heavily on experience, not just equipment<\/li>\n<\/ul>\n<p><strong>What buyers often underestimate:<\/strong><br \/>\nIf your downstream partner is set up for melt-processing, switching to PTFE usually means <strong>new tooling, longer lead times, and higher rejection risk<\/strong>.<\/p>\n<h3 class=\"wp-block-heading\">Mechanical Creep Is a Design Risk, Not a Footnote<\/h3>\n<p>PTFE is chemically stable but mechanically soft.<\/p>\n<ul class=\"wp-block-list\">\n<li>Deforms slowly under constant load<\/li>\n<li>Loses dimensional accuracy in long-term service<\/li>\n<li>Reinforcement fillers are often required<\/li>\n<\/ul>\n<p>In sealing or bearing applications, creep can lead to <strong>loss of tolerance, leakage, or premature replacement<\/strong>, even when chemical resistance is excellent.<\/p>\n<h3 class=\"wp-block-heading\">Batch Consistency Matters More Than the Datasheet<\/h3>\n<p>On paper, two PTFE batches may look identical.<br \/>\nIn practice, small variations can cause major downstream issues.<\/p>\n<ul class=\"wp-block-list\">\n<li>Sintering behavior may vary<\/li>\n<li>Machining results can drift<\/li>\n<li>Surface finish consistency may
