PRODUCTION PROCESS FOR FOAM PLASTICS

摘要

The known styrene solutions of unsaturated polyester resins are not suitable for foam-product making, since the styrene always considerably lowers the stability of the foam. Besides this, in the foaming the styrenes to a considerable extent evaporate, and on account of this there are created unsanitary conditions for the work.nFor the purpose of increasing the stability of the foam and im-TD-TT-65-1247/1+4 proving the sanitary conditions of the work there is proposed a method for obtaining the foam plastics in which the polyester rnaleate resins are taken in the form of solvents of them in di- and polyester acrylate.
