Product Description
Graphite Filled PTFE
The percentages used vary between 5 and 15%. Graphite lowers the coefficient of friction and is, therefore, often added to other types of filled PTFE for improving this property. It improves the deformation under load, strength and, to a minor degree, the wear properties.
Graphite filled PTFE has exceptional chemical resistance and is compatible with most hydraulic fluids. Outstanding performance when used for hydraulic/pneumatic compression type rod and piston seals, bearing bands and rotary application.
Features and Benefits
Advantages of Graphite-Filled PTFE:
- Low coefficient of friction compared to other filled PTFE materials.
- Higher flexural modulus and surface hardness than unmodified PTFE.
Disadvantages of Graphite-Filled PTFE:
- Lower notched impact strength, tensile strength, elongation at break and electrical characteristics compared with unmodified PTFE.
- Tendency of graphite to leach out.
Exceptional Durability and Corrosion ResistanceThe PTFE filled graphite material stands out for its outstanding corrosion resistance and mechanical strength. Designed to perform efficiently in aggressive chemical settings, these sheets resist degradation over time, providing extended service life and minimizing maintenance in demanding industrial applications.
Ideal Dimensions for Versatile ApplicationsWith a thickness between 10 and 20 millimeters and a width of 5 to 10 millimeters, these sheets are versatile enough for custom fabrication. Their dimensional range makes them suitable for a variety of sealing and insulation tasks where precision and sustained performance are essential.
FAQ's of PTFE Filled Graphite:
Q: How is PTFE filled graphite used in industrial applications?
A: PTFE filled graphite is primarily used in the form of gaskets and seals for pipelines, pumps, and valves in chemical plants, refineries, and other industries where exposure to corrosive media is common. Its unique composition ensures excellent chemical inertness and mechanical performance.
Q: What are the key benefits of using PTFE filled graphite?
A: The main benefits include high resistance to chemicals and corrosion, low friction, excellent sealing properties, and the ability to withstand a wide temperature range. These features combine to deliver reliable and long-lasting solutions in harsh environments.
Q: When should you consider PTFE filled graphite over pure PTFE or pure graphite?
A: You should opt for PTFE filled graphite when you require both the chemical resistance of PTFE and the enhanced strength and heat conductivity provided by graphite. This blend is especially beneficial in applications involving high pressure, temperature fluctuations, and aggressive chemicals.
Q: Where can I source PTFE filled graphite sheets in India?
A: PTFE filled graphite sheets with specified dimensions are available through trusted distributors, suppliers, and traders across India. Simply contact a reliable industrial material provider to inquire about availability and delivery options.
Q: What is the process for manufacturing PTFE filled graphite sheets?
A: The manufacturing process involves blending finely ground graphite with PTFE resin and then molding and sintering the mixture under heat and pressure. This process ensures uniform distribution of graphite, resulting in improved physical properties and durability.
Q: Can the dimensions be customized as per specific project requirements?
A: Yes, many distributors and suppliers in India offer customization services for PTFE filled graphite sheets, allowing you to specify thickness and width within the range of 10-20 mm and 5-10 mm, respectively, catering to your application's precise needs.
