Key words: subcritical freons, sterilization, «press-depress» regime, ultra high density polyethylene

For the first time the ability of ultra high density polyethylene (UHDPE) sterilization
with subcritical freons R22 and R410a without any modificators is demonstrated. The
maximum sterilization effect is achieved when freon R410a is used in a static regime at
50 °C and 250 bar during 30 min and with freon R22 during 60 min at 70 °C at a cyclic
pressure variation between 100 and 290 bar («press-depress» mode).
