Core Advantages

Optimized Cost Reduction

Partially replaces expensive virgin polymers (LLDPE, LDPE, HDPE, PP) with cost-effective mineral fillers, lowering overall production economics while maintaining necessary tensile and impact properties.

Flexible Loading Capabilities

Customized CaCO₃ loading options ranging from 50% to 80% to match specific manufacturing requirements, from thin-gauge film extrusion to heavy-duty industrial applications.

Exceptional Dispersion Performance

Advanced twin-screw compounding minimizes particle agglomeration, preventing surface blemishes, streaks, or micro-cracks while ensuring batch-to-batch consistency for continuous production runs.

Processing Compatibility

Engineered for smooth bubble stability in film extrusion, enhanced dimensional stability and rigidity in injection molding, and improved tensile strength in PP woven products.

Product Applications

Plastic Film Manufacturing Widely utilized in blown and cast film lines for shopping bags, garbage bags, agricultural mulch films, and heavy-duty industrial packaging, providing high bubble stability, enhanced tensile strength, and reduced resin consumption.

Injection Molding Applied in household goods, storage containers, crates, and technical components to improve dimensional stability, increase flexural rigidity, and lower overall material production costs.

PP Woven Products Optimized for raffia tapes used in woven sacks, agricultural bulk bags, and geotextiles, ensuring improved processing output, tensile consistency, and high mechanical performance.

Extrusion & Sheet Applications Suitable for profile extrusion, sheets, and thermoforming products, delivering smooth surface finishes, uniform wall thickness, and reliable thermal stability during continuous operation.
