    Application:

    Pentaerythritol is a solid, high-melting crystalline material. It is a four-functional polyalcohol with all primary hydroxyl groups. It is a key raw material in the production of alkyds, for many types of paint. It contributes to good hardness and drying, it’s also used in a number of esters, such as rosin esters for adhesives and painting inks, fatty acid esters for synthetic lubricants, and acrylic acid esters for radiation curing. In addition, it is used in phenolic antioxidants for polyolefines. The micronized form is used in fire-retardant systems and PVC stabilizers.
