Specification of thisChina White Powder Pentaerythritol 95% Or 98% Suppliers

Pentaerythritol, as a quaternary alcohol, is easy to esterify to produce acids and esters, so it is mostly used as raw materials for alkyd resin coatings, mainly used for building coatings and automotive primers. Pentaerythritol tetranitrate (PETN, Tyne) can be obtained by esterification of pentaerythritol with concentrated nitric acid at 5-15 (?) C in industry. It is a high-performance explosive with higher explosive power than TNT, and is mostly used as booster or mixed with TNT. It was used extensively in the Second World War. Tai En also has the function of vasodilating blood vessels. It is a long-acting vasodilator and can treat angina pectoris. Pentaerythritol rosin ester can be prepared by the reaction of pentaerythritol with rosin acid. It can be mixed with dry oil to obtain a paint with good hardness, water resistance and weatherability. It can be used in varnish, floor ink and so on. An alkyd resin coating can be prepared by esterification and polycondensation of pentaerythritol or glycerol with phthalic anhydride and fatty acid. Using different kinds and different amounts of fatty acids can improve the properties of alkyd resins and make them suitable coatings for various needs. It is widely used as coating on metal and wood surface, and is commonly used for industrial paint and architectural paint in bridges, railways, derricks, housing construction, etc. Because alkyd resin is cheap, raw material is easy to obtain, modification is easy, adaptability is strong and comprehensive, it has developed rapidly since it entered industrial production in 1927, and has become the backbone of the paint industry.

Pentaerythritol is commonly used in paint industry. It is the raw material of alkyd paint. It uses four hydroxyl groups to produce highly cross-linked coatings. This kind of coatings has excellent hardness and color, and can improve the hardness, gloss and durability of coatings film. It is also used as raw material for rosin ester production of varnish, color paint and ink, and as flame retardant, dry oil and aviation lubricant. Pentaerythritol fatty acid esters are polyvinyl chloride plasticizers and stabilizers. They are also used in the manufacture of medicines, pesticides and lubricants.

Pentaerythritol acrylate produced by pentaerythritol and acrylic acid has fast drying property. It is widely used in radiation-curing coatings and fast-drying printing ink to prepare water-soluble alkyd resin. Its polymer can be used as adhesive. Pentaerythritol C6-C10 fatty acid esters are mainly used as advanced lubricants for steam turbines and automotive engines. The ester synthesized with C10-C12 fatty acid can be used as plasticizer of plastics with low volatility and aging resistance; the product can react with epoxy compound and be used as surfactant, widely used in detergents, cosmetics and spices raw materials; the product can also be used as raw materials of explosives, medicines, pesticides and insecticides; organic intermediates, etc.
