Fabrication Guidelines for Mechanical PTFE<\/h3>\n

Cost vs. Performance:<\/strong>
\nMechanical PTFE is made from reprocessed resin. \u0646\u0635\u064a\u062d\u0629:<\/strong> While it retains the friction and chemical properties of Teflon, it has lower tensile strength. Use it for spacers and supports rather than high-pressure seals.<\/p>\n

Visual Identification:<\/strong>
\nReprocessed PTFE often has a slightly off-white or greyish tint compared to the bright white of Virgin PTFE. \u0646\u0635\u064a\u062d\u0629:<\/strong> Do not use this grade for high-purity medical or food applications where contaminants could be an issue.<\/p>\n

\u0642\u0627\u0628\u0644\u064a\u0629 \u0627\u0644\u062a\u0634\u063a\u064a\u0644:<\/strong>
\nIt machines very similarly to virgin PTFE but can be slightly more abrasive due to potential inclusions. \u0646\u0635\u064a\u062d\u0629:<\/strong> We use sharp carbide tools to ensure a smooth finish and prevent material “tearing.”<\/p>\n

Dimensional Creep:<\/strong>
\nReprocessed PTFE is prone to “cold flow” just like virgin material. \u0646\u0635\u064a\u062d\u0629:<\/strong> We design parts with adequate cross-sections and recommend using this grade for static applications rather than high-load moving parts.<\/p>\n<\/div>\n

Industrial Piping & Valves<\/strong>
\nCorrosion-resistant spacers, gaskets, and flange liners used in general chemical transport systems.<\/p>\n

Heavy Machinery<\/strong>
\nWear strips, slide plates, and support blocks where a low-friction surface is needed to protect moving metal parts.<\/p>\n

Electrical Enclosures<\/strong>
\nNon-critical insulating blocks and spacers that benefit from PTFE’s high arc resistance and thermal stability.<\/p>\n

Automotive Aftermarket<\/strong>
\nBushings and washers for non-critical assemblies where the chemical resistance of Teflon is desired at a budget-friendly cost.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
