WebAbstract. The terms thermoplastic and thermoset describe the processability of a material as the temperature is changed. A polymer that becomes plastic and flows on heating, either by reason of crystal melting or by exceeding the glass transition temperature Tg is thermoplastic. This process is reversible and so the material can be processed by ... WebAdditives for thermoplastic and thermoset materials are formulated using the technologies suitable for the processing of the carrier polymer. Additives are generally supplied in granules and can be used both during the compounding or directly during their transformation phase (moulding, extrusion). Additives for VMQ are supplied in HCR form.
