.
