Rokopol FS3640
About product

Rokopol® FS3640 is a polyether polyol in the form of a white, opaque liquid. 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 25.0-30.0 mgKOH/g and dynamic viscosity in the range of 4000-6000 mPas at 25°C.

Delivery time up to 14 working days.

Rokopol® FS3640 can be used for the production of flexible polyurethane foams using a continuous system (slabstock) or for periodic production (batch). Using polyol and properly selected additives (catalysts, silicones, foaming agents) it is possible to produce blocks of flexible foam with a rectangular cross-section and a height of up to 120 cm. Thanks to its excellent parameters, the product can be widely used in the furniture industry.
The main application advantages of Rokopol® FS3640:
  • the possibility of producing foams with densities from 20 to 80 kg/m3 with hardness ranges from 5 - 12kPa and elasticity of approx. 30%,
  • the use of the product allows the production of foam with a breaking strength above 40 kPa and a relative elongation at break above 40%,
  • can be used with reactive polymeric polyols for e.g. increasing or decreasing foam hardness.
The most common applications of Rokopol® FS3640:
  • used for the production of flexible foams with increased hardness,
  • used in the furniture industry for the production of mattresses, pillows,
  • used for the production of upholstered furniture where increased foam hardness is required,
  • product used in the automotive industry for the production of cockpits, headliners, steering wheels, body panels, bumpers, seats, headrests and armrests,
  • used as a raw material for the production of sound insulation.
Products manufactured on the basis of Rokopol® FS3640 are of very high quality. Thanks to the refined production process, this polyol is characterized by very good parameters and a wide range of possible applications.
Properties and applications:
  • high purity and low emission;
  • the possibility of obtaining flexible foams with very good density and hardness parameters;
  • compatibility with reactive polymeric polyols allows for the extension of application possibilities;
  • wide application of the product in the furniture, automotive and acoustic insulation industries;
