The coefficient of linear thermal expansion of the porous matereals based on PTFE-4
Keywords:
porous PTFE-4, the coefficient of linear thermal expansion
Abstract
The influence of porosity of PTFE-4 on the coefficient of linear thermal expansion in the range from - 150 to +100 ºС was studied. In the range of 20 to 30ºС maximum is observed in the temperature dependence associated with the phase transition of the second type.
