REVERTÉ’S TECHNICAL CALCIUM CARBONATES AS AIDS IN THE RIGID PVC EXTRUSION PROCESS
Extensive skills at global level in formulating compounds for rigid PVC extrusion have created an opportunity to use new technical calcium carbonates that make it possible to optimise the gelification of PVC during its processing.
These new calcium carbonates do not behave only as mineral filler that makes the finished product rigid but also as rheological additives in the processing of the compounds.
Their use makes it possible to reduce processing aids used to ensure homogeneous fusion of the PVC in the extrusion of profiles and pipes.
All this also results in greater stability in processing, a reduction in surface defects such as plate out in the manufactured units and enhanced mechanical properties in the finished product.
Reverté’s Technical Calcium Carbonates (TCC) are thus highly specialised mineral fillers designed to improve the consistency and stability of processing and optimise the performance/cost ratio of PVC compounds.
