Anti-Cracking Impact Modifier Masterbatch for ABS/PC, PC, PC/PS and Recycled Plastics

Buyer-facing sourcing profile for a white granular impact modifier masterbatch promoted for ABS/PC, PC, PC/PS and ABS recycled or virgin plastic applications. Key checks before RFQ should focus on exact chemical identity or blend disclosure, CAS/EINECS applicability, grade A-6648 confirmation, active content claim, dosage range, polymer compatibility testing, impurity/filler statement, export documents, HS classification support and packing suitability.

Before matching

Documents to check

  • CAS number, grade, assay, and impurity profile
  • SDS, COA, TDS, HS code, and transport classification
  • Destination-market import documents before supplier matching
Package and route

Packing notes

  • Standard packing listed: 25 kg woven bag
  • Confirm inner liner, moisture barrier, palletization and export carton/bag labeling requirements
  • Request photos of current production packaging and label showing product name, grade, batch number, net weight, manufacturing date and shelf-life or retest date
  • For LCL or sea freight, confirm pallet wrapping, bag strength and moisture-protection measures
  • Ask whether sample packs are available with the same batch COA format as bulk supply
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

  • Impact modification of recycled ABS/PC or PC blends after buyer-side compatibility testing
  • Anti-cracking support for molded plastic parts requiring improved toughness
  • Toughness improvement in injection-molded ABS, PC or PC/PS products
  • Flexibility and cold-impact performance improvement in selected engineering plastic blends
  • Trial formulation work where low dosage impact modifier masterbatch is preferred
How we compare

Sourcing options

  • Request a pre-shipment sample with SDS, TDS and COA before bulk RFQ
  • Ask for grade A-6648 and any alternative grades optimized for ABS/PC, PC, PC/PS or ABS separately
  • Compare standard 25 kg bag supply versus palletized export packing
  • Request supplier application data at 2%, 3% and 4% addition levels for the target resin system
  • Consider third-party inspection and batch sampling for first commercial order
  • Ask for formulation customization only after defining resin type, recycled content, target impact value and processing method
Human review

Compliance notes

  • CAS number is not clearly provided; buyer should request full chemical identity status, whether the product is a mixture, polymeric additive, masterbatch or proprietary formulation
  • Do not rely on marketplace HS code wording; request supplier-proposed HS code basis and verify independently with customs broker
  • Request current SDS in GHS format, COA, TDS, RoHS declaration, REACH SVHC statement and composition disclosure level acceptable for import compliance
  • Confirm whether the product is classified as dangerous goods for air/sea transport; obtain transport section of SDS and any non-DG statement if applicable
  • Verify export eligibility and import requirements for destination market before issuing PO
  • Confirm food-contact, toy, automotive or electrical application suitability only through applicable test reports if such end uses are intended
  • Claims such as 99.9% effective components, no fillers and 40-70% improvement should be validated by batch COA and buyer-side application testing
  • Request heavy metals, ash content, volatiles, moisture and restricted-substance test data if the additive will be used in regulated plastic products
