Quality Control
PetroChina Jilin Petrochemical Company operates under ISO‑9001 quality management system, implementing full‑lifecycle quality control covering raw material incoming inspection, in‑process monitoring and finished‑product release. Equipped with CMA‑qualified internal testing laboratory, the company sets strict internal control standards higher than national specifications. It adopts 24‑hour real‑time data monitoring, frequent sampling analysis and standardized assessment mechanisms to stabilize unit performance, and has achieved long‑term 100‑percent qualification rate for bulk petrochemical products. Continuous process‑capability improvement projects are carried out for ABS, EPR and SBR grades to reduce batch deviation and secure consistent product performance for downstream manufacturing sectors.
Three-Stage Quality System
Incoming Inspection
Every raw material batch tested against specifications before entering production. Certificate of Analysis verified for all suppliers.
In-Process Monitoring
Real-time process parameter monitoring with DCS systems. Automated sampling and testing at critical control points throughout production.
Final Release
Comprehensive end-product testing against international standards. Batch release only after all specifications are confirmed and documented.
Testing Methods & Standards
Chromatographic Analysis
HPLC and GC-MS analysis for purity, impurity profiling, and molecular identification per USP and EP standards.
Wet Chemistry
Classical titration, gravimetric, and colorimetric methods for assay determination and limit testing.
Physical Testing
Comprehensive physical property measurement including viscosity, density, refractive index, and particle size distribution.
Stability Studies
Long-term and accelerated stability testing per ICH guidelines ensuring product quality throughout shelf life.
Quality Without Compromise
The company links quality control closely with customer‑oriented technical services. When receiving customized application requirements from clients, its quality team conducts targeted process optimization and product quality tackling to match specific processing scenarios. Complete test records and traceable documentation are provided for every batch of goods. Root‑cause analysis will be triggered in case of any quality feedback, promoting iterative upgrade of production formulas and operating parameters. Such closed‑loop quality mechanism supports both domestic large‑scale manufacturing supply and overseas export business of its diversified resin, rubber and chemical intermediate portfolio.
