<li style="box-sizing: border-box; margin: 0px 0px 10px; padding: 0px; list-style: disc; outline: none; line-height: 28px;">Due to the nature of PTFE, the interface compatibility between the filler and the PTFE matrix should be considered when selecting the filler. It is necessary to pay attention to the difference in molecular polarity, the difference in surface tension, and the difference in internal stress caused by different expansion coefficients. The method can treat the surface of the filler or treat the surface of PTFE to increase their compatibility.</li>

Not choosing the best material.</li>
