Pentaerythritol (Mono grade)

Formula: C(CH₂OH)₄ GOST/CAS: ГОСТ 9286-89 / CAS 115-77-5

Pentaerythritol (Mono grade) is a white crystalline powder, which is a polyhydric alcohol (tetraol). In the industrial sector, it serves as a crucial basic raw material for the synthesis of various complex chemical products. Due to its symmetrical structure and the presence of four primary hydroxyl groups, monopentaerythritol exhibits high reactivity and is widely used in the production of paints and varnishes, synthetic oils, and as a key component in fire-retardant systems.

Applications

Production of coatings and synthetic resins: It is a key component for the synthesis of alkyd resins, polyesters, and polyurethanes. It significantly improves the gloss, hardness, drying speed, and weather resistance of paint and varnish coatings.
Fire-retardant materials (intumescent paints): Widely used as a carbonizing agent (carbon source) in intumescent fire-retardant coatings for metal structures, wood, and cables.
Synthetic lubricants: Used in the production of pentaerythritol esters, which serve as a reliable base for high-temperature aviation turbine oils and industrial lubricants.
Chemical synthesis: Applied in the production of rosin esters, plasticizers (for PVC), antioxidants for plastics, stabilizers, and polyurethane foams.

Key Advantages

Improvement of physical and mechanical properties: Significantly increases hardness, moisture resistance, heat resistance, and the overall durability of final polymer and paint coatings.
High purity (Mono grade): The high content of the main substance (monopentaerythritol) ensures predictability, stability, and maximum efficiency of chemical reactions during synthesis.
Efficiency in fire protection: Acts as an excellent agent in intumescent fire protection systems, forming a dense, heat-insulating char foam when exposed to high temperatures.
Versatility: Finds application in a wide variety of knowledge-intensive and industrial sectors — from construction chemistry and printing to aviation and mechanical engineering.

Storage & Transportation

  • Store in tightly closed original packaging in covered, dry, and well-ventilated warehouses, away from sources of moisture (the product is hygroscopic).
  • No special temperature regime is required, but direct contact with open flames, strong heating, and strong oxidizers should be avoided.
  • The guaranteed shelf life is 12 months (1 year) from the date of manufacture (subject to compliance with storage conditions).
