Thermoforming

Masterbatch is key to the production of the sheet material used as the feedstock for the thermoforming process. Inhomogeneities in the cast or calendared sheet not only give an unacceptable appearance, they will also have an adverse effect on the moulded product properties. High-quality dispersion of masterbatch is therefore essential for any extruded sheet which will be used in thermoforming.

Choice of pigment and carriers is critical since thermoforming involves thinning and drawdown: if the masterbatch is incorrect, then part thickness, level of detail and quality of surface finish will be affected and inconsistencies and warpage may occur.
