Rokester 1711 is a polyester polyol. It exists in the form of homogeneous liquid. It has hydroxyl value within the range of 185-195 mgKOH/g and dynamic viscosity within the range of 2500-3500 mPas at temp. 25°C. It is characterised by very low reactivity.
Rokester 1711 is a specialised aliphatic-aromatic polyester polyol. It is used mainly as a polyol component in production of one-component foams (OCF). Owing to very low reactivity and relatively low hydroxyl value it is possible to increase significantly the content of this polyol in a formulation. It significantly improves flame retardant properties of the foam and allows to obtain classification "B2". This product can also be used in a mixture with more reactive polyester polyols. The product is mixed in any proportion with chlorinated paraffins 45 and 52 (most frequently used fillers in the sector of one-component foams (OCF)).
