Nordkalk Enrich is surface treated ultrafine precipitated calcium carbonate (PCC) product with unique dispersibility properties for plastic and rubber applications. The multi-functional product innovation of Nordkalk Enrich has increasingly generated greater attention across the market, creating value in various fields of application in plastics, paints & coatings, adhesives, paper, inks and building materials.
Superior technical performance with higher filler content
Nordkalk Enrich P particles disperse uniformly into matrix creating smooth surface leading high-level gloss. Enrich P enables cost effective solution by higher amount of filling while maintaining the gloss, optical and mechanical performance.
Thanks to its superior product features, Nordkalk Enrich P does not endanger the functionality or technical performance of the application. Nordkalk Enrich P demonstrably gives rise to new development opportunities and enhances technical performance such as abrasion resistance, fire retardation and adhesion.
As a pure, limestone-based product, Nordkalk Enrich P is an environmentally friendly choice for coping with more stringent environmental objectives and advancing sustainable development, such as carbon footprint reduction.
Particle size in application
The customized ultrafine particles (d50% 50nm) disperse homogeneously into plastic matrix enabling high gloss level and good mechanical performance. Filler content can be higher than with conventional fillers, which offers cost reduction.
Enrich particles cover plastic surface uniformly, which intensifies its light reflection, achieving a distinct gloss improvement. Higher gloss and filler content are possible thanks to better dispersibility of Enrich particles compared to other ultrafine calcium carbonate fillers.
