Rokopol vTec770
About product

Rokopol vTec770 is a polyether polyol. The product is in the form of a homogeneous, free from mechanical impurities, liquid that may opalescent. The product contains antioxidants (excluding BHT) and is characterized by high purity and low emissions. The product has a hydroxyl number in the range of 233-252 mgKOH/g and dynamic viscosity in the range of 200-300 mPas at 25°C.

Delivery time up to 14 working days.

Rokopol® vTec770 can be used for the production of viscoelastic polyurethane foams using the continuous system (slabstock) and for periodic production (batch). With the use of Rokopol® vTec770, reactive complementary polyols and appropriately selected additives (catalysts, silicones, foaming agents), it is possible to produce blocks of viscoelastic foam with a rectangular cross-section and a height of up to 70 cm. Thanks to its high parameters, the product can be widely used in the furniture industry for the production of mattresses, pillows and imitations of wood.

Main application advantages of Rokopol® vTec770:

  • the possibility of producing foams with densities from 40 to 80 kg/m3, hardness ranges from 1-3kPa and flexibility up to 55%,
  • the use of the product allows the production of foam with a breaking strength above 50 kPa and a relative elongation at break above 60%,
  • foam recovery time 1-10 s,
  • reduced foam hardness increase effect at low temperatures.

The most common Rokopol® vTec770 applications:

  • used for the production of viscoelastic (viscoelastic) polyurethane foams,
  • polyol used in the furniture industry for the production of mattresses and pillows with an increased comfort factor,
  • used for the production of flexible, viscoelastic and gel foams.

Products manufactured on the basis of Rokopol® vTec770 are characterized by very high quality. Thanks to the refined production process, the product is characterized by very good parameters and a wide range of applications.
