Pentaerythrital
Water paint Flame Retardant 95% Pentaerythritol 98%
Pentaerythritol Product Description
1. Product Overview
Pentaerythritol (CAS No.: 115-77-5) is a polyhydric alcohol with the molecular formula C(CH₂OH)₄ and a molecular weight of 136.15 g/mol. It is a white crystalline powder widely used in industrial applications due to its high thermal stability and versatile reactivity.
Structural Formula:
HOCH₂ | HOCH₂—C—CH₂OH | CH₂OH
2. Physical & Chemical Properties
Appearance: White crystalline powder or granules.
Melting Point: 260–262°C (decomposes).
Solubility:
Soluble in water (6.8 g/100 mL at 20°C).
Slightly soluble in ethanol, acetone, and glycerol.
Insoluble in non-polar solvents.
Density: 1.396 g/cm³.
Stability: Stable under normal conditions; hygroscopic (absorbs moisture in humid environments).
3. Applications
Pentaerythritol is a key raw material in the production of:
Alkyd Resins: Used in paints, coatings, and varnishes for enhanced durability.
Synthetic Lubricants: Improves thermal and oxidative stability.
Explosives: Serves as a precursor for pentaerythritol tetranitrate (PETN).
Plasticizers: Enhances flexibility in PVC and other polymers.
Flame Retardants: Used in fire-resistant materials.
Pharmaceuticals: Intermediate in drug synthesis.
4. Packaging & Storage
Packaging: 25 kg woven bags with inner polyethylene liners or customized bulk packaging (e.g., 1,000 kg pallets).
Storage: Keep in a cool, dry, and well-ventilated area away from direct sunlight and moisture. Avoid contact with strong oxidizers.
Intumescent Flame Retardant System: APP/MPP/PER Synergy
The ammonium polyphosphate (APP), melamine polyphosphate (MPP), and pentaerythritol (PER) ternary system represents a highly efficient halogen-free intumescent flame retardant (IFR) widely used in polymers, coatings, and textiles. This eco-friendly formulation operates through a synergistic mechanism to suppress combustion by forming a thermally insulating char layer.
CAS: 115-77-5
MF: C5H12O4
Packing: Inner double PE bag; outer cardboard drum or plastic woven bag,Class III package.
Storage: In a cool, ventilated, and dry room, avoid exposure to sunlight, rain, or heat and fire sources.
