Rokopol G441

Rokopol® G441 is used as a base raw material for the production of two-component adhesives and a non-standard raw material for the production of one-component foams (OCF), assembly foams and foam adhesives. This polyol is characterized by very good cross-linking properties, and as an additive in the formulation of one-component foam, it will increase the stiffness, viscosity of the prepolymer and shorten the foam cutting time. With the use of Rokopol® G441 and other polyether polyols and appropriately selected additives (catalysts, silicones, foaming agents), it is possible to produce one-component foam with very good properties. The product is also used as an additive in the production of rigid foams. Thanks to its rich properties, the product is widely used in the construction industry.

Main application advantages of Rokopol® G441:

• the possibility of producing one-component foams with a density in the range of 10-30 kg/m3 and a hardness in the range of 10-45 kPa,
• due to its low molecular weight and appropriate structure, it is a product with high hydrophilicity, which allows for better transport of moisture in the foam and shortening of the foam cutting time, well below 25 minutes,
• low content of sodium and potassium allows for long service life up to 24 months,
• the product is characterized by a limited tendency to yellowing, which allows for its longer storage.

The most common applications of Rokopol® G441:

• the product is intended mainly for the production of winter foams, but it is also possible to use it in all-season foams,
• mainly used in the construction industry for the production of mounting foams for windows, doors, culverts, rings, wires and cables,
• a product used as a foam adhesive for expanded polystyrene and window sills,
• used for the production of polyurethane adhesives and sealants.

Products manufactured on the basis of Rokopol® G441 are of very high quality. Thanks to the refined production process, the product is characterized by very good parameters and a wide range of applications.
