In particular, PA66 with 25% fibreglass (PA66-GF25) is the ideal choice for the manufacture of thermal bridge break profiles. This contributes to energy efficiency in buildings.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Key properties of PA66-GF25 as a thermal insulator:<\/strong><\/h2>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li><strong>Low thermal transmittance value: <\/strong>PA66-GF25 improves energy efficiency by reducing heat losses.<\/li>\n<\/ul>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li><strong>High thermal resistance: <\/strong>able to withstand temperatures up to 220\u00b0C, higher than those required during the lacquering process.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Dimensional accuracy: <\/strong>the PA66 process allows for high precision in the final products, ensuring consistent quality in every part.<\/li>\n<\/ul>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li><strong>Fibreglass reinforcement: <\/strong>25% fibreglass reinforces the polyamide structure, improving its mechanical performance and ensuring higher durability.<\/li>\n<\/ul>\n\n\n\n<p class=\"extendedwopts-md-justify \">Thanks to these properties, STAC products made of PA66-GF25 ensure outstanding performance in terms of thermal insulation, contributing to both energy efficiency and comfort in buildings.<\/p>\n\n\n\n<h2 class=\"extendedwopts-md-justify wp-block-heading\"><strong>Additional features of PA66-GF25<\/strong><\/h2>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li>Thermal expansion coefficient close to that of aluminium, ensuring compatibility with other materials.<\/li>\n<\/ul>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li>Resistance to UV radiation, corrosion and ageing.<\/li>\n<\/ul>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li>Recyclable, contributing to sustainability.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The impact of moisture on PA66<\/strong><\/h2>\n\n\n\n<p class=\"extendedwopts-md-justify \">It is crucial to understand how moisture affects PA66 to ensure its correct use and storage. PA66 is a hygroscopic polymer, which means it has the ability to absorb water contained in the moisture of the environment. When PA66 goes through the lacquering process, it can lose the water it has absorbed, which results in a volumetric decrease (lower hammer tightness) and therefore a loss of values in the shear test. This can also result in surface finish defects after lacquering, also known as <em>blistering<\/em>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How do we manage this at STAC? PA66 Moisture Management Solutions<\/strong><\/h2>\n\n\n\n<p class=\"extendedwopts-md-justify \">At STAC, we are committed to offering innovative solutions that optimise the performance and efficiency of our profiles, while maintaining the highest quality at every stage of the process.<\/p>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li><strong><a href=\"https:\/\/www.stac.es\/en\/news\/procoat-solution\/\"><span style=\"text-decoration: underline;\">PROCOAT<\/span><\/a>: <\/strong>does not require special handling conditions beyond those used for standard material, which simplifies your application process. It also eliminates pre-treatment costs, ensuring a totally uniform and consistent finish. Thanks to its ability to increase the electrical conductivity of completely dry polyamide profiles, the powder coating adheres more easily and uniformly across the entire surface. This ensures optimal results, even on textured finishes and non-visible areas.<\/li>\n<\/ul>\n\n\n\n<ul class=\"extendedwopts-md-justify wp-block-list\">\n<li><strong>Thermoadhesive strip: <\/strong>Most profiles in the STAC catalogue have a thermoadhesive strip that melts during the lacquering process. This bead is inserted into the dovetail housings after the extrusion of the profiles and its main function is to fix the polyamide profile to the aluminium in order to improve the shear test values.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>STAC products made with PA66-GF25 ensure outstanding performance in terms of thermal insulation, contributing to
