Cleats and profiles for conveyor belts are mainly produced from two materials - SBR and NBR, the technical properties of which are outlined in the table below. As we have our own production of rubber materials, special compounds can be developed for customers with specific requirements.

MARKING
The type of material is denoted by letters in profile's part number: B=SBR, C=NBR.
The number after the letter stands for compound hardness: 6=60°ShA, 7=70°ShA.
