Teflon® PTFE 62XT X
DuPont ™ Teflon® PTFE 62XT X is a polytetrafluoroethylene fine powder resin used primarily for paste extrusion. Teflon ® PTFE 62XT X offers the excellent combination of properties typical of the Teflon® fluoropolymer resins:
- non-aging characteristics;
- chemical inertness to nearly all industrial chemicals and solvents;
- exceptional dielectric properties, stable with frequency and temperature;
- toughness and flexibility;
- low coefficient of friction;
- non-stick characteristics;
- negligible moisture absorption;
- excellent weather resistance;
- service temperature up to 260 °C (500°F);
- useful properties at -240°C (-400°F);
- moderate stiffness and high ultimate elongation.
Compared with other grades of PTFE fine powder, Teflon ® PTFE 62XT X is a premium resin that has increased thermal stability, superior flex life, superior stress crack resistance, low permeability and high clarity.
Teflon ® PTFE 62XT X is designed for processing at medium to high reduction ratios of 400:1 to 1600:1. It is particularly suitable for production of high quality tubing, spaghetti tubing and wire coating. This grade is also highly suitable for after-processing technologies such as flanging, welding, blow moulding and convoluting.
Teflon ® PTFE 62XT X meets the following requirements:
- ASTM D4895-10, Type I, Grade 3, Class D
Typical Applications
Teflon ® PTFE 62XT X is used primarily in the production of tubing installed in applications requiring the ultimate in reliability and performance. Applications are found in the chemical, pharmaceutical, and automotive industries where contact with hydraulic fluid, hydrocarbon fuel or reactive gases is required. One such application is high pressure tubing in heat exchangers.
