Product type
Polytetrafluoroethylene (PTFE) is a high-performance engineering plastic known for its exceptional chemical resistance, low friction properties, and high-temperature stability. It is a fluoropolymer that is produced through the polymerization of tetrafluoroethylene, resulting in a material that is non-reactive and has a very low coefficient of friction. PTFE is commonly used in applications where resistance to harsh chemicals and thermal stability are critical.
| Temperature range | -200°C to 260°C |
| Chemical resistance | Excellent against acids, bases, and solvents |
| Density | 1.5 to 2.2 g/cm³ |
| Tensile strength | 20 to 30 MPa |
| Dielectric strength | 20 kV/mm |
When selecting polytetrafluoroethylene, consider the specific application requirements such as temperature and chemical exposure. It is important to specify the desired thickness, form (sheets, rods, films), and any necessary certifications for food or pharmaceutical use. Additionally, quantities should be clearly defined to ensure proper pricing and availability.
