Rapid expression of the technology began as PTFE proved
critical to space travel. While not the exclusive focus, space
applications grew to include:
•
Use in early rockets through Mercury, Apollo and Space
Shuttle programs, communication satellites and “star
wars” defense systems.5
•
Rocket fuel tanks utilized PTFE in linings and to support
fuel lines.6
•
NASA used PTFE electric insulation in space ships from
the first Mercury programs.7
• The Apollo astronauts’ space suits contained layers of
PTFE fabric.8
• In the Space Shuttle, the liquid oxygen tank’s precious
cargo was protected with PTFE insulation.10
• PTFE was used in fabrication of the Space Shuttle’s
critical Thermal Protection System.11
• PTFE proved effective as cage material in the Space
Shuttle’s main engine’s high pressure oxygen pump bearings.

• PTFE composites reduced friction
and wear when utilized as dry lubricants in
aerospace bearing applications.13
• In the “star wars” Strategic Defense
Initiative, PTFE was used in light, quic
