Rokopol® D450 is a diol, propoxylated propylene glycol of general application. It is used for the production of adhesives, rigid foams and other polyurethane materials in reaction with isocyanate. The product is in the form of a homogeneous, clear liquid containing antioxidants (without BHT). It maintains dynamic viscosity within the range 60-80 mPas at 25°C with high functionality f~2 and hydroxyl value within the range 230-270 mgKOH/g.

Rokopol® D450 is a product that is characterised by low content of water and sodium and potassium ions, which has a positive effect on the stability of prepolymers produced with its participation. The product is not acidified, which extends its application possibilities. The high molecular weight (450 g/mol) provides great freedom in designing solid polyurethane systems with different hardnesses, from flexible (Shora A) to hard (Shora D) materials. The product is widely used in the construction industry as an element of binders, sealants, as well as PUR and OCF foams. The main application advantages of Rokopol® D450:

option of using it in a wide range of applications,

limited content of sodium and potassium ions, and water,

high stability of prepolymers produced using Rokopol® D450,

option of using polyol as an additive reducing viscosity,

the polyol provides good flow of elastomer systems and rigid foam,

the product allows to accomplish very good physicochemical properties of the final product.

The most common applications of Rokopol® D450:

product used as a prepolymer for adhesives and modified MDI,

adhesives, elastomers and two-component sealants of diverse hardness and high hydrolytic resistance,

product used in the production of hydraulic fluids,

polyol used for the production of PUR and OCF rigid foams.

Products manufactured on the basis of Rokopol® D450 are characterized by excellent quality. Owing to a refined production process, this product is distinguished by very good parameters.
