About Pentaerythritol

Pentaerythritol is an organic compound with the formula C(CH₂OH)₄. Classified as a polyol, it is a white solid. Pentaerythritol is a building block for the synthesis and production of explosives, plastics, paints, appliances, cosmetics, and many other commercial products.

Pentaerythritol is a versatile building block for the preparation of many polyfunctionalized compounds. Derivatives of pentaerythritol are components of alkyd resins, varnishes, polyvinyl chloride stabilizers, tall oil esters, and olefin antioxidants. It can be found in transformer oil, plastics, paints, cosmetics, and many other applications.

Polyester derivatives

Pentaerythritol is a precursor to esters of the type C(CH₂OX)₄. One such derivative is pentaerythritol tetranitrate (PETN), a vasodilator and explosive. The trinitrate derivative is called pentrinitrol (Petrin). The tetraacetate is called normosterol (PAG). The polymer cross-linking agent pentaerythritol tetraacrylate.

Fire retardant

Pentaerythritol is used as a fire retardant, such as in plastics. Produces thick carbon barrier upon heating protecting the surface substrate.

Versatile Raw Material for Industrial Applications

Pentaerythritols multi-functionality as a polyhydric alcohol makes it indispensable in industries such as paints, coatings, synthetic lubricants, adhesives, and plasticizers. Its stability and high purity (minimum 98%) ensure reliable performance and product consistency, even in demanding manufacturing environments. Used primarily as a chemical intermediate, it contributes to formulating products with enhanced durability and efficiency.

Superior Chemical and Physical Properties

This compounds stable crystalline structure, high melting point, and low impurity levels (lead and iron 5 ppm each) make it well-suited for sensitive manufacturing processes. Being odourless, freely soluble in water, and having a neutral pH allows Pentaerythritol to be easily integrated into various formulations, providing flexibility in chemical design and end-product quality.

Safe Handling and Storage

Pentaerythritol is classified as non-hazardous and non-flammable, ensuring safer handling during transportation and storage. Store in a cool, dry, well-ventilated area away from moisture to maintain its technical properties and 24-month shelf life. Available in 25 kg, 50 kg, and jumbo bags, it accommodates different scale operations with efficient packaging options.
