Pentaerythritol CAS 115-77-5
Sinochem is a major Pentaerythritol supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China Pentaerythritol.
Pentaerythritol, white crystal or powder, is flammable and easily esterified with common organic acids. It is widely used in the coating industry to produce alkyd resins, synthetic advanced lubricants, plasticizers, surfactants, as well as raw materials for medicines, explosives, etc.
- Excellent thermal stability – Withstands high temperatures, making it suitable for flame-retardant materials.
- Good chemical resistance – Resistant to acids, alkalis, and solvents.
- Low volatility – Non-hygroscopic and stable under normal conditions.

Properties: White powdery crystals, easily esterified by common organic acids, no reaction when boiled with dilute caustic soda solution. 1g is soluble in 18ml water at 15℃, but soluble in ethanol, glycerol, ethylene glycol, formamide, unless in acetone, benzene, carbon tetrachloride, ether and petroleum ether.
Storage: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Store separately from oxidants and acids and do not mix them. Equip with fire fighting equipment of corresponding types and quantities. The storage area should be equipped with suitable materials to contain leaks. Use plastic bags covered with polypropylene woven bags or sacks for packaging. When the concentration of pentaerythritol dust in the air reaches 30g/m3 or more, it can form an explosive mixture with air and explode when it exceeds 400℃. Therefore, it should be stored in a cool, dry, ventilated place to prevent moisture and fire. Store and transport according to general chemical regulations.
Safety Protection: It may cause irritation to the skin and eyes, and necessary safety measures should be taken when in contact, such as wearing chemical protective gloves and goggles, and avoiding direct contact.
About Us: With over many years as a certified Pentaerythritol manufacturer, we combine innovation with stringent production standards to deliver high-performance product.
