High-Temperature-Resistant PTFE Rod with Low Friction Coefficient--Processing Blank Rods

Product Description

I. Core Properties of PTFE Rods

• Excellent Corrosion Resistance
  It is resistant to corrosion by almost all chemical substances (including strong acids, strong alkalis, organic solvents, strong oxidants, etc.), and only has slight reactions with molten alkali metals,  Hence, it is known as the "King of Plastics".
• Superior High and Low Temperature Stability
  It has an extremely wide operating temperature range, capable of long-term use at -200ºC~260ºC. It does not melt or decompose at high temperatures, nor does it become brittle at low temperatures, maintaining stable physical properties.
• Extremely Low Coefficient of Friction
  Its friction coefficient is the lowest among plastics (static friction coefficient is approximately 0.04), and it has self-lubricating properties. It is not easy to adhere to other substances, making it suitable for scenarios requiring reduced friction and wear.
• Non-stick Property
  It has extremely low surface tension, so almost all substances are difficult to adhere to its surface. It is easy to clean and not prone to scaling.
• Excellent Electrical Insulation Performance
  It has high insulation resistance and corona resistance, unaffected by temperature and frequency, making it an ideal high-frequency insulation material.
• Strong Aging and Weather Resistance
  When exposed to the atmosphere for a long time (including ultraviolet rays, ozone, etc.), its performance remains almost unchanged, ensuring a long service life.

II. Main Application Scopes of PTFE Rods

• Chemical Industry
  • Manufacturing seals for pipelines, valves, and pumps (such as gaskets, sealing rings) to prevent leakage of chemical media.
  • Processed into linings or stirring rods for reactors and storage tanks to resist corrosion from strong acids and alkalis.
  • Used as support components for filter materials in filtration systems for corrosive liquids.
• Mechanical Manufacturing Industry
  • Producing wear-resistant parts such as bearings, bushings, and sliders, utilizing its low friction coefficient to reduce mechanical wear, especially suitable for oil-free lubrication occasions (e.g., food machinery, textile machinery).
  • Used as friction strips for guide rails to reduce noise and resistance during equipment operation.
• Electronics and Electrical Industry
  • Processed into insulating gaskets, insulating sleeves, binding posts, etc., for insulation protection of high-frequency cables, transformers, capacitors, and other equipment.
  • Used as insulating support components for electronic components in high-temperature or humid environments.
• Aerospace  Fields
  • Used as seals or pipeline components in the fuel systems of spacecraft and rockets, withstanding extreme high and low temperatures and fuel corrosion.
  • Applied as insulating and wear-resistant parts  equipment to adapt to harsh environments (e.g., high temperature, radiation, chemical corrosion).
• Other Fields
  • Manufacturing handles or accessories for non-stick pans and baking trays (need to be combined with metals after processing).
  • Used as thread guides in the textile industry to reduce frictional damage to threads.
