Chlorinated Polyethylene CPE Processing Aid / Impact Modifier for PVC Pipe Applications

Public sourcing candidate for overseas buyers seeking a PVC impact modifier or processing aid supplied as white powder. The source listing uses mixed terminology including ACR, acrylic polymers, CPE, and chlorinated polyethylene, so buyers should verify the exact chemical identity, CAS number, chlorine content, polymer grade, and intended PVC pipe formulation fit before RFQ or sampling.

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

  • Listed transport package: 25 kg bag
  • Confirm bag construction, palletization, liner type, moisture protection, and container loading quantity
  • Request export marking details including product name, batch number, net weight, gross weight, origin, and any required transport labels
  • Ask whether samples, trial lots, and full-container shipments are available from the same production grade
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 candidate for rigid PVC pipe compounds
  • Weathering and aging-resistance improvement candidate for PVC products
  • Polymer additive candidate for PVC profiles, fittings, and related rigid products
  • Modifier candidate for ABS or cable applications only after grade-specific formulation validation
  • Distributor stock item for plastics and rubber additive portfolios
How we compare

Sourcing options

  • Request pre-shipment sample with COA matched to the exact batch
  • Start with a trial order after identity and specification confirmation
  • Ask for OEM grade code matching, if replacing an existing CPE or ACR additive
  • Compare at least two supplier lots for chlorine content, volatiles, particle size, and processing performance
  • Use third-party inspection for bag count, labeling, sampling, and COA verification before container loading
Human review

Compliance notes

  • Request COA for each batch with chlorine content, volatile matter, bulk density, particle size, and thermal decomposition temperature
  • Request SDS in buyer-required language and latest GHS classification before shipment
  • Confirm HS code; source page lists 3812200000, but buyer should verify with local broker based on confirmed chemical identity and use
  • Clarify whether the product is CPE, ACR, or another PVC additive before import classification, documentation, or formulation approval
  • Ask for TDS, specification sheet, manufacturing origin, shelf-life statement, and storage-condition statement
  • Confirm DG status for ocean/air transport with SDS and carrier review; do not rely on marketplace text alone
  • Check destination-country polymer/additive inventory status and any PVC, cable, construction, or pipe-sector documentation needs with local compliance counsel
