Description
Rokopol G700 is a glycerine-based polyether polyol (polyoxyalkylene triol) in the form of a homogeneous, clear liquid. The product contains antioxidants (excluding BHT) and is characterized by low content of sodium and potassium. The product has a hydroxyl value at 25 ° C in the range of 225-250 mgKOH / g and has a dynamic viscosity of 220-270 mPas. Rokopol G700 is used as a base material for the production of single-component foams (OCF), assembly foams and foaming adhesives. As an additive in the one-component foam formulation, it increases the stiffness of the foam and slightly increases the viscosity of the prepolymer. With the use of Rokopol G700, other polyether polyols and appropriately selected additives (catalysts, silicones, foaming agents) it is possible to produce one-component foam with excellent properties. The product is also used in the production of rigid foams. Due to its outstanding properties, the product is widely used in the construction industry. The main application advantages of Rokopol G700: application of the product provides excellent dimensional stability (shrinkage below 5%); the possibility of producing one-component foam with a density in the range of 10-30 kg / m3 and a hardness in the range of 10-45 kPa, its low molecular weight ensures improved transport of moisture in the foam and reduces foam cutting time to below 25 minutes, low content of sodium and potassium enables longer service life – up to 24 months, the product is characterized by a limited tendency to yellowing, which allows its longer storage.. The most common applications of Rokopol G700: product intended for the production of all-season foams, production of mounting foams for windows, doors, culvert pipes, rings, the product used as foam-plastic for Styrofoam and window sills, production of polyurethane adhesives and sealants. Products manufactured on the basis of Rokopol G700 are characterized by very high quality. Thanks to the refined production process, the product is characterized by excellent parameters and a wide range of applications.
Properties and applications:	the possibility of producing one-component foam, characterized by a density in the range of 10-30 kg / m3 and a hardness in the range of 10-45 kPa; application of the product provides excellent dimensional stability (shrinkage below 5%); low content of sodium and potassium extends the service life (up to 24 months) and limits the tendency to yellowing, which enables longer storage of the product; used in the construction industry for the production of polyurethane adhesives and sealants; used in the construction industry for the production of all-season mounting foams for windows, doors, culverts and rings.
