Process for producing moldings of ultra high molecular weight polyethylene
Реферат: In order to produce mouldings from ultrahigh-molecular-weight polyethylene, the polymer is heated to from 160 to 280@C in a mould without pressure or under a pressure of up to 0.5 MPa and then cooled to room temperature under a pressure of from 4 to 20 MPa.
