Systems?<\/h2>\n<p>The material of a pneumatic seal directly impacts its <strong>durability<\/strong>, <strong>wear resistance<\/strong>, e <strong>compatibility<\/strong> with different environments.<\/p>\n<p>Incorrect material choices can result in:<\/p>\n<ul>\n<li><strong>Desgaste prematuro e vazamento<\/strong><\/li>\n<li><strong>Swelling or hardening<\/strong> devido \u00e0 exposi\u00e7\u00e3o qu\u00edmica<\/li>\n<li><strong>Reduced efficiency and costly downtime<\/strong><\/li>\n<\/ul>\n<p>That\u2019s why understanding when to use <strong>NBR<\/strong>, <strong>TPU<\/strong>, ou <strong>FKM<\/strong> is essential for achieving optimal system performance.<\/p>\n<h2>What Is NBR and Why Is It Used in Pneumatic Seals?<\/h2>\n<p>NBR is the most <strong>common material for pneumatic seals<\/strong>, valued for its <strong>affordability<\/strong>, <strong>flexibilidade<\/strong>, e <strong>oil resistance<\/strong>.<\/p>\n<h3>Key Advantages of NBR Seals:<\/h3>\n<ul>\n<li>Boa resist\u00eancia a \u00f3leos e graxas<\/li>\n<li>Acess\u00edvel e f\u00e1cil de fabricar<\/li>\n<li>Flex\u00edvel em baixas temperaturas (-30\u00b0C a
