Plastics & Rubber-PVC Pipes

PCC acts as a processing aid in pressure pipe:

Coated ultrafine precipitated calcium carbonate can be included in formulations intended for use in pressure pipe applications where addition of 2-3 phr will improve the processing properties and ensure a more complete gelation.

Plate out is also reduced due to the improved dispersion of lubricants and other additives used in the formulation.

Some specifications limit the inorganic content of such formulations and under these circumstances the limit of addition may be only 1 phr. However even at this level, beneficial processing effects can be observed.
