Abstract

LA INVENCION SE REFIERE A PLACAS DE ESPUMA EN FORMA DE BANDA DE POLIOLEFINAS, QUE SON FABRICABLES A PARTIR DE MASAS DE FORMA DE POLIOLEFINA QUE CONTIENEN FERMENTOS MEDIANTE PROCESOS DE EXTRUSION, ESPUMACION Y EXPANSION DE ESTAS MASAS Y DONDE SE UTILIZA EN SU ELABORACION HIDROCARBUROS LIBRES DE HALOGENO Y/O CO2 COMO MEDIO IMPULSOR. LAS PLACAS DE ESPUMA DE ACUERDO CON LA INVENCION MUESTRAN DE FORMA DIRECTA DESPUES DE SU ELABORACION, SIN ENVEJECIMIENTO ADICIONAL, UN CONTENIDO EN MEDIO IMPULSOR MAS BAJO DEL 30 %, EN COMPARACION CON LOS PRODUCTOS HASTA AHORA CONOCIDOS DE IGUAL TIPO DE FABRICACION. LAS NUEVAS PLACAS DE ESPUMA DE ACUERDO CON LA INVENCION SE CARACTERIZAN, PORQUE LA SUPERFICIE DE LA PLACA PUEDE SER PERFORADA POR UNA AGUJA DENTRO DE UN MAXIMO DE TRES HORAS DESPUES DE LA EXTRUSION. TIENEN UNA ESTABILIDAD TERMICA MUY BUENA. LA ELABORACION DE LAS PLACAS DE ESPUMA DE ACUERDO CON LA INVENCION SE CONSIGUE SEGUN LOS PROCESOS HASTA AHORA CONOCIDOS SOBRE DISPOSITIVOS CONOCIDOS. DE ACUERDO CONLA INVENCION EL PRODUCTO ES PERFORADO POR AGUJA ADICIONALMENTE DE FORMA INMEDIATA, UNA VEZ QUE HA OBTENIDO SU RESISTENCIA PROPIA DESPUES DE LA EXTRUSION.
