Product Description
Refined 99.5% technical-grade glycerin (glycerol, C₃H₈O₃) produced for industrial applications. This product is supplied as a technical/industrial grade material and is not represented as USP grade.
With a 290°C boiling point, very low vapor pressure, and no OSHA hazard classification, it is suited to formulations and processes where a high-boiling, low-volatility polyol is needed. Customers should determine suitability for their specific application and regulatory requirements.
- One Feedstock, Many Chemistries
- Not Hazardous Under OSHA
- High Boiling, Very Low Volatility
- Humectant with Full Water Miscibility
- Certificate of Analysis Available Per Shipment
Applications
Industrial Formulation
Plasticizer for films and coatings; printing inks; textile and fiber lubricants; antifreeze and heat transfer fluids; cement and concrete grinding aids
Chemical Intermediate
Alkyd and polyester resins; polyether polyols for polyurethanes; glycerol esters and mono/diglycerides; epichlorohydrin and propylene glycol feedstock
Laboratory & Process
Solvent and carrier; viscosity standard
Paper, Foam & Packaging
Softening and conditioning of paper and cellophane; flexible foam polyol component; adhesive and sealant modifier
Benefits
- Not Hazardous Under OSHA: Not hazardous under OSHA 29 CFR 1910.1200 (2024) and not regulated as dangerous goods by DOT, IATA, or IMDG.
- High Boiling Point: Boils at 290°C (554°F) with a flash point above 199°C (390°F).
- Very Low Volatility: Vapor pressure below 0.0025 mmHg at 50°C.
- Full Water Miscibility: Fully water soluble, which simplifies dilution, blending, and cleanout.
- Strong Humectant Properties: Hygroscopic, with strong affinity for water.
- Reactive Across Alcohol Chemistry: Three hydroxyl groups support esterification, etherification, and polyol routes.
- Single Feedstock, Multiple Use Cases: One material for solvent, plasticizer, carrier, or intermediate needs.
- COA Available: A Certificate of Analysis can be provided for each shipment. Samples and technical information are available for customer qualification.
