Caracter\u00edsticas principales del Mylar con l\u00e1mina de aluminio: 1) Excelentes propiedades de barrera. El Mylar con l\u00e1mina de aluminio presenta excelentes propiedades de barrera, ya que bloquea eficazmente la humedad, el ox\u00edgeno, la luz y las ondas electromagn\u00e9ticas.<br \/>\n2) Alta resistencia y durabilidad: La incorporaci\u00f3n de una pel\u00edcula de poli\u00e9ster mejora la resistencia mec\u00e1nica del Mylar de papel de aluminio, lo que le permite soportar ciertos niveles de estiramiento y desgarro.<br \/>\n3) Ligero y f\u00e1cil de procesar: el Mylar de papel de aluminio es ligero, lo que facilita su transporte y procesamiento.<br \/>\n4) Conductividad el\u00e9ctrica y prestaciones de blindaje electromagn\u00e9tico: La conductividad el\u00e9ctrica del papel de aluminio hace que se utilice ampliamente en la industria electr\u00f3nica para el blindaje electromagn\u00e9tico, protegiendo los equipos sensibles de las interferencias.<\/p>\n<p>II. La orientaci\u00f3n (hacia dentro o hacia fuera) de la capa de blindaje de papel de aluminio del cable influye directamente en su eficacia como blindaje electromagn\u00e9tico:<br \/>\n1) Cuando est\u00e1 orientada hacia el interior, el papel de aluminio entra en contacto directo con el n\u00facleo de alambre, absorbiendo la energ\u00eda del campo el\u00e9ctrico de la superficie del conductor mediante el efecto de carga de imagen, lo que reduce la radiaci\u00f3n de campo cercano en 10-15 dB.<br \/>\n2) Cuando est\u00e1 orientada hacia el exterior, la l\u00e1mina de aluminio act\u00faa como primera capa de blindaje, con una reflectividad superior a 90%, lo que mejora la atenuaci\u00f3n de las interferencias del campo magn\u00e9tico externo entre 20% y 30%.<br \/>\n3) Se recomienda la orientaci\u00f3n hacia el interior: situaciones en las que la frecuencia de la se\u00f1al sea superior a 1 GHz y se requiera un control estricto de las emisiones radiadas (como en el caso de las normas de compatibilidad electromagn\u00e9tica de clase B).<br \/>\n4) Es preferible orientarlo hacia el exterior: en situaciones en las que haya fuertes interferencias externas (como una intensidad de campo el\u00e9ctrico de 10 kV\/m), se produzcan flexiones frecuentes o sea necesaria la conexi\u00f3n a tierra.<br \/>\n5) Blindaje compuesto: cuando los requisitos de compatibilidad electromagn\u00e9tica (CEM) son estrictos, se utiliza una estructura de doble capa compuesta por \u201cuna l\u00e1mina de aluminio interior + un trenzado de cobre exterior\u201d, con una eficacia de blindaje &gt;120 dB (1 GHz).<\/p>","protected":false},"excerpt":{"rendered":"<p>Aluminum foil Mylar is a composite material consisting of aluminum foil and polyester film (Mylar).
