Plastic materials for transport and conveyor systems
Plastics are commonly used in all areas of machine manufacture. The conveyor industry is an excellent example of this.
Conveyors are used in various fields, including the energy, forest, food and brewing industries.
In the energy and forest industries, they are utilised to transport coal, ash, wood, wood chips and pellets. Involving high mechanical loads and temperatures ranging from -40 °C to 60 °C, the conditions are demanding.
Overall, conditions in the food and beverage industries are not as challenging, but, on the other hand, line speeds are high.

The most commonly used conveyor materials and their characteristics
A pure, unmixed ultra-high-molecular-weight polyethylene. PE 1000 is a pure polyethylene with the lowest coefficient of friction, the greatest impact strength and wear‑resistance, and the best dimensional accuracy of all the polyethylene plastics. It is an ideal choice for applications that require good wear-resistance properties and a low coefficient of friction.
Excellent wear-resistance, good sliding characteristics, a low coefficient of friction, good resistance to chemicals, no absorption of water, easy machining, and good tensile and impact strength.
Off-white, black, and green
PE 1000 R (reprocessed)
Ultra-high-molecular-weight polyethylene. Made mainly from recycled material. Made mainly from recycled material, PE 1000 R is more cost-efficient than pure PE 1000 plastic. However, it is slightly less wear-resistant than the pure form of the material.
Excellent resistance to wear, good sliding‑ and abrasion‑related properties, good mechanical properties and cost-efficiency.
A polyethylene that has undergone further processing. Because of the molybdenum disulphide (MoS2) added to it, this material has enhanced wear‑resistance properties. It is recommended for applications entailing extensive wear.
Good ability to withstand mechanical loads, better-than-average wear resistance, better-than-average sliding-related characteristics, high tensile and impact strength and good resistance to chemicals.
Ultra-high-molecular-weight polyethylene. The material is specifically designed for environments with an explosive atmosphere that require ATEX certification.
Good resistance to wear, high tensile and impact strength, and good chemical resistance.
Electrically conductive. The material has been approved by TÜV Nord (Test Record No. YEX 550794).
A cast polyamide that contains oil as a lubricant. Because of its oil content, the material’s coefficient of friction is up to 50% lower and its wear‑resistance about five times greater than that of standard polyamides. This polyamide is best suited to applications in which the material is subjected to continuous wear.
Self-lubrication (with excellent wear resistance), a low coefficient of friction, good elongation‑related and impact‑resistance properties, good dimensional accuracy, and excellent sliding characteristics.
