Rokester® 2416 is a polyester polyol. It exists in the form of homogeneous, colourless to pale yellow liquid. It has hydroxyl value within the range of 225-245 mgKOH/g, and dynamic viscosity within the range of 2500 - 4500 mPas at temp. 25°C.
Rokester® 2416 is an aromatic, modified PA/DEG (phthalic anhydride /diethylene glycol) polester polyol of “Industry standard” for production of sandwich panels with PIR core and PUR/PIR in metal lining, using continuous method. It is dedicated to auto-formulations. Owing to its unique features it can be used as the only polyol component in PIR (polyisocyanurate) formulation without addition of other polyesters or/and polyethers. It contains flame retardant.
High ability of the polyol Rokester 2416 to create a stable emulsion with pentane isomers need to be emphasised. This has significant impact on the quality of the cell structure of the core and on aesthetic values..
