It is commonly used as a protective coating material for surfaces. Notably, polyurethane offers significantly better wear resistance than many types of rubber and even some metals.<\/p>\n<p>In addition, polyurethane is resistant to oil, grease, fats, and organic solvents. It also has superior pressure resistance compared to conventional rubber, making it an ideal material for manufacturing heavy-duty wheels, couplings, and shock-absorbing components.<\/p>\n<p>Polyurethane does not tear easily during use, with tear strength ranging from approximately 500\u2013100 lbs\/inch\u2014much higher than most rubber materials. It also withstands environmental factors such as oxidation, sunlight, ozone, and harsh weather conditions. With excellent electrical insulation, elasticity, and impact resistance, polyurethane is widely used for cable insulation as well.<\/p>\n<p>Thanks to these properties, polyurethane is extensively applied in industrial applications such as heavy-duty wheels, couplings, protective coatings, and especially automatic door components.<\/p>\n<\/div>\n<figure id=\"attachment_19799\" aria-describedby=\"caption-attachment-19799\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-19799 size-full\" title=\"C\u1ea5u tr\u00fac ph\u00e2n t\u1eed polyurethane v\u1edbi \u0111o\u1ea1n c\u1ee9ng v\u00e0 m\u1ec1m\" src=\"https:\/\/sonha.com\/wp-content\/uploads\/2019\/10\/Polyurethane-la-gi-2.jpg\" alt=\"C\u1ea5u tr\u00fac ph\u00e2n t\u1eed polyurethane v\u1edbi \u0111o\u1ea1n c\u1ee9ng v\u00e0 m\u1ec1m\" width=\"1200\" height=\"674\" srcset=\"https:\/\/sonha.com\/wp-content\/uploads\/2019\/10\/Polyurethane-la-gi-2.jpg 1200w, https:\/\/sonha.com\/wp-content\/uploads\/2019\/10\/Polyurethane-la-gi-2-300x169.jpg 300w, https:\/\/sonha.com\/wp-content\/uploads\/2019\/10\/Polyurethane-la-gi-2-1024x575.jpg 1024w, https:\/\/sonha.com\/wp-content\/uploads\/2019\/10\/Polyurethane-la-gi-2-768x431.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption id=\"caption-attachment-19799\" class=\"wp-caption-text\"><em>Polyurethane molecular structure with hard and soft segments<\/em><\/figcaption><\/figure>\n<div id=\"Ctp_page_Bao_ChiTiet\" class=\"content_box\">\n<h3><span class=\"ez-toc-section\" id=\"Application_of_polyurethane_in_automatic_door_rollers\"><\/span>Application of polyurethane in automatic door rollers<em><br \/>\n<\/em><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In sliding door systems, the roller is the component that directly bears the load and determines smoothness, stability, and overall system lifespan.
