Surface Modification of the UHMW-PE Film Processing by Hot Compression Molding

Abstract

The properties of UHMW-PE film produced by hot compression molding and films modified by acid and anti-static agent were characterized. The results showed that: a) the thickness distributing of the film which processing by calendar rolling with conventional design roller is inhomogeneity; the tensile strength was 37.22 MPa, the elongation at break was 368.00%; the transmittance increases with wavelength redshift shows short-wave absorption and long-wave transmission; initial temperature of dissociation is 320°C; the surface resistance 1010 Ω and maximum is higher than 1016 Ω. b) Acid modification the surface of UHMW-PE film moderates the surface antistatic performance. C) After modified the film with external anti-static agent, the surface resistance was around 107Ω, but anti-static properties loss rapidly after friction. If modified the film with internal anti-static agent, the surface resistance was around 1010 Ω and have a long-lasting anti-static effect.

Particle morphology, structure and properties of nascent ultra-high molecular weight polyethylene

“…Ultra-high molecular weight polyethylene (UHMWPE), a typical polyolefin having a viscosityaverage molecular larger than 1 × 10 6 g mol −1 , is featured by excellent self-lubrication properties, high impact strength and high chemical stability, which is widely used in many applications including textile, chemical industry, packaging, artificial joints and other field [16][17][18][19]. However, the polymer chains of UHMWPE are prone to become entangled, forming a large number of physical entanglements.…”

Study on the Properties of UHMW-PE Film

“…Hot compression molding is a new method which is expected to use for the industrial production of high-strength UHMW-PE film. We had investigated the performance of UHMW-PE film prepared by small section production line using double-roller hot compression molding, then hot pressing mold method by the third roller was characterized, finally, modified the surface of the film [11]. Our aim is to gain the change of surface resistance of UHMW-PE film modified by acid with different immersion time and various concentrations and little change of mass by wear testing.…”
