Injection Molding Guide - LyondellBasell
Ethylene copolymers, such as ethylene vinyl acetate (EVA), are made by the polymerization of ethylene units with randomly distributed vinyl acetate (VA) comonomer groups. Chain branching Polymer chains may be fairly linear, as in high density polyethylene, or highly branched as in low density polyethylene. For every 100-ethylene units in the

A Guide to Polyolefin Film Extrusion - LyondellBasell
www.lyondellbasell.comFor homopolymer polyethylenes, the higher the resin density, the higher the degree of crystallinity. High density PE resins have molecular chains with comparatively few side chain branches. This allows the chains to pack more closely together. The result is crystallinity up to 85%. Low density PE resins generally have crystallinity from 35 to 55%.

How to Solve Blow Molding Problems - LyondellBasell
www.lyondellbasell.comWith continuous extruders: n decrease the extrusion rate until rough parisons no longer occur. n change extrusion tooling to a set with longer land length. With reciprocating or accumulator type extruders: n decrease extrusion rates (increase drop time)—but this is generally unsatisfactory because of the decrease in productivity.
