Surface Appearance

Paper

Use of SOCAL® makes it possible to obtain a better surface aspect: particularly the surface is smoother.

PVC

SOCAL® and WINNOFIL® can also be used in extruded, calandered and injection molded PVC to enhance surface appearance while reducing formulation costs and plate-out and increasing output.

CPCC containing compounds exhibit excellent gloss in extrusion and injection molding applications. In pigmented rigid PVC, CPCC gives an unparalleled degree of gloss as a consequence of its ultrafine particle size and absence of the large particles present in ground fillers that produce surface defects thereby increasing light reflection. Materials sometimes difficult to process such as CPVC (chlorinated polyvinyl chloride) are made more manageable if CPCC is included in the formulation.

The photographs below clearly show the smooth surface finish on the CPCC formulation compared to that with ground calcium carbonate.
The relatively large particles of the latter cause surface defects which increase light scattering.
