Material selection of pan plug seals in different working conditions

2022 07/02

1. Pure PTFE: good chemical properties, wide temperature resistance range, small friction coefficient, small starting friction, easy to wear and crawl, in line with FDA certification, used in light load, chemical, food, pharmaceutical industries, operating temperature -60+ 260℃

2. PTFE filled copper powder: good sliding and wear resistance, good crawling resistance, good compression resistance, good extrusion resistance; commonly used as ladder sealing ring, guide wear ring and other materials.

3. PTFE-filled carbon fiber: standard sealing material for mobile hydraulic systems and rotary motion occasions, especially suitable for water and water-soluble solutions, with good wear resistance under high temperature, high pressure and high speed, used in dry or low lubrication conditions It has a grinding effect on soft metals, and the operating temperature is -60+260℃

4. PTFE-filled polyester resin: It has good physical properties and has no hardness requirements on the working surface. It is widely used in soft metal materials such as stainless steel, aluminum and bronze on the working surface. The operating temperature is -60+260℃

5. Polyetheretherketone PEEK: radiation resistance, hydrolysis resistance, compression resistance, strong corrosion resistance, special wear resistance, very good friction performance, high modulus material, use temperature -60+260℃;

6. Ultra-high molecular weight polyethylene UHMW-PE: has good physical properties, especially wear-resistant, suitable for water-based media containing sediment and particles, very good low-temperature working performance, can be used for ultra-low temperature such as liquid nitrogen and liquid oxygen Environment, low requirements for the hardness of the working surface, the working surface is chrome-plated steel, stainless steel, aluminum, bronze, etc. in line with FDA certification, can be used in the food and pharmaceutical industry, the operating temperature -160+100 ℃

7. Nitrile rubber NBR: suitable for petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricating oil, gasoline, water, silicone grease, silicone oil and other media. It is currently widely used and has very low cost. rubber sealed loop

8. Polyurethane PU: Polyurethane rubber has very good mechanical properties, wear resistance and high pressure resistance are far superior to other rubbers, aging resistance, ozone resistance, oil resistance are also very good, but it is easy to hydrolyze at high temperature, and is generally used for high pressure resistance. , wear-resistant sealing link, one-time use temperature -45+110℃
