he raw materials, which are placed in their relative production tanks, are dosed with other additives carefully selected inside the mixing top in which the reaction start takes place. The process occurs without using damaging substances for the environment: complementary agents, like CFC and METHYLENE CHLORIDE, are excluded from the production process both because they’re not compatible with the environmental protection and because they are harmful for the security and health of the final users.

From the mixing top the foam arrives in a tank from which it overflows then on a conveyor belt that goes through a tunnel, which is kept under strong aspiration. The reactions of expansion and polymerization develop in about 1/3 minutes; during this interval time the block achieves the final dimensions. Once that the block gets out from the tunnel, it is cut into variable length boards, which are sent in a maturation system.

The completion of the polyurethane reaction is obtained in a period of time between 24 and 72 hours from the mixing of the components, later the boards are stored into warehouses.

After that, the polyurethane block is picked up in order to be submitted to further cutting operations. 

Thanks to VPF (Variable Pressure Foaming) System, an innovative foaming method, we have been able to improve our production processes.

Our technology is mainly based on vacuum and pressure foaming process variables. This prevents from using external uncontrollable agents (such as CFC/HCFC, Methylene Chloride, CO2…) obtaining expanded material using water only, completely environmentally friendly and recyclable. The chambers of VPF system can be considered as closed reactors where the pressure can be constantly fixed and controlled.

VPF gives the possibility to obtain a wider range of products, creating new foams with improved properties.

Among the different qualities of VPF method, the high environmental compatibility is to be mentioned. The tunnel in which this process takes place is completely closed and the gases generated during the foaming reaction are collected inside the plant and are cleaned by active coal filters before being released in the atmosphere.
