The management of this waste, recycling difficult, as a by-product is an environmental improvement

Polyurethane is a type of polymer that can be classified into two groups depending on their chemical structure: sign foam thermoset polyurethanes and thermoplastic polyurethanes. Polyurethanes are the most common thermosetting polyurethane foams widely used as industrial insulation.
The polyurethane foam is obtained from the reaction between isocyanates and polyols in the presence of additives and catalysts. Once mixed components, the reaction heat released is used to vaporize the expansion agent that is causing the transformation of the mixture into a foam. Due to its low coefficient of heat transfer is widely used for insulation components for automobiles, mattresses and insulating sign foam pipes, among other uses.
One way of mechanically recycled polyurethane foam is compression molding. In this technique, sign foam perfect in automobile applications, polyurethane foam is milled into fine particles and subjected to pressures and temperatures for optimal power generating new material, while maintaining the original properties. This type of molding allows use in thermoset materials such as polyurethane foam after grinding. sign foam
In this case the product comes from polyurethane foam manufacturing modeling for car seats and backs. For the manufacture of these modeling Foam Manufacturing Company prose injected into the corresponding aluminum molds hot (in closed hot water) components to form the polyurethane foam with appropriate insertions (steel rods reinforcements fabric ..) previously placed. Once the components react Just unmold parts. Those parts that do not meet the quality criteria set become waste, the company sign foam manages as a byproduct.
The residue of polyurethane foam uses a company dedicated to the manufacture of thermoformed parts for automobile interior soundproofing. Once the company sign foam receiving the polyurethane foam is crushed with grinders with emborrats for textile pieces, which warped by heat and pressure by the thermoforming process. These pieces are installed in vehicles for soundproofing and thermal noise.
The management of this waste, recycling difficult, as a by-product is an environmental improvement because it reuses waste avoiding sign foam that ends in a landfill and reduce CO 2 emissions resulting from the manufacture of virgin foam . It also involves economic advantages for both producer and recipient, the company producing the waste management costs saved this in a landfill and the company receiving the money saved from having to buy virgin polyurethane foam .
