Cork, the bark of the cork oak tree, is a material with unique properties and used in several applications. In a perspective to take advantage of this noble material, the industry has developed products that use granulated material for which specific agglomerants are necessary. In this context, polyurethane appears as the main agglomerant for cork, given the versatility of this polymer at the level of mechanical properties, which allows its use in various processes and products.
The cork agglomeration industry constituted the first market of action of FLEXPUR face to its strategic localization in relation to some operators of reference in the sector. The close relationship with the customers and a continued focus on the study of the relationship and synergy between the cork and the polyurethane have allowed the development of varied solutions for each one of the areas of cork in which polyurethane products are used.
