Particularly energetic, it has a strong germicidal power: by altering the DNA of micro-organisms (bacteria, viruses, molds, etc.), it effectively eliminates them. This property explains its widespread use in non-contact disinfection processes, now deployed in many critical environments. <\/p><\/div>\n\n\n\n<p>Traditionally emitted by low-pressure mercury lamps, UV-C radiation has undergone a technological revolution with the arrival of UV-C LEDs. These new sources offer unprecedented possibilities for integration into devices that are more compact, durable, energy-efficient and free of toxic substances. These developments open the way to numerous industrial applications, but also raise a new challenge: the resistance of polymer materials exposed to this artificial radiation.<\/p>\n<\/div><\/div><\/div>\n<\/details>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-e42438a is-style-plain\" data-block-id=\"e42438a\"><style>.stk-e42438a {border-style:solid !important;border-color:#dfdad1 !important;border-top-width:0px !important;border-right-width:0px !important;border-bottom-width:1px !important;border-left-width:0px !important;padding-bottom:24px !important;}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-5a62c07 stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"5a62c07\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5a62c07-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-5a62c07-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-b63dd24\" data-block-id=\"b63dd24\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-1c7f673\" id=\"uv-c-applications-in-all-industrial-sectors\" data-block-id=\"1c7f673\"><h2 class=\"stk-block-heading__text\">UV-C applications in all industrial sectors<\/h2><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-f10e508\" data-block-id=\"f10e508\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-f10e508\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-f-10-e-508-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-f-10-e-508-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-1268971 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"1268971\"><style>.stk-1268971-container{padding-top:0px !important;padding-right:0px !important;padding-bottom:0px !important;padding-left:0px !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-1268971-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-1268971-inner-blocks\">\n<div class=\"wp-block-stackable-text stk-block-text stk-block stk-4b7e43d\" data-block-id=\"4b7e43d\"><p class=\"stk-block-text__text\">The use of UV-C radiation now extends far beyond the medical field.

Their much higher photon energy causes molecular degradation on the surface, directly affecting the optical and aesthetic performance of plastics. These alterations, even when they remain superficial, can degrade the perceived quality, safety of use or even regulatory compliance of the final product. The main effects observed when exposed to UV-C are: <\/p><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Yellowing or discoloration of transparent or tinted plastics, altering their visual appearance. <\/li>\n\n\n\n<li>Loss of transparency (opacification), problematic in optical or medical applications. <\/li>\n\n\n\n<li>Surface cracks or micro-deterioration, with a potential impact on hygiene or chemical resistance. <\/li>\n\n\n\n<li>Ageing varies from one polymer to another, and is difficult to anticipate without specific tests. <\/li>\n<\/ul>\n\n\n\n<p>It is therefore essential
