However, peroxide cured polymers are more suitable in alkaline environments or in contact with water and high temperature steam. At the other end of the table, we find Viton Extreme\u00ae (ETP) or FEPM fluoroelastomer according to ASTM. It presents the particularity of being resistant in highly alkaline solutions, steam and amines, but it is relatively little known in the market, due to its difficult processing.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-12359 alignleft\" src=\"https:\/\/epidor.com\/wp-content\/uploads\/2025\/04\/70-Las-diferentes-facetas-del-FKM-2020-07-22-INTERIOR.png\" alt=\"\" width=\"739\" height=\"312\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Variants<\/strong><\/p>\n<p>Articles made of FKM can be supplied with a wide variety of options or certificates: lubrication, PTFE coating, conductive, AED, USP, 3A, FDA, CE1935\/2004, KTW, NSF, detectable and in all colors (brown and black being the most common).<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div id=\"pgc-12352-0-2\"  class=\"panel-grid-cell panel-grid-cell-empty\"  data-weight=\"0.05\" ><\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>&nbsp; Fluoroelast\u00f3mero, FKM, FPM, Viton\u00ae\u2026 solo con el nombre, cuya referencia comercial se ha impuesto m\u00e1s que la denominaci\u00f3n oficial, ya es un l\u00edo, as\u00ed que hemos decidido escribir una peque\u00f1a gu\u00eda did\u00e1ctica sobre este material tan habitual en nuestros mercados: Primero, pongamos un poco de orden con la nomenclatura: Fluoroelast\u00f3mero: se trata de un [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":2979,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[41],"tags":[],"class_list":["post-2976","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-informacion-tecnica"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 -
