Standard Materials for modular plastic conveyor belts

All belts from ScanBelt are naturally available in the traditional materials; Polyethylene (PE), Polypropylene (PP) and Polyacetal (POM).

All standard materials are FDA approved for direct food contact.

Polyethylene can handle operational temperatures down to ÷73° C and is thus suitable for installations in cold areas. It will also be ideal for applications that require a flexible belt material with superior impact strength.

Polypropylene can handle operational temperatures up to 100° C. It is a harder material with a good pulling force. It is suitable for installations in high range temperature areas as well as boilers and dryers to a certain degree. It has excellent chemical resistance towards aggressive cleaning chemicals etc.

Polyacetal is a strong all-round material with a working temperature from ÷43° to +95°. This material has great pulling force and a hard surface, which gives a reduced friction to both the support and the product. It is sensitive to blows or knocks due to low impact strength. Suitable for bottling and canning industry. Should be used with caution in installations that use cleaning agents containing acid and/or chlorine.

Special Materials for modular plastic conveyor belts

In order to solve tasks out of the ordinary, we are able to deliver a variety of special materials as well as additives.

High Temperature Areas

For cookers, steamers and air dryers etc. it will be an advantage to use a temperature stabilised polypropylene material that is not affected by a constant high temperature. 

For blanchers and pasteurizers etc. where the belt’s thermal expansion may be an issue, we supply belts in COMPOSITE MATERIAL. This reduces the thermal expansion coefficient by approx. 75% from normal polypropylene. Furthermore, it has excellent chemical resistance and will help dissipate static charges that might build up in certain applications.

For more general applications in high temperature areas, we recommend various nylon types, which will give a great combination of pulling force and high impact strength.

Nylon

Nylon can be used in both warm and cold areas as it handles temperatures ranging from -45° to 160° (depending on the choice of nylon). It is a soft material with a good pulling force. It has a high impact strength as well as a decent chemical resistance.  Density ranges from 1.08 to 1.37. We use standard Nylon, Nylon 6 glassreinforced, Nylon 6.6, Nylon 6.6 glass-reinforced, Akulon Nylon. The Nylon 6 types are FDA approved. Note that not all our belt types are offered in Nylon.

Reinforced Materials

In areas with distinct necessity for added pulling force, we can supply either fibre or mineral reinforced materials. These will improve the pulling force significantly, but at the same time lower the impact strength.

Electrical Conductivity

Most materials can be delivered either as electrically conductive or antistatic. The electrical conductivity can be varied to suit your requirements.

Non-stick
 

There is often a need for ”non-stick” effect; particularly for freezing applications where it is necessary to avoid the products sticking to the belt surface. For this purpose, we deliver
polyethylene in a non-stick version.

Detectable Polypropylene
 

The material is highly relevant in food applications where there is a risk of contamination. The compound is designed to be detected by metal detectors and X-ray machines. Sensibility
degrees may vary with customer’s equipment. The material complies with FDA regulations for use in food processing and packaging.

Flame Retardant Materials

For use in fire hazardous areas, we can supply V-0 rated materials that will not sustain a flame or burn actively.

Cut resistant POM

The Cut Resistant POM has an improved cut resistance compared to the regular POM and PP materials. It has a superior abrasion resistance and a better impact strength than regular POM materials and it is highly rigid while maintaining pulling force and surface hardness. It also has a low coefficient of friction.

The Cut Resistant POM is offered in the S.25-800 S-L and S.50-808 S-L Flat top series. It is available in POM/Blue for both types.
