Rokester® 2316 is a polyester polyol. It exists in the form of homogeneous, colourless to pale yellow liquid. It has hydroxyl value within the range of 205-235 mgKOH/g and dynamic viscosity within the range of 2000-3500 mPas at temp. 25°C.
Rokester® 2316 is an aromatic modified PA/DEG polyester polyol 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 2316 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. This polyol also has the ability to improve aesthetics of the sandwich panel surface (as compared to the surface obtained using polyol Rokester 2416).
