Rokopol® vTec 8940 (Polyester-polyether polyol)

Rokopol® vTec 8940 is a mixture of polyester and polyether polyols. It is in the form of a homogeneous liquid, free from mechanical impurities, capable of opalescence. It contains antioxidants (no BHT). It shows high purity and low VOC emissions. It has a hydroxyl value in the range of 140–160 mg KOH/g and a dynamic viscosity at 25°C in the range of 1500–2500 mPas.

The product was developed as part of a research and development project co-financed by the European Union from the European Regional Development Fund.

Rokopol® vTec 8940 is used to manufacture viscoelastic polyurethane foams in a continuous (slabstock) and batch production system. It is used with appropriately selected additives (catalysts, silicones, foaming agents) to produce blocks of viscoelastic foam with a rectangular cross-section and a height of up to 80 cm. The product was developed as part of a research and development project co-financed by the European Union from the European Regional Development Fund. Key application benefits of Rokopol® vTec 8940

Rokopol vTec8940 contains 25% recycled bio-based materials (PET) and natural oils. As a result, when using the optimum formulation, the viscoelastic foam can contain around 15% eco-friendly components,

a simple starting formulation based on TDI80 or MDI,

possibility to obtain foam with very high airflow on standard silicone,

high purity and low VOC emissions,

very open foam structure,

possibility to produce foams with a density in the range of 35–60 kg/m3 and a hardness in the range of 1.0–3.0 kPa,

the tensile strength of the foam is above 150 kPa, and relative elongation at break is over 250%,

a foam recovery time of 5–20 s,

excellent permanent deformation parameters enabling high compression of the foam during transport,

pleasant foam feel.

The most common applications for Rokopol® vTec8940:

viscoelastic polyurethane foams (visco, Memory Foam), elastic and gel foams,

mattresses and cushions with increased comfort factor (furniture industry).
