In vielen Kunststoffsystemen wie z.B. elastischen PVC-Bodenbelägen werden aus den unterschiedlichsten
Gründen anorganische Füllstoffe eingearbeitet. Diese anorganischen Zuschlagstoffe zeigen jedoch keine
nennenswerte Tendenz in die flüssigen Bestandteile eines Plastisols aufgenommen zu werden.
Ohne geeignete Additive ist dies praktisch unmöglich. Für eine optimale Verteilung des Füllstoffs bietet
NEWOS für den Prozessschritt der Dispergierung innovative und markterprobte Prozesshilfsmittel unter
der Bezeichnung NEWOTEC an.
In the injection moulding process TPE pellets are fed into the machine through a hopper and then into a heated barrel. The heat from the barrel turns the material into a liquid resin which is then injected into a closed mould under high pressure. After allowing the molten polymer to cool, the finished part can be removed from the mould.
Injection moulding is a high-volume, high tooling cost process, the advanced properties of our TPE compounds deliver short cycle times allowing parts to be produced at a rapid rate.

Settings
Equipment Conventional injection moulding machine
Compression set At least 2:1. Special screws with short sections and higher compression ratios (3:1 to 4:1) may be good at low screw speeds
Shrinkage Between 1.0% and 2.5% depending on the grade, type of application and location of the gate.
