also called sodalimesilica glass, float glass or simply standard glass &#8211; is the dominant form of glass in use today; estimated to constitute 90% of all glass ever manufactured. As such, it forms the backbone of the modern glass industry.<\/p>\n          <p>Soda lime glass is In essence,&#8221; a network of silica (SiO) with the network formers, soda (NaO) and lime (CaO). Soda conducts as a flux &#8211; reducing the melting temperature from over 2,000 to around 1,100. Lime conducts as a stabiliser &#8211; improving chemical durability to make the glass water insoluble.<\/p>\n          <p>Arguably the most workable glass material available, soda lime is easy to redeform and remelt, and handles reprocessing in-furnace with ease. Recyclable without degradation and with abundance of raw materials, it is the most low cost form of glass.<\/p>\n        <\/div>\n      <\/div>\n\n      <h3 class=\"slg-wim-h3\">Common Uses of Soda Lime Glass<\/h3>\n      \n      <ul class=\"slg-wim-uses\">\n        <li class=\"slg-wim-card\">\n          <strong>Window panes and architectural glass<\/strong> \n          <span>the (float) flat glass industry.<\/span>\n        <\/li>\n        <li class=\"slg-wim-card\">\n          <strong>Bottles and jars<\/strong> \n          <span>packaging for food, drink and pharmaceutical use.<\/span>\n        <\/li>\n        <li class=\"slg-wim-card\">\n          <strong>Tableware, bakeware and oven dishes<\/strong> \n          <span>drinking glasses, plates and cookware.<\/span>\n        <\/li>\n        <li class=\"slg-wim-card\">\n          <strong>Industrial cover glass<\/strong> \n          <span>data panels, touch panels and control panel covers.<\/span>\n        <\/li>\n        <li class=\"slg-wim-card\">\n          <strong>Car glass<\/strong> \n          <span>screens (laminated glass) and side windows (tempered).<\/span>\n        <\/li>\n      <\/ul>\n\n      <div class=\"slg-wim-conclusion\">\n        <p>We purchase and process soda lime every day at SW GLASS and regularly mark its impressive optical and mechanical qualities, temper ability, and cost effectiveness as a core advantage of our industrial cover glass applications.<\/p>\n      <\/div>\n\n    <\/div>\n  <\/div>\n<\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-4390af5\" data-block-id=\"4390af5\"><style>.stk-4390af5 {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-4390af5-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-eb8dc42\" data-v=\"4\" data-block-id=\"eb8dc42\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-eb8dc42-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-eb8dc42-inner-blocks\">\n<style>\n  \/* * \u6a21\u5757\u7ea7\u6700\u9ad8\u9694\u79bb\uff1a\u6240\u6709\u7684\u6837\u5f0f\u5168\u90e8\u901a\u8fc7\u7279\u5b9a ID \u524d\u7f00\u4e0e Class \u7ed3\u5408\u63a7\u5236\u3002\n   * \u9075\u5faa\u6781\u7b80 B2B \u6241\u5e73\u5316\u98ce\u683c\uff0c\u65e0\u9634\u5f71\uff0c\u65e0\u5197\u4f59\u8fb9\u6846\u3002\n   *\/\n\n  \/* \u5916\u90e8\u5168\u5bbd\u5bb9\u5668\uff0c\u5185\u90e8\u9650\u5236 1280px \u5e76\u5c45\u4e2d *\/\n  #soda-lime-glass-unique-module .slg-mod-container {\n    width: 100%;\n    background-color: #ffffff;\n    padding: 40px 0;\n    box-sizing: border-box;\n    \/* \u4e0d\u8bbe\u7f6e font-family\uff0c\u5b8c\u7f8e\u7ee7\u627f Blocksy \u5168\u5c40\u5b57\u4f53 *\/\n  }\n\n  #soda-lime-glass-unique-module .slg-mod-wrapper {\n    max-width: 1280px;\n    margin: 0 auto;\n    padding: 0 20px;\n    box-sizing: border-box;\n    color: #333333;\n    line-height: 1.6;\n  }\n\n  \/* \u6807\u9898\u7cfb\u7edf\u5c42\u7ea7\u63a7\u5236 *\/\n  #soda-lime-glass-unique-module .slg-mod-h2 {\n    font-size: 32px;\n    text-align: center;\n    color: #304890 !important;\n    margin: 0 0 32px 0 !important;\n    font-weight: 700;\n  }\n\n  #soda-lime-glass-unique-module .slg-mod-desc-top {\n    text-align: center;\n    max-width: 1000px;\n    margin: 0 auto 40px auto;\n    color: #555555;\n    font-size: 1.05rem;\n  }\n\n  \/* \u9ad8\u7ea7\u6781\u7b80\u8868\u683c\u8bbe\u8ba1\uff1a\u53bb\u8272\u5757\uff0c\u7559\u7ebf\u6761 *\/\n  #soda-lime-glass-unique-module .slg-mod-table-wrap {\n    width: 100%;\n    overflow-x: auto;\n    margin-bottom: 36px;\n  }\n\n  #soda-lime-glass-unique-module .slg-mod-table {\n    width: 100%;\n    border-collapse: collapse;\n    min-width: 800px;

