CaCO3 Filler Masterbatch for PE/PP Film, Molding and Nonwoven Applications
Buyer-facing sourcing profile for calcium carbonate filler masterbatch supplied for plastics processing applications such as blown film, injection molding, extrusion, blow molding, pipes, sheets and nonwoven fabrics. RFQs should verify CaCO3 content and CAS 471-34-1 alignment, carrier resin grade, melt/heat resistance range, dispersion performance, migration and light-fastness requirements, food-contact document availability, packing format and export documentation before ordering.

Active filler: calcium carbonate, commonly checked against CAS 471-34-1 for CaCO3 componentPlastic filler masterbatch / CaCO3 filler compoundCandidate for RFQ with specification and document verification
Active filler: calcium carbonate, commonly checked against CAS 471-34-1 for CaCO3 component
Carrier resin: listed as LDPE in attributes; raw text also references HDPE clear pellets, so buyer should confirm actual carrier and compatibility with PE, PP or target resin
Color: white or customized according to buyer requirement
Melt temperature reference: 140 C to 280 C as published by supplier
Heat resistance reference: 220 C to 280 C as published by supplier; separate attribute states heat resistance 6 years, which needs clarification
Light fastness: Level 5 to 7 as published by supplier
Migration resistance: Level 4-5 or >= Level 5 appears in source text; buyer should request the tested standard and result basis
Resin suitability listed: ABS, PS, PP, PE, PET and PA; buyer should validate by trial for the intended resin and let-down ratio
Certifications claimed on source page: RoHS, REACH, ISO9001:2008, ISO14001, ISO50001 and CE; request current certificates and scope

Packing notes
Published transport package: 25 kg/bag
Published package dimensions: 75 cm x 45 cm x 20 cm
Published gross weight: 25 kg per package
Confirm palletization, container loading quantity, moisture protection, bag material and labeling format for export orders
Confirm whether OEM neutral packing, buyer brand label or supplier trademark packing is available
Request batch number, production date and shelf-life or storage-condition labeling on each bag
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Blown film and packaging film where filler loading, dispersion and surface finish must be checked by trial
Injection molded plastic parts requiring cost control and dimensional consistency
Extruded sheets, plates and pipes requiring resin compatibility verification
Nonwoven and wire-drawing applications where processing stability and color consistency are important
Environmentally oriented packaging or building-material applications requiring document-backed formulation checks
How we compare
Sourcing options
Request 1 kg to 5 kg lab sample before bulk RFQ for dispersion, processing and mechanical-property testing
Ask for pilot-lot supply with the same formulation, carrier resin and packing as the intended bulk order
Compare CaCO3 percentage, particle size, MFI impact, whiteness and moisture across multiple supplier quotations
For Vietnam-bound procurement, confirm Incoterms, origin, customs documentation and destination import requirements early
For regulated packaging, source only with lot-specific COA and current third-party compliance documents
Human review
Compliance notes
Request COA for each lot covering CaCO3 content or ash content, moisture, melt flow or processing index, whiteness/color value, dispersion and impurity limits relevant to the application
For food packaging or medical packaging claims, request specific food-contact or hygiene test reports, test standards, issuing lab, validity date and product-grade linkage; do not rely on general marketing statements
Verify RoHS and REACH declarations against the exact formulation, carrier resin, additives and intended market requirements
Confirm whether SDS is available for the masterbatch and whether export classification is non-DG under the applicable transport mode; obtain written DG/non-DG statement where required by forwarder
HS code listed as 38249099; buyer should confirm with customs broker for destination-country classification
TUV Rheinland supplier audit is referenced with report ID MIC-ASR2451042; buyers should verify audit status directly with the issuing platform or TUV channel
Check heavy metals, VOC, phthalates, PAHs, PFAS or other restricted substances if the finished article is destined for regulated packaging, electronics, toys or consumer-goods channels
No regulatory approval or market access should be assumed from the listing; compliance must be confirmed by current documents and destination-specific review
