Ultrahigh-molecular-weight polyethylene film was continuously manufactured from reactor powder by calendar rolling under controlled processing conditions. Subsequent tensile drawing above the melting temperature gave a maximum draw ratio of 10 at 150 C. The resultant tensile modulus and strength reached maximum values of 80 and 0.8 GPa, respectively. A loop strength of 0.4 GPa was achieved, which is much higher than that obtained by previous reactor-powder drawing below the melting temperature. A combination of rolling compression and tensile drawing in the molten state produces these superior mechanical properties.
