Addolink® THPE

Technical Datasheet | Supplied by Lanxess
1,1,1-tris-(p-hydroxyphenyl)ethane. Used as a crosslinking agent for the production of branched polycarbonates and suitable for both common production processes - the interfacial and the melt process. In the case of the interfacial process it can be added together with the bisphenol and other reaction components to the aqueous phase. With the melt process it can directly be added at the beginning of the process when the reaction components are melted. Can be advantageous if the branching agent is still added at the oligocarbonate stage before the final production of the higher-molecular weight polycarbonate. With branched polycarbonates, a pronounced pseudoplastic behavior can be obtained. Can be used for the production of large hollow bodies by the extrusion blow molding or injection stretch blow molding process(improved stability under load of the parison)or for the production of twin-wall sheets and profiles with single-screw extruders. Almost completely built into the polymer matrix and does not give noticeable discolorations of the end product even after repeated extrusions.
