A comprehensive experimental study on the effect of temperature, static load and electron beam irradiation on thermomechanical properties of polytetrafluoroethylene material was conducted. Four regions having different nature were detected on the curves of dependences of deformation ( ) from temperature (t). The obtained curves of from t prove the presence of phase transitions in this film. Irradiation significantly affects the dependence of (t) and (σ).
