Twin Screw Element Wear Effects on Tensile / Flex. Mod.
Hi Shayne, The TME (Toothed mixing element) (a.k.a. ZME in German from WP origination) is a distributive mixing element. It is usually recommended for use with low viscosity polymers or compounds, where it performs with higher distributive mixing efficiency than kneading paddle blocks. If you...- shashak

Electrically and thermally conductive polymer composites
Typical electrical resistivity for most polymers is of the order of 10^12 to 10^14 ohms. Adding amines or quaternary ammonium compounds, phosphate esters and polyethylene glycol ester or inherently ESD polymers that can be compounded into the polymer will impart electrical resistivity in the...- shashak

cleaning injection mold screws & barrels
Everyone has their own methodology and ideas when it comes to purging. It is a choice between degree of purging required, permissable downtime and availability of operators. A) PS resins of low MFI are popular generic purging agents. B) If PS is difficult to clean out, many others try PVC...- shashak
