Effect of Silane Curing Conditions on Properties of the Metallocene-Based Polyethylene-Octene Copolymers Compound
- 41 Downloads
A compound was prepared from crosslinking of blend from two type of metallocene-based polyethylene-octene copolymers by different octene content through a two-step silane grafting method (Sioplas process) in a twin-screw extruder. The silane grafted compound was used as wire and cable coatings. The curing condition and specimen preparation method (injection molding and/or extrusion) were factors influenced the hot-set test results at 200 °C. The results of tensile and elongation studies showed a maximum value of 9 MPa for tensile strength and 397% for elongation-at-break after 6 h curing.
