Polyol Chain Extenders
Tri-iso distributes a wide range of polyols that allow formulators to produce high quality polyurethane elastomers. Polyols contain reactive hydroxyl (OH) groups which react with isocyanate (NCO) groups on isocyanates to form polyurethane elastomers. There are several key characteristics which define what performance properties a given polyol will impart in a given polyurethane elastomers. These characteristics include: the type of polyol selected (polyether or polyester), the hydroxyl number or hydroxyl value (OH value), OH equivalent weight, molecular weight, and the functionality of the polyol.