An additional advantage is that soda lime can be effectively tempered using both physical and chemical processes, with the obvious advantages in protection and mechanical strength. With no modifications, tempered soda lime glass achieves mechanical strength of 120-200 MPa. No destructive shards are formed in the break, tempered soda lime glass will break into small, relatively harmless pieces.<\/div>\n      <\/article>\n\n      <article class=\"sw-choice-card\">\n        <h3 class=\"sw-h3-title\">When to Choose Borosilicate Glass<\/h3>\n        <div class=\"sw-card-text\">The major advantage that borosilicate has over soda lime is in its excellent chemical and thermal shock resistance. Its coefficient of thermal expansion is only 3.3 10\/ C making it resistant to sudden contact with differing Temperatures in the concentration range of 300-500 C. Borosilicate does not leach chemicals even in extreme pH environments and is thus the conventional choice in applications utilizing aggressive chemicals, be it table ware, laboratory ware or pharmaceutical packaging. It is the addition of the B2O3 constituent that affords borosilicate the excellent chemical and thermal shock properties.<\/div>\n      <\/article>\n\n    <\/div>\n\n    <aside class=\"sw-perspective-box\">\n      <h3 class=\"sw-perspective-title\">SW GLASS Perspective<\/h3>\n      <div class=\"sw-perspective-text\">SW GLASS can process both soda lime glass and borosilicate glass for use in both custom chemical environments and general flat glass applications, but we tend to specify very high levels of custom soda lime float glass processing for almost all display or cover glass projects due to its vastly superior cost to performance benefits. We would point out to prospective project managers that more than 95% of touch panel, HMI display and appliance cover glass applications are best suited to chemical strengthening or tempering of soda lime glass. Savings can be considerable, and the results are better.<\/div>\n    <\/aside>\n\n  <\/div>\n\n  <script>\n    (function() {\n      const comparisonModule = document.getElementById('sw-glass-comparison');\n      if (comparisonModule) {\n        \/\/ Scripts isolated.

We can temper soda lime glass for application at a mechanical strength ranging from 120-200 MPa or more, far more than can be economically obtained with borosilicate glass. None of the dots will shatter into dangerous shards, soda lime glass when chemically hardened, comes apart into thousands of glass fragments of manageable size.<\/p>\n        \n        <p class=\"sw-paragraph\">Thermal shock and chemical resistance are where borosilicate glass really outperforms soda lime. Its coefficient of expansion is a low 3.3 \u00d7 10\u207b\u2076\/\u00b0C allowing it to withstand heat differential approaches of around 300\u00b0C without shattering. It also contains no leachable chemicals and maintains its inert properties even at extremely high or low pH levels. This is why borosilicate is considered the &#8216;working man&#8217; of the glass industry, designated for use in chemical production, handling and pharmaceutical\/ laboratory equipment, and even art ware.<\/p>\n\n        <p class=\"sw-paragraph\">We process both Borosilicate and soda lime, but for industrial display and cover glass applications, we have vast experience in the use of chemically strengthened soda lime glass. Our experience dictates that 95% of touch panel, HMI display and appliance cover glass projects are appropriately served by chemical strengthening or tempering of soda lime glass. The cost is considerably lower, and the end result appears to be more robust.<\/p>\n      <\/div>\n    <\/header>\n\n    \n\n    <div class=\"sw-apps-grid\">\n      \n      <article class=\"sw-app-card\">\n        <div class=\"sw-app-num\">01<\/div>\n        <div class=\"sw-app-content\">\n          <h3 class=\"sw-h3-title\">Touch Display &#038; Control Panels<\/h3>\n          <p class=\"sw-card-desc\">Industrial HMI panel displays, marine navigation screens, crane operator display covers, and self-service kiosk screens.

