Key Product Advantages
Superior Dispersion Technology: Treated CaCO₃ and optimized twin-screw compounding prevent agglomeration, eliminating film breakage, surface defects, and weak mechanical spots.
High Filler Concentration Capability: Stable loading capacities ranging from 60% up to 85% maximize raw material cost savings without sacrificing processing stability.
Low Moisture Content: Maintained strictly below 0.15% to prevent bubbling, flow marks, and processing disruptions during high-speed extrusion or injection.
Enhanced Mechanical Performance: Improves product rigidity, tensile strength, heat resistance, and dimensional accuracy across various processing lines.
Batch-to-Batch Consistency: Strict multi-stage quality control guarantees stable physical properties and reliable long-term supply for mass production.
Product Grades & Selection
Standard Grade (60% – 70%)
Ideal for general packaging and standard injection items, ensuring smooth processing.
High Loading Grade (75% – 85%)
Engineered for cost-sensitive mass production to maximize virgin resin replacement.
Custom Grade
Formulated strictly to match specialized mechanical, thermal, or aesthetic specifications.
Target Applications
Plastic Film & Packaging
Used in shopping bags, garbage bags, agricultural mulch films, and industrial packaging to lower resin usage, enhance film stiffness, and improve dimensional stability.
Injection Molding
Ideal for household items, storage containers, crates, and industrial components to increase structural rigidity, reduce cycle-time distortion, and cut material costs.
Blow Molding
Applied in plastic bottles, Jerry cans, and hollow containers to ensure parison stability, consistent wall thickness, and optimum cost efficiency.
Sheet & Profile Extrusion
Suitable for extruded plastic sheets, boards, and construction profiles to improve mechanical strength, dimensional accuracy, and production economy.
Quality Assurance
Raw Material Inspection
Strict laboratory testing of CaCO₃ whiteness, particle size, and carrier compatibility.
Twin-Screw Compounding
Precision thermal extrusion ensures uniform filler dispersion and prevents agglomeration.
Finished Product Testing
Comprehensive checks on MFI, moisture levels, dispersion quality, and appearance before shipment.
FAQ
Q: How does filler masterbatch reduce production costs?
A: Replacing 15% to 40% of virgin PE or PP resin with cost-effective calcium carbonate masterbatch directly lowers raw material expenses while frequently improving product rigidity.
Q: Will high loading masterbatch cause film breakage?
A: No. Shunchang utilizes advanced surface-treatment agents and high-dispersion twin-screw compounding to ensure ultra-fine particle distribution, preventing film tearing and surface defects.
Q: What is the typical addition ratio?
A: Depending on product specifications and film thickness, the typical dosage ranges from 15% to 40%. Our technical team provides tailored recommendations for your specific line.
Q: Do you provide trial samples?
A: Yes. We welcome global buyers and laboratories to request trial samples. Contact our export team to discuss your specification requirements.
