CaCO3 + PP Masterbatch
Calcium Carbonate filler in a Polypropylene carrier — engineered to reduce resin costs while improving stiffness, dimensional stability, and heat resistance in your PP applications.
Lower Cost. Better Performance.
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.
Significant Cost Savings
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.
Improved Stiffness
CaCO3 acts as a reinforcing filler, increasing the rigidity and structural integrity of PP composites — critical for automotive, furniture, and construction applications.
Dimensional Stability
Minimizes shrinkage and warpage during moulding and extrusion. Essential for parts requiring tight tolerances and precise geometries.
Enhanced Heat Resistance
CaCO3 acts as a thermal insulator, improving heat deflection temperature and making the composite suitable for higher-temperature environments.
Opacifying Effect
Improves opacity and whiteness of PP formulations. Masks inherent translucency — ideal for packaging, consumer goods, and aesthetically critical parts.
Easy Processing
Pre-dispersed pellet form ensures uniform distribution. Drops directly into your existing PP processing lines — no equipment changes needed.
Where CaCO3 + PP Works
Automotive Parts
Bumpers, dashboards, interior trim, and under-hood components. CaCO3-filled PP delivers the stiffness and impact resistance demanded by automotive OEMs.
Packaging
Rigid containers, bottles, caps, and films. Enhanced rigidity and opacity make CaCO3+PP ideal for cost-effective, lightweight packaging solutions.
Building & Construction
Pipes, fittings, profiles, and sheet materials. Improved mechanical properties and weather resistance for indoor and outdoor construction applications.
Furniture & Consumer Goods
Chairs, tables, cabinets, and household items. Enhanced stiffness and scratch resistance for durable products with premium aesthetics.
