PTFE Bellows

PTFE Bellows

The full name for PTFE is Polytetrafluoroethylene, a synthetic polymer containing fluorotetrafluoroethylene. Non-colorant polytetrafluoroethylene is white to transparent. PTFE was discovered by DuPont in 1938 and Teflon is their registered brand. PTFE and Teflon are the same thing, just different names, and sometimes it’s also referred to as F4. Known as the king of plastics, PTFE not only resists high temperatures, but is insoluble in almost all solvents. Its best-known feature is non-stick, and PTFE-coated non-stick pans have appeared in many homes.

product details

The operating temperature of the PTFE corrugated pipe is from -30 degrees to 230 degrees, and the actual temperature range may vary slightly depending on the structure of the bellows assembly. For example, the operating temperature of a PTFE lined rubber expansion joint is determined by the type of rubber material used, with a maximum of about 100 degrees. Kipflex offers a comprehensive and diverse selection of PTFE bellows. They include not only PTFE bellows, PTFE expansion joint, but also a variety of flexible connectors lined with PTFE . They are PTFE lined bellows, PTFE lined expansion joint, PTFE lined rubber expansion joint, PTFE hose, PTFE lined hose. The combination of PTFE lining and convolution by high temperature molding greatly improves the pressure resistance of PTFE bellows and expands the application range.
