Processes Not Suitable For TPVs

* Injection molding on thermoset rubber processing equipment as the temperature requirements are very different

* Plunger injection molding as this does not generate high enough shear conditions to get a consistent material melt

* Rotational molding

* Slush molding

* Dip molding

* Injection molding of foam is difficult to achieve and the maximum density reduction obtainable is 5 to 8%. It is only suitable for the control of sinks in thick parts

* Extrusion on thermoset rubber equipment as the temperature requirements are very different

* Co-extrusion and overmolding with PVC or acetal in the melt state
