PRODUCT OVERVIEW
Product Description
Di-Penta Series Di-Pentaerythritol is a multifunctional polyol supplied as a white crystalline powder. It is available in several purity grades and is used as a functional raw material in resin, lubricant, polymer, coating, and specialty chemical manufacturing.
The material contains multiple hydroxyl groups that make it particularly suitable for the production of alkyd and acrylic resins, polyether systems, synthetic lubricants, PVC stabilizer formulations, and selected flame-retardant materials.
Dipentaerythritol is only slightly soluble in water and is insoluble in ethanol, acetone, and benzene under the referenced product conditions. Its solid crystalline form and controlled composition make it suitable for industrial processes requiring consistent polyol functionality.
The referenced technical specification provides High Grade 95%, First Grade 90%, and Qualified Grade 86% options, with controlled Di-PE content, Mono-PE, Tri-PE, ash, moisture, hydroxyl-group content, and phthalic colour. Final grade selection should be based on the intended application and the technical documentation supplied by the actual PBL supplier.

KEY PROPERTIES
Product Characteristics
White crystalline polyol raw material supplied in controlled purity grades for industrial formulation and synthesis applications.
Provides multiple hydroxyl functional groups that support its use as a building block in resin and polymer manufacturing.
Available in 95%, 90%, and 86% Di-PE grades to support different purity and processing requirements.
Slight water solubility and limited compatibility with several common organic solvents provide a distinct physical profile for controlled industrial processing.
Suitable for alkyd and acrylic resin systems requiring a multifunctional polyol raw material.
Applicable in synthetic lubricant and specialty ester manufacturing where Dipentaerythritol functionality is required.
Can be incorporated into selected PVC stabilizer and flame-retardant material systems according to the required formulation and grade.
Defined quality controls cover Di-PE content, Mono-PE, Tri-PE, ash, moisture, hydroxyl-group content, and phthalic colour.

STORAGE & HANDLING
Handling Guidance
Store in securely closed and appropriately labeled packaging in a cool, dry, and well-ventilated location. Protect the material from moisture, direct sunlight, excessive heat, and contamination.
Keep packaging properly sealed when the product is not in use to help preserve the crystalline powder condition and prevent unwanted moisture uptake.
Minimize unnecessary dust generation during handling and follow appropriate workplace hygiene procedures together with the supplier-specific Safety Data Sheet.
Storage, transportation, and handling requirements should comply with applicable regulations and the technical and safety documentation provided by the actual PBL supplier.
