Polyurethane is a material highly resistant to tension and compression. However, we must be careful because polyurethanes are NOT all the same, there are many types and formules of this product, designed for a diferent uses, with different values of strength and tensile strength and surface hardness (very important for durability), there are some with plastic touch wears quickly, whereas others are very rigid and split easily. PSYCO ART HOLDS have, thanks to their joint work with one of the largest European manufacturer of polyurethane, a formulation SINGLE & EXCLUSIVE*, based on hybrid polymers**, thinking only of the features must have a climbing hold. With this formulation, we have made the rock tact equal in typical old resin holds with mineral fillers, making it impossible to differentiate once bolted to the wall, but also achieving a surface hardness, twice, prolonging life thereof. *The Europur Material is produced only for our Factory, and only the members of Euro-holds group take benefit of this formula (www.euro-holds.com) ** The new technology EUROPUR, based on hybrid polymers, is incredibly harder and more resistant to abrasion than ever. @psycoartholds @hitoholds @rokodromo_climbingholds @3aholds @loopwear_climbing_and_holds @levierholds @alamo_wood_climbing #daiholds #climbing #climbingholds #europur #euroholds
