Manufacturing & Quality Control
Injection-molding production line processing CHIMEI POLYLAC ABS resin.
Consistent supply, batch after batch
CHIMEI POLYLAC ABS PA-757 is supplied in the original 25kg moisture-proof packaging, stored in palletized warehouse stock and loaded into export containers for worldwide delivery. Lot numbers on every bag give full traceability from resin lot to your loading list.
Quality assurance
Each incoming lot is checked against the official TDS - melt flow, color and mechanical retention samples are kept for every shipment, and COA / MSDS / UL 94 documentation ships with the goods on request.

Selection & Differentiation
When to choose PA-757
PA-757 is your default unless the application needs more impact (PA-747/PA-709), flame retardancy (PA-765A), heat resistance (PA-777D) or transparency (PA-758). It is the benchmark every other grade is compared against.
Selection advice
PA-757 vs PA-707: nearly identical rigidity; PA-757 is the more widely stocked export grade with marginally better flow. PA-757 vs PA-757K: PA-757K is the mainland-plant equivalent for local supply.
