Raw materials

Exclusive raw materials in terms of quality, strength and durability

For the production of technical rubber items, we use high quality raw materials that guarantee resistant and long-lasting products. The choice of raw material varies depending on the specifications of the item to be made and the industrial need.

The production process is constantly monitored in accordance with the provisions of the Quality Management System. All products are subjected to rigorous controls in order to ensure perfect compliance with the customer's needs, before being marketed.

For their production, we select only exclusive raw materials in terms of quality, resistance and durability. Below you will find some of the most used which, depending on the type, may be available in different colors according to a RAL reference table.

VMQ
