Part of Grendene's complex, is a complete laboratory for the development of PVC, where research on textures, densities and appropriate performances is executed for each type of product, searching for specific raw materials. Researchers in this laboratory have already developed more than 70 formulations of PVC. Another competitive edge for Grendene from competitors that use a single formulation for the production of their products regardless of fit, function or wearability. This complete control and development of raw material gives to Grendene a prime condition of having the specific requested material for each product.
