Abstract:
La invencion brinda un material de limpiador absorbente de aceita facial adecuado para limpiar la piel o el cabello del usuario, y un metodo para su fabricacion. Los limpiadores comprenden al menos una pelicula co-extruida porosa absorbente de aceite facial de un material termoplastico cristalino con un diluyente solido que contiene una capa arrugable y una capa generalmente no pegajosa que es una capa microporosa de material termoplastico y un diluyente En general, el limpiador cambia su transparencia o color cuando se carga con aceite facial para brindar una funcion indicadora de la absorcion de aceite facial. El limpiador es capaz de formar una pelota compacta al arrugar una muestra de 10 cm x 10 cm hasta obtener un diametro de 3.0 cm o menos.

Abstract:
The invention is an extrusion device comprising an interleaving block portion. The interleaving block portion includes at least two first chambers, each first chamber including a width, a length, a height, and an input aperture. The length dimension of the first chambers are generally parallel. An output aperture is included in each first chamber, the output aperture is wider and shorter in height than the input aperture. A series of first distances are defined between the input aperture to points along the output aperture. A die portion is included in the extrusion device. The die portion has a laminate chamber having a height dimension. The height dimension of the laminate is disposed generally perpendicular to the length dimension of the first chambers. An output is disposed at one end of the height dimension. The laminate chamber is disposed so as to be in communication with the output apertures of the parallel first chambers.
Abstract:
Microporous articles are formed by solid-liquid phase separation from a diluent in combination with a thermoplastic polymer, flame retardant and a hindered amine synergist providing novel flame retardant articles. Such articles are useful in clothing, barriers, optical films in electronic devices (such as light reflective and dispersive films), printing substrates and electrical insulation.
Abstract:
Se forman articulos microporosos por separacion de fases solida-liquida de un diluyente en combinacion con un polimero termoplastico, retardador a la flama y un sinergista de amina impedida que proporciona nuevos articulos con retardador a la flama. Estos articulos son utiles en ropa, barreras, peliculas opticas en dispositivos opticas en dispositivos electronicos (tal como peliculas dispersivas y reflexivas de luz), sustratos de impresion y aislamiento electrico.

Abstract:
Microporous materials and articles are disclosed. The microporous materials contain a polyolefin or olefinic polymer and a solid diluent in which the polymer is soluble at a temperature above the melting temperature of the polymer and that phase separates from the polymer at a temperature below the polymer crystallization temperature. The resulting material is a microporous material having a polymeric matrix with solid diluent present throughout. The invention is also directed to methods of forming the microporous material using thermally induced phase separation and subsequent processing.
