Abstract: the high-temperature compression creep behavior of polytetrafluoroethylene(PTFE)was characterized using a home-made tester . the PTFE samples 6 mm x 6 mm x 50 .8 mm in size were tested at 250 C with a load of 5. 226 kg. the results showed that the stress of pure PTFE sample was 1.452 MPa, the creep quantity was 0. 56 mm, and the strain was 0. 011.the creep curve of the sample agreed with standard one.

Key words: polytetrafluoroethylene, compression creep, high-temperature creep tester
