PP/PE Toughening Impact Modifier Masterbatch A-669K for Recycled Plastic Compounding
Candidate sourcing page for a white granular PP/PE flexibilizer and impact modifier masterbatch marketed for recycled and virgin plastic compounding. Buyer review should prioritize identity confirmation because the listed CAS No. is not meaningful, plus verification of polymer carrier, active content claim, dosage range, compatibility with target resin, impurity or filler profile, and export documentation readiness.

How we compare
Sourcing options
Request a verified sample with SDS, TDS, and COA before commercial RFQ
Ask for resin-specific versions if processing PP, PE, TPU, PVC, TPR, EVA, or mixed recycled feedstock
Run side-by-side trials at 2%, 3%, and 4% addition against current impact modifier
Request custom formulation support only after disclosing target resin, MFI, application, and required test standard
Compare against alternative polyolefin elastomer, compatibilizer, or impact modifier grades depending on application requirements
Source through export-ready supplier able to provide batch traceability and destination-market documentation
Human review
Compliance notes
CAS identity is not adequately disclosed in the source listing; overseas buyers should request SDS, TDS, COA, and full composition disclosure under NDA where required
Do not treat REACH/RoHS claims as confirmed until current declarations, SVHC statement, and third-party reports are reviewed
Confirm HS code, country of origin, export classification, and whether the material is non-DG for sea/air shipment based on SDS Section 14
Request impurity and restriction checks relevant to plastics applications, including heavy metals, halogens where applicable, phthalates if required, VOC/odor, ash, moisture, and prohibited substances for the destination market
For food-contact, medical, toy, automotive, wire/cable, or regulated consumer goods, obtain application-specific compliance evidence; supplier listing alone is insufficient
Verify whether the product contains elastomer, compatibilizer, plasticizer, processing aid, recycled content, or proprietary polymer blend that may affect customer declarations
No regulatory guarantee is implied; final import and use compliance should be confirmed by buyer’s qualified compliance team

Questions to confirm
What is the correct chemical identity or composition category for grade A-669K, and why is CAS No. shown as AA/unavailable?
Can you provide current SDS, TDS, COA, REACH/RoHS declarations, SVHC statement, and third-party test reports for the exact grade?
What is the carrier resin or base polymer, and is it optimized separately for PP, PE, PPR, TPU, PVC, TPR, or EVA?
How is the claimed 99.9% effective substance content measured, and what impurities or fillers are included or excluded?
Can you provide ash content, moisture, melt flow index, density, volatile content, heavy metals, and CaCO3/filler test data?
What performance test method supports the claimed 40-70% improvement in impact strength, compatibility, flexibility, or softness?
What dosage is recommended for recycled PP/PE with variable MFI and contamination levels, and can you support lab trials on buyer-supplied resin?
Does the grade affect tensile strength, stiffness, heat resistance, shrinkage, color, odor, printability, or long-term aging?
