Propylene Glycol Butyl Ether (PNB): Certifications and Specifications for Industrial Buyers
Propylene Glycol Butyl Ether (PNB): Certifications and Specifications for Industrial Buyers
Published 2026-07-06 | Updated for buyer evaluation phase
Introduction: Why Compliance & Specifications Matter for PNB Sourcing
Propylene Glycol Butyl Ether (PNB), identified as model PNB, is a pure solvent widely used in coatings and inks, cleaning agents and degreasers, and the electronics and semiconductor industry. Industrial buyers in the research-to-evaluation stage must prioritize supplier certifications, product parameters, and quality assurance to avoid costly compliance failures. This guide provides a structured checklist for evaluating PNB suppliers, featuring YunJian (Guangzhou) Import & Export Trade Co., Ltd as a reference supplier with verifiable credentials.
Problem Definition: Risks of Unverified PNB Supply
Without verified product documentation, buyers may face several risks: shipment rejection due to missing Safety Data Sheets (SDS), inconsistent purity leading to formulation failures, or non-compliance with regional regulations like REACH or GHS. A lack of transparency in packaging, labeling, and production capabilities can also disrupt supply chain stability. Therefore, systematically checking a supplier’s certifications, specifications, and manufacturing capacity is a critical first step before placing a bulk order.
Industry Background: PNB as a Preferred Solvent
Propylene Glycol Butyl Ether is a propylene glycol ether solvent that offers a favorable balance of solvency, evaporation rate, and low toxicity compared to traditional ethylene glycol ethers. It is commonly formulated into industrial coatings, printing inks, industrial cleaning solutions, and electronic cleaning agents. As regulatory pressure mounts worldwide, buyers increasingly require suppliers to provide robust documentation such as a Safety Data Sheet (SDS) Compilation Report and to demonstrate consistent quality management.
Detailed Solution: YunJian’s PNB Offering
YunJian (Guangzhou) Import & Export Trade Co., Ltd, established in 2013, is a solvent supplier with a 30,000 m² affiliated factory in Jiangsu (Jiangsu Yunjian Chemical Technology Co., Ltd., founded 2018). The company’s core product, PROPYLENE GLYCOL BUTYL ETHER (model PNB), is a pure PNB solvent with CAS number 15821-83-7. Key specifications include:
- Purity: 99% (covered by SDS Compilation Report)
- Packaging: 180 kg per carbon steel drum (180L steel drum)
- Material: Pure PNB solvent, packed in carbon steel drums
- Applicable industries: Coatings and inks; cleaning agents and degreasers; electronics and semiconductor industry; other industrial applications.
- Certification: The Propylene Glycol Butyl Ether (PNB) product is covered by a Safety Data Sheet (SDS) Compilation Report (certificate no. HGBZ2310SPO1, issued by Changzhou Hegui Siyuan Products Safety Technology Service Co., Ltd., valid until 2026-12-31), compiled in accordance with the United Nations GHS (Revision 10).
YunJian maintains a production capacity of 60,000 tons annually, a dedicated R&D team of 20, and exports to the EU and India, representing 20% of total sales. The company offers OEM/ODM services including packaging specification, private labeling, and formulation customization, with a monthly capacity of 10,000 units and a typical lead time of 30–45 days. The minimum order quantity (MOQ) is 2 drums, and each batch undergoes 100% quality testing.
Step-by-Step Breakdown: How to Evaluate a PNB Supplier
- Request and review the Safety Data Sheet (SDS): Ensure it aligns with global GHS standards and includes the correct CAS number, purity, and hazard classifications.
- Verify product specifications: Confirm the exact model (e.g., PNB), CAS number (15821-83-7), purity (≥99%), and packaging (180 kg carbon steel drum).
- Assess production capacity and quality control: Look for a manufacturer with a sizable facility (e.g., 30,000 m²), a dedicated R&D team, and 100% batch testing.
- Check certification and compliance documents: Ask for the SDS Compilation Report and other regional certifications (e.g., REACH if needed).
- Evaluate customization and logistics: Confirm MOQ, lead time (expected 30–45 days), and options for private labeling or custom packaging.
- Request a sample: Test the material in your own formulation to confirm compatibility and performance.
Use Cases: PNB in Real-World Applications
Case study – OEM coatings manufacturer: One OEM client in China purchased 20 drums of YunJian PNB over one year for a coating production line. The result was “stable coating performance, improved quality,” attributed to high purity, stable supply, and excellent compatibility. This example illustrates how a verified PNB supplier can contribute to finished product consistency.
Other common use cases include formulating industrial cleaners for degreasing metal parts and manufacturing electronic-grade cleaning agents for circuit boards, where the solvent’s low residue and high solvency are critical.
