Resumen

Procedure for obtaining a protective polymer mask for non-invasive ventilation systems. The method provides a protective mask for non-invasive ventilation systems from a polymeric gel, easily moldable to achieve the mask, the method including a step of obtaining a dry polymer mixture and a second step of obtaining a wet mixture from the first dry mix, using for the first stage a dry blend of a first solid polymeric material which is a thermoplastic elastomer based on styrene and ethylene/butylene, a second stabilizing solid polymeric material which is a thermoplastic elastomer based on styrene and a solid synthetic antioxidant ; and where a medicinal grade white oil is used for the second stage. The process includes a hot melt step to obtain the final protective mask. (Machine-translation by Google Translate, not legally binding)
