Abstract

Se trata de composiciones selladoras y capas selladoras con características de termosellado de fácil desprendimiento. La composicion y capaselladora se preparan a partir de por lo menos un polímero de etileno, por lo menos 25% en peso (en base al peso total de la composicion o capa) de porlo menos un polímero de polibutileno, un aditivo con contenido de sílice o calcio, un aditivo de deslizamiento y cantidades opcionales de un polímero deetileno como resina de vehículo aditivo. El polímero de etileno preferido es un polímero de etileno homogéneamente ramificado y el polímero depolibutileno tiene una baja cristalinidad o alto contenido de comonomero. Como una capa selladora, la composicion tiene propiedades de adherenciaal calor excelentes,bajo coeficiente relativo de friccion y especialmente propiedades excepcionales de sellado, en donde su resistencia de sellado porcalor es del orden de 0,27 a 0,64 kg/cm de amplitud a 100*C y la desviacion promedio estadística de su resistencia de sellado por calor a temperaturasde sellado de 100* a 130*C es menor o igual al 16,5%. La composicion es util en aplicaciones que requieren consistencia y rendimiento de selladodesprendible estable a través de ventanas de sellado amplias, tales como, por ejemplo, revestimiento internos para cajas de cereales. También seproponen los objetos mencionados en el título.
