Abstract

Un procedimiento de fabricación de un material celular estanco rígido, caracterizado porque se mezclan íntimamente una resina a base de policloruro de vinilo, un isocianato, un anhídrido de ácido y la cantidad de un agente hinchador justamente necesaria para crear en la pasta pequeñas burbujas gaseosas uniformemente distribuidas y, eventualmente, otros productos tales como plastificantes, colorantes, estabilizadores, siendo inferior esta cantidad de agente hinchador a 5% en peso de la del policloruro de vinilo; se calienta a presión en un molde esta mezcla; después de enfriamiento del molde, se retira de él el cuerpo moldeado que se coloca entonces en una estufa a una temperatura comprendida entre 90 y 100º C en presencia de vapor de agua.
