Abstract

Polytetrafluoroethylene is rendered suitable for moulding at a temperature of 200 DEG C. or less by subjecting it to irradiation with ionizing radiations in amount equivalent to from 2 to 13 units of 50X106 roentgen. Irradiation may be by high energy neutrons, gamma rays, X-rays, high energy protons, electrons or helium ions or thermal neutrons. Specification 732,047 is referred to.ALSO:Polytetrafluorethylene is rendered suitable for moulding at a temperature of 200 DEG C. or less by subjecting it to irradiation with ionizing radiations in amount equivalent to from 2 to 13 units of 50 X 106 roentgen.
