main materials used in most membrane keypads:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-polyester-pet\">1.\u00a0<strong><strong><strong><strong><strong>Polyester (PET)<\/strong><\/strong><\/strong><\/strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Most Popular for Industrial Applications<\/strong><\/p>\n\n\n\n<ul
