Propylene Glycol 99% Purity CAS 57-55-6 for Coating & Plastic Processing ISO Certified

Product Specifications

Addressing Purity Fluctuations and Supply Instability in Coating Production with Propylene Glycol CAS 57-55-6

Having supported coating and plastic processing plants across 50+ countries for over a decade, we’ve witnessed how inconsistent Propylene Glycol quality disrupts production schedules—unexpected impurities causing coating adhesion failures, or batch-to-batch viscosity variations leading to costly rework. When raw material prices swing violently, as they have in the Asia-Pacific chemical market, manufacturers face impossible choices between absorbing costs or compromising on ingredient quality.

A Stable and Reliable Propylene Glycol Supply Solution

Our Propylene Glycol 99% Purity CAS 57-55-6 directly addresses these challenges through a vertically integrated supply chain. With a dedicated warehousing center and ISO-certified production processes, we maintain consistent purity levels that minimize副反应 risks in coating formulations. Whether you require kilogram-scale samples for formulation testing or ton-level bulk orders for continuous production, our supply chain resilience ensures on-time delivery even during market volatility.

Typical Industrial Applications

This high purity Propylene Glycol serves as a critical plastic additive and coating processing aid, functioning as a humectant, plasticizer, and solvent in industrial formulations. Its low freezing point and stable viscosity make it ideal for modifying film flexibility in water-based coatings and improving polymer melt flow in plastic extrusion processes. All applications are strictly limited to industrial manufacturing contexts, with no household or consumer use permitted.

Why Key Specifications Matter for Industrial Performance

The 99% purity level of our Propylene Glycol CAS 57-55-6 is not arbitrary—it directly impacts production efficiency and end-product quality. Higher purity reduces the risk of unwanted side reactions that can discolor coatings or weaken plastic structural integrity. The precisely controlled boiling point (184.8±8.0 °c at 760 mmHg) ensures consistent evaporation rates during curing, while the -60℃ melting point guarantees year-round handling stability in cold storage environments. Our standardized 250kg drum and 1,250kg IBC packaging options further streamline inventory management and reduce material waste.

What You Gain With Our ISO Certified Propylene Glycol

Choosing our ISO certified Propylene Glycol means avoiding the hidden costs of substandard materials—rejected batches, production downtime, and failed quality audits. Unlike suppliers with inconsistent sourcing, our Hangzhou production facility maintains rigorous quality control, ensuring each shipment meets the same exacting standards. This consistency translates to predictable formulation results and stable production costs, even as market prices fluctuate. For export-oriented manufacturers, our compliance with international standards simplifies customs clearance and meets global buyer requirements.

Why You Can Trust Our Propylene Glycol Supply

Certificate of Analysis & Documentation

Every order includes a batch-specific COA and MSDS, with test results traceable to our quality control records. For critical applications requiring additional verification, we can provide extended testing data upon request, including impurity profiles and stability studies. All documentation complies with international shipping and regulatory requirements for hazardous chemicals.

Storage & Handling

• Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
• Keep away from incompatible materials, food and feed sources.
• Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
• Follow good industrial hygiene practices. Avoid inhalation and skin contact.
• Refer to MSDS for detailed storage and safety instructions.

How to Place Your Propylene Glycol Order

Initiate your order by submitting a procurement list with required quantities—we’ll provide a detailed quotation including delivery timelines within 24 hours. For first-time customers, we recommend requesting a 25kg sample to validate compatibility with your processes. Once specifications are confirmed, bulk orders can be placed with flexible payment terms, including advance payment options for preferential pricing. All shipments include the necessary customs documentation for smooth importation.
