Rigid PVC, Plasticised PVC, Polyolefins, Thermoset Polyester and Engineering Polymers

polimeros

Reverté’s wide range of calcium carbonates covers the usage needs of all types of polymers (thermoplastic,  thermosets, water-soluble, etc.).

They specifically stand out for their high purity and very low abrasiveness, which allows them to be used at a high filler percentage without harming the useful life of machinery used in  processing plastics.

In addition, Reverté’s Technical Calcium Carbonates make it possible to totally or partially replace other higher-cost mineral fillers such as: talc, calcined kaolin, glass fibre, precipitated calcium carbonate and titanium dioxide.

These calcium carbonates have been designed taking into account the plastic processing systems used in the market to maximise productivity.
