PTFE flange

PEEK, PTFE Plastic Flange

A flange is a device used in the process of connection, sealing, and support of mechanical parts. It is a kind of important and indispensable part of engineering machinery production. The material of the general connection parts is carbon steel and stainless steel.

But nowadays, the plastic flange is widely used in municipal engineering, chemical industry, petroleum, and other industries. Plastic has many unique properties, such as chemical resistance, lightweight, and other benefits. Among the engineering plastic, the PEEK and PTFE are the most used ones.

We have large-sized PEEK rod that can machine different size plastic flanges.

Advantages of PEEK plastic flanges:

(1) It has good thermal resistance, and its heat resistance can reach 280 DEG C, so it is suitable for high-temperature occasions;

(2) There is no metallic impurity in the material, so there will be no leakage current during use;

(3) Strong chemical corrosion resistance, not afraid of corrosion by chemicals;

(4) The strength is relatively large, especially under the same stress conditions, the strength of PEEK plastic flanges is far superior to other materials;

(5) The weight is light and easy to install. If it is used in the same environment as stainless steel or copper, it can save more than 70% of the weight compared with stainless steel and more than 50% of copper;

(6) Good machinability, easy processing, and forming.

PTFE flange

Using PTFE to produce plastic flange is mainly because the PTFE material has a very low friction coefficient, high abrasion resistance, lightweight, high-temperature resistance, and chemical resistance. These properties make it a better plastic flange than others. In Keward, we can offer you both compressed and extrusion PTFE sheet.

The reason why PTFE is used to produce plastic flange can be summarized as follows:

  1. PTFE has excellent corrosion resistance.

2. PTFE has good chemical stability, resistant to all chemicals except molten alkali metals, fluorine, and fluorine-containing compounds.

3. PTFE has excellent electrical insulation properties. The dielectric constant is extremely stable over a wide frequency range at room temperature, and the dielectric loss angle tangent is extremely small in the entire frequency range. 4. PTFE is thermally stable and can be used under a vacuum at temperatures up to 250 °C. It can also be used as a sealing material in high-temperature environments above 260 °C for a short time.
