产品用途Applications
季戊四醇是一种四羟基高熔点固态结晶体，主要用于各种醇酸树脂的生产，具有提高强度和改善干燥性的特点。也被用于生产各种酯类化合物，例如粘合剂和油墨的松香树脂、合成润滑油的脂肪酸酯、防辐射丙烯酸酯等。同事季戊四醇还用于生产抗氧化剂。微粉级季戊四醇主要用于生产防火材料和PVC稳定剂。
Penta is a Solid, high-meltingchrystlline material. It is a four-functional polyalcohol with all primary hydroxyl groups. Penta is a key raw material in the production of alkyds, for many types of paint. Penta contributes to good hardness and drying, it is also used in a number of esters, such asrosin esters for adhesives and painting inks, fatty acid esters for synthetic lubricants, and acrylic acid esters for radiation curing. In addition, penta is used in phenolic antioxidants for polyolefines. The micronized form is used in fire-retardant systems and PVC stabilizers
