FLUORORESIN IMPREGNATED CARBON MATERIAL

摘要

PURPOSE:To endow a carbon material with an excellent environmental insulating performance which is developed over a long period of time and establish a tecknolozy by which an excellent impermeability and thermal conductivity should be exhibited. CONSTITUTION:The pores in a carbon material having 5-20% open porosity and 0.3-2.5mum average pore radius are impregnated with fluororesin at >=40% rate of impregnation to obtain the objective fluororesin impregnated carbon material having <=0.3mum average pore radius.
