توضیحات محصول
I.C.C manufactures a wide range of polyether polyols that allow formulators to produce high quality polyurethanes. Polyols contain reactive hydroxyl (OH) groups which react with isocyanate (NCO) groups on isocyanates to form polyurethanes. Polyether triols are formed by propoxylating an initiator (addition of propylene oxide to an initiator). In some cases, the initiator is ethoxylated (addition of ethylene oxide) as well as propoxylated. When polyether triols have ethylene oxide tips, the resulting hydroxyl groups are primary hydroxyls; propylene oxide tips yield secondary hydroxyl groups. Secondary hydroxyl groups react slower than primary hydroxyl groups as a result of the increased steric hindrance. We offer a wide variety of raw materials for the production of molded flexible foams.
Polyol EL6636 is a triol polyether polyol terminating in primary hydroxyl groups. A glycerin and propylene oxide-based polyether polyol triol with ethylene oxide caped. Also, it is 100% active without any amine catalyst and relatively nontoxic.
Polyol EL6636 is a High-performance, low-mono-ol polyether polyol for Molded flexible PU foams.
