Tripropylene Glycol(TPG) CAS 24800-44-0 High-Purity Industrial Grade Solvent
Tripropylene Glycol (TPG), with CAS No. 24800-44-0, is a high-performance, versatile, and low-volatility chemical intermediate and solvent. Characterized by its excellent solvency, hydrophilicity, and very low odor profiles, TPG is a critical building block across the polymers, coatings, and chemical formulation industries.
Featuring a multi-functional molecular structure with terminal hydroxyl groups, Tripropylene Glycol exhibits exceptional chemical stability and consistent shelf-life performance. As a premier global supplier, our TPG is manufactured to meet rigorous international purity standards, making it the preferred raw material choice for advanced UV-curable monomers and premium industrial chemical products.
- Outstanding Solvency Matrix: TPG exhibits superior dissolving power for a broad spectrum of organic substances, including natural/synthetic resins, modern pigments, industrial dyes, inks, and essential oils.
- Low Volatility & High Boiling Point: With a high boiling point near 293.4°C, it reduces volatile organic compound (VOC) emissions during processing, providing great formulation stability.
- Excellent Reactive Intermediate: The terminal hydroxyl (-OH) groups enable smooth esterification and etherification pathways, facilitating the synthesis of high-value downstream chemical compounds.
-
Hydrophilic Balancing: Its perfect miscibility with both polar and non-polar substrates allows formulators to couple incompatible ingredients efficiently in aqueous solutions.

- Polyurethane and Polyester Resins: Utilized as a specialized polyol component or chain extender in polyurethane elastomer elastomers and unsaturated polyester resins to optimize flexibility and structural resilience.
- Textile and Plastic Processing: Applied as a lubricating agent, plasticizer intermediate, and chemical coupling agent to optimize substrate processing conditions.
Frequently Asked Questions (FAQ) for Dipropylene Glycol
Q1: What is the main commercial advantage of using TPG over Dipropylene Glycol (DPG)?
A1: TPG offers a higher boiling point, lower volatility, and a unique molecular chain length that imparts superior flexibility and lower shrinkage when reacting into UV-curable polymers, making it far better suited for premium TPGDA synthesis.
Q2: Can your Tripropylene Glycol be used directly in UV-curing ink formulations?
A2: Yes. Due to our stringent color control (≤20 Pt-Co) and low moisture specifications (≤ 0.2), our TPG ensures high transparency and stable reaction rates, preventing premature gelation or color shifting in high-end inks.
Q3: Do you support global export documentation and mixed container loading?
A3: Absolutely. As an established certified factory and bulk supplier, we provide full technical documentation including updated COA, MSDS, and export customs compliance papers. We can coordinate flexible packaging sizes (Drums, IBC Totes, ISO Tanks) to optimize your freight logistics.
