Calcium Carbonate filler in a Polypropylene carrier — engineered to reduce resin costs while improving stiffness, dimensional stability, and heat resistance in your PP applications.
Calcium carbonate is the most widely used mineral filler in plastics. In a PP carrier, it delivers measurable improvements to stiffness, heat resistance, and dimensional stability — while significantly cutting your raw material spend.
CaCO3 is substantially less expensive than PP resin. High-loading masterbatch lets you reduce virgin polymer consumption by up to 30% without compromising end-product quality.
CaCO3 acts as a reinforcing filler, increasing the rigidity and structural integrity of PP composites — critical for automotive, furniture, and construction applications.
Minimizes shrinkage and warpage during moulding and extrusion. Essential for parts requiring tight tolerances and precise geometries.
CaCO3 acts as a thermal insulator, improving heat deflection temperature and making the composite suitable for higher-temperature environments.
Improves opacity and whiteness of PP formulations. Masks inherent translucency — ideal for packaging, consumer goods, and aesthetically critical parts.
Pre-dispersed pellet form ensures uniform distribution. Drops directly into your existing PP processing lines — no equipment changes needed.
Bumpers, dashboards, interior trim, and under-hood components. CaCO3-filled PP delivers the stiffness and impact resistance demanded by automotive OEMs.
Rigid containers, bottles, caps, and films. Enhanced rigidity and opacity make CaCO3+PP ideal for cost-effective, lightweight packaging solutions.
Pipes, fittings, profiles, and sheet materials. Improved mechanical properties and weather resistance for indoor and outdoor construction applications.
Chairs, tables, cabinets, and household items. Enhanced stiffness and scratch resistance for durable products with premium aesthetics.
