<p>PROBLEM TO BE SOLVED: To provide an ultrafine-molecular weight polyethylene rolled molding having high strength and heat resistance and excellent wear resistance.SOLUTION: An ultrahigh-molecular weight polyethylene-made rolled molding uses an ultrahigh-molecular weight polyethylene particle meeting conditions (1) an intrinsic viscosity ([η]) of 15-60 dl/g, (2) a bulk density of 130-700 kg/mand (3)ΔTm (ΔTm=Tm-Tm), or a difference between the melting point (Tm) of the first scan and the melting point (Tm) of the second scan measured with a differential scanning type calorimeter(DSC), of 11-30°C and has a draw ratio of twice or higher.</p> |