Physical tempering requires a minimum thickness of 3 mm &#8211; that is a fundamental limitation of the thermal quenching process. We process tens of millions of 1.1 mm and 2.0 mm thick soda lime glasses using chemical strengthening, routinely achieving residual compressive stress levels above 450 MPa with a depth of layer over 8 microns. These parameters are confirmed on each batch of glass produced using surface stress measuring equipment.<\/p>\n      <\/aside>\n\n      <div class=\"sw-conclusion-area\">\n        <h3 class=\"sw-h3-conclusion\">Choosing the Right Strengthening Method<\/h3>\n        <p class=\"sw-conclusion-text\">The most common decision between physical tempering and chemical strengthening is glass thickness. For glasses 3 mm thick and greater, physical tempering is more cost effective and provides sufficient strength. For negatives lower than 3 mm, chemical strengthening is the only process option. We selectively to treat glasses such as thicker substrates by physical tempering and then to chemically strengthen them in specialist applications requiring the highest possible performance. Both methods form residual surface compressive stress that significantly enhances impact resistance, surface durability and flexural strength.<\/p>\n      <\/div>\n\n    <\/div>\n\n  <\/div>\n\n  <script>\n    (function() {\n      const sodalimeStrengtheningModule = document.getElementById('sw-sodalime-strengthening');\n      if (sodalimeStrengtheningModule) {\n        \/\/ Javascript scope is completely isolated.\n        \/\/ Pure CSS Grid logic avoids any reflow or CLS issues, ensuring maximum compatibility with FlyingPress lazy-loading.\n      }\n    })();\n  <\/script>\n<\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-653da32\" data-block-id=\"653da32\"><style>.stk-653da32 {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-653da32-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-5f2a92f\" data-v=\"4\" data-block-id=\"5f2a92f\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-5f2a92f-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-5f2a92f-inner-blocks\">\n<section id=\"sw-processing-matrix\">\n  <style>\n    \/* =========================================\n       1.

Chemical resistance is also moderate, making it attacked by strong alkalis and hydrofluoric acid. Relative to borosilicate glass (heat resistant to ~160C thermal shock), COE is higher (8.5-9.5\u00d710\u207b\u2076\/\u00b0C over 3.3\u00d710\u207b\u2076\/\u00b0C).

Physical constant involves heating soda lime to 620-680 C and duct rapid air cooling, resulting in glass 45% stronger than annealed glass at a safety margin of 250 Mpa. Chemical tempering involves placing glass into a potassium salt bath, exchanging the larger K ions with smaller Na ions, producing compressive internal stress greater than 450 MPa all over the glass &#8211; this method can be used on glass less than 3mm thick, but borosilicate is very difficult to temper at all.<\/p>\n          <\/div>\n        <\/div>\n      <\/article>\n\n      <article class=\"sw-accordion-item\">\n        <h3 class=\"sw-h3-title\">\n          <button class=\"sw-accordion-trigger\" aria-expanded=\"false\">\n            <span class=\"sw-question-text\">What temperature does soda lime glass melt at?<\/span>\n            <span class=\"sw-icon\" aria-hidden=\"true\"><\/span>\n          <\/button>\n        <\/h3>\n        <div class=\"sw-accordion-content\" aria-hidden=\"true\">\n          <div class=\"sw-answer-inner\">\n            <p class=\"sw-paragraph\">Soda lime glass begins to soften close to 700C, on its melting point of around 1,500-1,700C.
