It exhibits a tensile strength of at least 15.0 MPa, with an elongation at break greater than or equal to 150%. The material has an exceptionally low water absorption rate of less than 0.01%. It also features an impressive dielectric strength of 10 kV\/mm, providing excellent electrical insulation. The contraction percentage is minimal, below 0.4%. With a wide working temperature range of -200\u00b0C to +260\u00b0C, the plate can tolerate short-term exposure to temperatures as high as 300\u00b0C without compromising its integrity.<\/p>\n<h2 data-start=\"2906\" data-end=\"2944\">Performance in Different Conditions<\/h2>\n<p data-start=\"2946\" data-end=\"3501\">This perforated PTFE round plate is designed for low to medium-pressure static sealing applications. Its mechanical properties, including flexibility and high chemical resistance, make it ideal for use in piping systems that experience thermal expansion and contraction, installation errors, or foundation settlement. The specific pressure range depends on the plate\u2019s thickness, hole design, and backing support strength, but it typically performs well in conditions under 1 MPa (10 Bar), which should be evaluated according to the application structure.<\/p>\n<h2 data-start=\"3503\" data-end=\"3516\">Conclusion<\/h2>\n<p data-start=\"3518\" data-end=\"3840\">The perforated PTFE round plate is a versatile and durable component for a wide range of industrial applications.
