Rokopol vTec8020 is a polyether polyol. The product is in the form of a homogeneous, free of mechanical impurities liquid than can opalesce. Rokopol vTec8020 contains antioxidants (excluding BHT) and is characterized by high purity and low emission. The product has a hydroxyl value in the range of 177 -193 mg KOH / g and a dynamic viscosity in the range of 200 - 400 mPas at 25 ° C .
Rokopol vTec8020 can be used for the production of viscoelastic polyurethane foams with a continuous system (slabstock) and batch production (batch). With the use of Rokopol vTec8020 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 70cm. Thanks to its excellent parameters, the product can be widely used in the furniture industry for the production of mattresses and pillows.
The main application advantages of Rokopol vTec8020:
the possibility of producing foams with densities from 40 to 70 kg / m3 and hardness range from 1-3kPa,
application of the product ensures the production of foam with a tensile strength exceeding 80 kPa and an elongation at break above 60%,
foam recovery time 1-10 s,
a minimal impact of temperature changes in the range of 5-40 ° C on the hardness of foam,
increase in hardness at 5 ° C below 50% compared to hardness at 23 ° C,
the possibility of producing foams with an open or closed cell structure,
excellent parameters of permanent deformation enabling high foam compression during transport.
The most common applications of Rokopol vTec8020:
production of viscoelastic polyurethane foams,
in the furniture industry: production of mattresses and pillows with an increased support factor,
production of gel-foams, viscoelastic and elastic foams.
Products made on the basis of Rokopol vTec8020 are characterized by very high quality. Thanks to the refined production process, this polyol has excellent parameters and a wide range of applications.
