Product Positioning
1. Mass Production Grade Classification
Liansheng has newly built a dedicated high-purity production line at its Linhai plant in Taizhou, supplying both industrial-grade and electronic-grade ethyl propionate.
The industrial grade is mainly supplied for coatings, fragrances, and general fine chemical synthesis. The electronic grade adopts a multi-stage ultra-pure vacuum distillation process with strict control of moisture, alcohol residues, and trace metal ions, making it suitable for lithium battery electrolytes and semiconductor cleaning materials. Ultra-high-purity laboratory samples can be customized in small quantities, but long-term large-scale supply is not available.
2. Stable Supply Assurance
The company's technical upgrade project plans an annual capacity of 6,000 tons of dedicated electronic-grade ethyl propionate distillation equipment. After commissioning, the plant will operate continuously and automatically throughout the year. Esterification and distillation processes are completed within the plant in a closed-loop system without purchasing crude raw materials, avoiding the impact of external raw material price fluctuations or shortages.

Industry Application Segments
Electronics Industry
• Lithium battery electrode processing: Co-solvent for electrolytes, improving lithium salt dissolution stability and low-temperature discharge performance.
• Semiconductor cleaning: Diluent and cleaning agent for TFT-LCD panels and packaged devices with trace oil contamination.
Pain Point: Ordinary industrial esters contain high impurity levels, which may cause battery swelling and chip leakage defects. Liansheng electronic grade features comprehensive ultra-low ion control and can be directly used in lithium battery and semiconductor cleanrooms.
Polymer Industry
Specialized solvent and diluent for nitrocellulose, UV acrylic resins, and polyimide films, offering strong solvency and moderate evaporation rate with defect-free film formation.
Pain Point: Aromatic solvents are restricted by REACH regulations for export, while ordinary esters often cannot fully dissolve resins. This product is compliant and compatible with various polymer systems.
Fine Chemical Synthesis
Reaction solvent for pharmaceutical antimalarial pyrimethamine synthesis and carrier solvent for agricultural fungicide intermediates.
Pain Point: High-moisture solvents may damage active pharmaceutical structures. This industrial grade provides stable moisture control without secondary dehydration.
Coatings and Adhesives
Diluent for gravure printing inks, wood baking paints, and waterborne polyurethane adhesives, replacing high-VOC aromatic solvents such as toluene and xylene.
Pain Point: Traditional aromatic solvents are prone to customs detention during export. Ethyl propionate is not included in the SVHC list and can be exported compliantly.
Daily Chemicals and Flavors
Raw material for pineapple and tropical fruit flavor formulations and flavor enhancer for candies and frozen beverages.
Pain Point: Low-quality esters often have irritating off-odors. Liansheng's refined distillation process ensures a pure fruity aroma suitable for food flavor compounding.
Compliance and Risk Control
Global Regulatory Compliance
1. US TSCA Compliance: Ethyl propionate is listed in the US TSCA Inventory and does not require additional PMN notification. Shipments will not be detained at US ports for qualification issues.
2. Complete Domestic Certifications: The Linhai plant possesses complete environmental approval documents, hazardous chemical production licenses, and pollutant discharge permits, and has passed ISO 9001, ISO 14001, and ISO 45001 certifications. The plant can support on-site EHS cleanroom audits by lithium battery and semiconductor manufacturers.
Compliance Documents Supplied with Each Shipment
1. Bilingual Chinese-English SDS/MSDS
2. Batch-specific COA quality report with complete GC and ICP raw analytical spectra
3. Copies of manufacturer qualifications and certificate of origin; SGS or Intertek third-party electronic chemical test reports can be provided upon request.

FAQ
Should lithium battery production lines use industrial grade or electronic grade?
+
-
Lithium battery electrolytes and semiconductor cleaning processes must use 99.99% electronic grade. Ultra-low moisture and metal ion levels help prevent battery failure and wafer defects. For inks, fragrances, and general pharmaceutical synthesis, 99.5% industrial grade is more cost-effective. Free comparative samples of both grades are available.
Will there be shortages during peak lithium battery procurement seasons, and can long-term prices be fixed?
+
-
Liansheng operates its own 6,000-ton dedicated high-purity distillation line continuously throughout the year with self-supplied raw materials and separate inventory storage. Annual framework agreements of 1–3 years are supported to lock in prices and delivery schedules, with priority production for electronic industry customers.
Ethyl propionate is volatile. Will specifications deteriorate after long-distance ocean transportation?
+
-
All export drums adopt a double-sealed light-resistant structure that effectively suppresses evaporation and moisture absorption. Under normal 45-day ocean transportation conditions, moisture, residual alcohol, metal ion levels, and COA values remain essentially unchanged and suitable for electronic and coating production use.
