However, there’s a catch. Glass is abrasive. If you use glass-filled PTFE on a soft shaft (like unhardened aluminum or mild steel), the seal won’t wear out, but the shaft will.<\/strong><\/p>\n\n\n\n I\u2019ve seen customers destroy a $500 shaft to save $2 on a seal. Don’t be that guy.<\/p>\n\n\n\n In automotive applications, temperatures fluctuate wildy. -40\u00b0C in winter to 150\u00b0C under the hood. Virgin PTFE has a high coefficient of thermal expansion and low creep resistance.<\/p>\n\n\n\n Deformation under load (14 MPa @ 23\u00b0C for 24 hrs):<\/strong><\/p>\n\n\n\n If you need the seal to maintain geometry under clamping force, you gotta go filled.<\/p>\n\n\n\n Heat kills seals. Virgin PTFE is a thermal insulator. It traps heat at the sealing interface. This leads to carbonization of the oil or melting of the seal lip.<\/p>\n\n\n\n Carbon filled PTFE<\/strong> is the hero here. It conducts heat away from the contact point.<\/p>\n\n\n\n If you have a high-speed rotary application (like a crank seal), moving that heat away is critical.<\/p>\n\n\n\n PTFE\u30c6\u30d5\u30ed\u30f3\u30ac\u30b9\u30b1\u30c3\u30c8\u306f\u3001\u6975\u9650\u6e29\u5ea6\uff08-200\u2103\uff5e+260\u2103\uff09\u306e\u8010\u71b1\u6027\u3068\u8010\u85ac\u54c1\u6027\u3092\u5099\u3048\u3001\u9ad8\u5727\u30dc\u30fc\u30eb\u30d0\u30eb\u30d6\u3084\u8150\u98df\u6027\u6d41\u4f53\u30b7\u30b9\u30c6\u30e0\u306e\u30b7\u30fc\u30eb\u306b\u6700\u9069\u3067\u3059\u3002\u3053\u308c\u3089\u306e\u30ac\u30b9\u30b1\u30c3\u30c8\u306f\u3001\u77f3\u6cb9\u30fb\u30ac\u30b9\u3001\u5316\u5b66\u30d7\u30ed\u30bb\u30b9\u3001\u7523\u696d\u6a5f\u68b0\u306b\u304a\u3044\u3066\u512a\u308c\u305f\u6f0f\u308c\u9632\u6b62\u6027\u80fd\u3092\u767a\u63ee\u3057\u307e\u3059\u3002\u5f62\u72b6\uff08\u30d5\u30e9\u30c3\u30c8\u3001\u30e9\u30a4\u30ca\u30fc\u3001\u30ea\u30f3\u30b0\uff09\u306f\u30ab\u30b9\u30bf\u30de\u30a4\u30ba\u53ef\u80fd\u3067\u3001\u8907\u96d1\u306a\u6a5f\u68b0\u69cb\u9020\u306b\u3082\u9069\u5fdc\u3057\u307e\u3059\u3002<\/p>\n\n\t\t\t<\/div><\/div>\n\n\n Okay, so you know you need filled.

Real World Scenario: The “Leaky” Transmission Case<\/h2>\n\n\n\n
During the 100-hour durability test, the shifting got sloppy. Eventually, the pressure dropped, and the transmission failed.<\/p>\n\n\n\n
We pulled the seals. They looked like pancakes. The heat generated by the rapid actuation, combined with the hydraulic pressure, caused the Virgin PTFE to cold flow. The seal lip flattened out, loss of contact pressure -> leak.<\/p>\n\n\n\n
We switched them to a custom 15% Glass + 5% MoS2 filled PTFE<\/strong>.<\/p>\n\n\n\n\n
