Material, as well as a method for the production of noise -, floating protectionists, otoplastics and for securing ventings

摘要

In order to obtain a material for the production of enables precise and for securing ventings to make available and simple production and post-processing, it is proposed that the material is made of at least a diisocyanate and at least one hydroxyl compound having at least two oh - groups, such that pre-hardening of the material by diisocyanate - polyaddition and final hardening takes place by means of radical polymerisation.
