Pentaerythritol

Its versatility and consistent quality make it a preferred raw material across multiple industries. Pentaerythritol is available in different grades, including technical grade, nitration grade, and high-purity grade with controlled ash and moisture content. It is extensively applied in the production of alkyd resins, polyurethane resins, epoxy resins, synthetic lubricants, plasticizers, adhesives, inks, coatings, and explosives such as PETN. Chemically, pentaerythritol is a tetrafunctional alcohol composed of four hydroxyl groups, providing excellent reactivity and crosslinking capability. Key technical properties include high melting point, excellent heat and chemical resistance, low hygroscopicity, good solubility in hot water, and strong compatibility with acids and resins. These features contribute to improved hardness, flexibility balance, and long-term stability in finished products.
