The main raw material of PTFE sample capillary is polytetrafluoroethylene (PTFE), so it has excellent high temperature resistance, corrosion resistance, low friction coefficient and other characteristics. PTFE (polytetrafluoroethylene) is a high molecular polymer known for its extraordinary chemical stability. It is resistant to almost all strong acids, alkalis and strong oxidants, and does not react with organic solvents. The PTFE sample capillary is made by mixing PTFE dispersion resin with an organic solvent, pressing it at room temperature, and then going through a drying and sintering process.

    Features:

    1. High temperature resistance: This product has a very wide operating temperature range, from -80°C to 260°C. Even if it is used at high temperatures for a long time, its physical properties are almost unaffected.

    2. Corrosion resistance: This product can be used in harsh environments such as strong acid, strong alkali, and organic solvents.

    3. Low friction coefficient: PTFE has an extremely low friction coefficient. The friction coefficient of this product is usually only 0.04, which makes it an excellent self-lubricating material.

    4. Not easy to adhere: Because the surface electrical properties of PTFE are stable and it is not easy to form an electrostatic field, it is not easy to absorb pollutants such as tiny particles or organic substances. The inner wall of the PTFE sample capillary is not easy to adhere to colloids and chemicals.

    5. Electrical insulation: As a highly non-polar material, PTFE has good electrical insulation properties. Its dielectric constant is about 2.0, which is the smallest among all electrical insulating materials. The PTFE sample capillary also inherits this. characteristic.

    6. Aging resistance: This product has excellent aging resistance and can be used outdoors for a long time.
