PetroChina Lanzhou Petrochemical produces DFDA-7042 under the UCC (Union Carbide Corporation) gas phase fluidized bed polymerization process \u2014 a technology adopted widely in Chinese LLDPE production for its tight control over comonomer distribution and molecular weight uniformity. Polymerization-grade ethylene serves as the primary feedstock, 1-butene as the comonomer, and hydrogen as the molecular weight regulator. The finished product meets execution standard Q\/SY 1494-2 and is shipped as natural-colored pellets free of black particles and foreign matter.<\/p>\n
Pellet cleanliness specifications for DFDA-7042 are held to \u226410 coloring particles per kilogram and \u22641 striped pellet or angle hair per kilogram. On a blown film line, coloring inclusions and angel hair translate directly into gel defects and surface streaks \u2014 defects that require line stoppage to clear. Controlling pellet quality at the parts-per-kilogram level is not a production formality; it is what keeps a film converter’s uptime intact.<\/p>\n
The 1-butene comonomer architecture in DFDA-7042 places short-chain branches along the polyethylene backbone, disrupting crystallinity in a controlled way. The outcome is a resin that balances film toughness with the melt flow behavior required for stable bubble formation across single-layer and multi-layer blown film configurations.<\/p>\n
BASTONE sources DFDA-7042 from PetroChina’s production network and, as a distributor of products from China’s top three petrochemical producers, can extend that sourcing across multiple supply origins when buyers need grade continuity during scheduled maintenance or production allocation shifts. Every shipment carries a Certificate of Analysis tied to a specific production batch, giving procurement teams a documentation trail they can reference if film quality deviates downstream.<\/p>","protected":false},"excerpt":{"rendered":"
DFDA-7042 is a linear low density polyethylene resin manufactured by PetroChina Lanzhou Petrochemical Company using the UCC gas phase fluidized bed process with 1-butene as the comonomer.<\/p>\n
Optimized for blown film extrusion, DFDA-7042 targets packaging film and agricultural film production where consistent mechanical performance and pellet cleanliness are non-negotiable.
