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

 

Product features:

  • Good chemical resistance (including chlorine)
  • Hydrolysis resistance (hot water and steam)
  • Flame-retardant types available (ISO 340)
  • Some food types available (dry food)
  • Economically priced
  • Available in many different hardnesses, profiles and colours
     

Industries:

  • Airports
  • Logistics
  • Agriculture
  • Fruit and Vegetables
  • Marble and Ceramic

 

Nonex

 

Product features:

  • Good resistance to oil and fat
  • Food compliance for all foodstuff
  • Available in white and light blue, and with different profiles
     

Industries:

  • Food
  • Handling unpacked food

 

Arcon

 

Product features:

  • Abrasion Resistant (ISO 5470-1)
  • Compliance with EC and FDA
  • Flame retardant (ISO 340)
  • ATEX cat. 2 approved
  • Anti-static (ISO 21178)
  • Low elongation
  • Possible with sealed edges
  • Lightweight constructions
     

Typical application:

  • Transport of refined sugar or other
    granular products
  • Trough, horizontal or inclined
    conveyors 
  • Bucket elevators

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

 

Product features:

  • Belts with thermoplastic polyurethane coating
  • Very flexible even at low temperatures
  • Very good resistance to oil and fat
  • Good abrasion resistance

  • Ropanyl Premium Plus = Non-fray

Industries:

  • Food
  • Packaging
  • Wood
  • Textile
  • Metal

Industries:

  • Food
  • Tyre
  • Wood

 

Ropanol

 

Product features:

  • Belts with polyurethane impregnation (zero thickness)
  • Low friction top side for accumulation
  • Very flexible even at low temperatures

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

  • Pyrolysis resistance (non-toxic when burning, tobacco approved)
  • Good wear resistance
  • Very easy to clean
     

Industries:

  • Tobacco
  • Wood (lacquering)

 

Amtel

  • Tobacco
  • Food

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
