Rokopol® vTec 770 is a polyether polyol. It exists as a homogeneous liquid free of mechanical impurities, which may be opalescent. It contains antioxidants (excluding BHT). It has hydroxyl value within the range of 233-252 mgKOH/g and its dynamic viscosity is within the range of 200-300 mPas at temp. 25°C.

Rokopol® vTec 770 is used for production of viscoelastic polyurethane foams using the continuous system (slabstock) and for periodic production (batch). Using Rokopol® vTec770, reactive supplementing polyols and properly selected additives (catalysts, silicones, foaming agents), viscoelastic blocks of rectangular cross-section and height up to 70 cm can be produced. Main advantages of application of Rokopol® vTec 770:

possibility to manufacture foams of density within the range 40-80 kg/m3 and hardness within the range 1-3kPa, and elasticity up to 55%,

tear resistance of the foam is above 50kPa and relative elongation at rupture above 60%,

foam recovery time 1-10 s,

reduced foam hardness in low temperatures.

Most popular applications of Rokopol® vTec 770:

viscoelastic foams (Memory Foam) and polyurethane foams,

high comfort mattresses and pillows,

flexible and gel foams.

Properties and applications
