It is resistant to organic solvents and a variety of diluted acids and alkali.įor flammability and burning performance, Willtec complies with national and international regulations, and receives the highest rating possible for an organic material. Willtec is characterised by its ability to sustain high temperatures (>150☌), its low density (11kg/m 3), and its exceptionally good sound absorbing properties. Willtec can be used in all those places where normal or highly inflammable materials cannot be applied, and where mineral wools and impregnated foams, which have up to now been used, have to be replaced for weight reasons. Thus, out of the original brittle material, a soft elastic, membrane-free and completely open-celled foam is produced, which is suitable for numerous sound absorption applications. The foam structure consists of a spacious meshwork, the individual struts of which are extremely soft and flexible because they are thin. The high quality properties of this foam, which under normal conditions does not burn independently, are essentially due to its physical make-up. Willtec is a newly developed foam with a melamine resin base. All tiles have bevelled edges to allow fitting in any combination, always presenting a ‘finished’ edge face. The sculpted design is produced by cutting (rather than moulding) to ensure the front face is fully open-celled. Sound pressure waves are absorbed by the open cellular structure of the foam, and the contoured profiles provide the ability to trap waves at all angles of incidence, progressively weakening them as it bounces between the sides of the troughs in the surface. The complex shape of the profile leads to a smoother attenuation curve across the frequency spectrum, and a far greater absorptive surface than all conventional noise absorbing systems. The deeper the profile, the better the low and low-mid frequency absorption. It optimises absorption from all angles, the differing dimensions of the profile varying with different tile types for different applications, from extremely deep profiles for high performance wide-band studio work, to low cost shallow profile for machine noise reduction, where low frequencies are less significant. The sculpted tile profile have a complex design pattern is the main reason why Pinta outperforms other acoustic tiles.
