Both are silicate glasses, but they solve different problems. Here is a chart of measured difference in properties, not marketing hype.<\/p>\n      \n      <h4>Thermal Cycling &#038; Applications<\/h4>\n      <p>A CTE difference of 3.3 vs 9.0 tells us borosilicate handles temperature swings around 4 better than soda lime. For applications like industrial sight glasses, oven viewing windows, or lighting covers which undergo thermal cycling every day, soda-lime glass will simply fail.<\/p>\n      \n      <h4>The Tempering Misconception<\/h4>\n      <p>Soda-lime glass can be tempered to boost impact strength by 4-5, but tempering does nothing to increase its thermal shock resistance. If your application is exposed to heat, borosilicate wins.<\/p>\n    <\/div>\n\n    <div class=\"db-table-area\">\n      <div class=\"db-table-wrapper\">\n        <table>\n          <thead>\n            <tr>\n              <th>Property<\/th>\n              <th>Borosilicate<\/th>\n              <th>Soda-Lime<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>CTE (\u00d710\u207b\u2076\/K)<\/td><td>3.3<\/td><td>9.0<\/td><\/tr>\n            <tr><td>Thermal Shock<\/td><td>~160\u00b0C<\/td><td>~37\u00b0C<\/td><\/tr>\n            <tr><td>Max Temp<\/td><td>500\u00b0C<\/td><td>250\u00b0C<\/td><\/tr>\n            <tr><td>Resistance<\/td><td>Class 1<\/td><td>Class 3<\/td><\/tr>\n            <tr><td>Density (g\/cm\u00b3)<\/td><td>2.23<\/td><td>2.50<\/td><\/tr>\n            <tr><td>Relative Cost<\/td><td>3\u20135\u00d7<\/td><td>Baseline<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n      \n      <div class=\"db-btn-wrapper\">\n        <a href=\"#ct-popup-787\" class=\"db-btn\">Get Instant Quote<\/a>\n      <\/div>\n    <\/div>\n\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-b62a697\" data-block-id=\"b62a697\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-b62a697-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-f74299a\" data-v=\"4\" data-block-id=\"f74299a\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-f74299a-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-f74299a-inner-blocks\">\n<style>\n  \/* * Scope: #borosilicate-applications-module \n   * Framework: Vanilla CSS (Grid 2x2)\n   * Fonts: Inherits from Blocksy global settings\n   *\/\n\n  #borosilicate-applications-module {\n    width: 100% !important;\n    padding: 40px 0 !important;

Chemical strengthening increase drop test pass from 60% (annealed) to 97%.<\/p>\n          <p class=\"bcs-text bcs-highlight-result\">Result: Zero field returns for thermal cracking over 12 months.

The current cover glass was showing surface hazing after three months with the cleaning cycle.<\/p>\n          <p class=\"bcs-text\">We finished 2.5 mm boroniatorulte panels with AG (anti- glare) etching and AF (anti-fingerprint) coating. Chemical resistance was strong enough to preclude the surface hazing that had ruined soda-lime covers in the past. 4-month post-installation wipe cycle simulations with hospital grade disinfectant without detectable change in the glare or touch sensitivity.<\/p>\n          <p class=\"bcs-text bcs-highlight-result\">Result: Surface haze reduced from 3.2% to below 0.5% after 6 months of clinical use.
