PTFE rod 4-120 mm diameter selectable

PTFE rods are rods molded by molding, paste extrusion or plunger extrusion for processing various gaskets, seals and lubricating materials that work in corrosive media, as well as electrically insulating parts that are used at various frequencies, etc. Unfilled PTFE resins (recycled PTFE resins can be included) are used in this process.

PTFE rod is made of Polytetrafluoroethylene (PTFE), which has good corrosion resistance, abrasion resistance and high temperature performance. It has good corrosion resistance and can resist corrosion of various acid and alkali solutions, even extreme hot water and steam. It has excellent abrasion resistance and can effectively resist wear and tear at high temperatures, so it can be used in higher temperature environments. It also has excellent high-temperature performance, can withstand temperatures up to 260 ℃, and has good thermal stability and heat resistance.

The characteristics of PTFE rods

1, The use of a wide range of temperatures (Celsius from -200 degrees to +260 degrees).

2, Basically all chemicals have corrosion resistance in addition to some fluoride and alkaline metal fluids.

3, Excellent mechanical properties including aging resistance, especially for bending and swinging applications.

4, Outstanding flame retardancy (in line with ASTM-D635 and D470 test steps, in the air is regulated as flame retardant materials.

5, Excellent insulation properties (regardless of frequency and temperature)

6, Very low water absorption, and has a series of unique properties such as self-lubricating and non-stick.

Application areas of polytetrafluoroethylene rods

1. Electrical and electronic industry: PTFE rod has important application value in electrical and electronic industry. It has excellent electrical insulation properties and can be used as insulating material for electronic components, such as the insulation layer of wires and cables, and the isolation liner of electronic components. In addition, the low coefficient of friction of PTFE rods makes them ideal for dustproof and friction reduction in electronic equipment.

2. Liquid transmission field: Due to its strong corrosion resistance, PTFE rods are widely used in liquid transmission systems in chemical, petroleum and pharmaceutical industries. PTFE rods can not only resist the erosion of various acids, alkalis, organic solvents and other chemicals, but also maintain excellent performance at very low temperatures to ensure the safety and reliability of the transmission process.

3. Mechanical manufacturing field: PTFE rod's low coefficient of friction and excellent self-lubrication make it an important material in the field of mechanical manufacturing. It can be used as a material for transmission parts such as bearings, gears, piston rings, etc. to reduce friction and wear and prolong service life. In addition, PTFE rods can also be used to make seals to effectively prevent leakage and penetration.

4. Food processing industry: PTFE rod is a non-toxic, odorless material that meets food hygiene standards and is widely used in the food processing industry. It can make all kinds of high-temperature and corrosion-resistant containers, pipes and fittings for food storage, heating and transportation to ensure the quality and safety of food.

5. Other fields: PTFE rods are also widely used in aerospace, medical devices, automobile manufacturing, construction engineering and other fields. In the field of aerospace, PTFE rods are used as seals for aviation engines and high temperature resistant isolation plates. In the field of medical devices, PTFE rods can be used to make surgical instruments, artificial heart valves and so on. In the field of automobile manufacturing, PTFE rods are widely used as seals and dustproof parts of automobile engines. In the field of construction engineering, PTFE rods are commonly used for corrosion-resistant pipes and transparent partitions, etc.

Types of fillers for PTFE rods

Filled PTFE rods are made by adding a certain percentage of filler on the basis of pure PTFE rods. According to different application requirements, the following common fillers can be used: glass fiber, carbon fiber, copper powder, molybdenum disulfide and so on. These fillers can improve the mechanical strength, wear performance and thermal conductivity of PTFE rods, making them suitable for more demanding working conditions.

Q&A
