Rokopol® MS5215 is a dispersion of the styrene-acrylonitrile copolymer in the reactive alkoxylated triol, where the copolymer content is 15%. The product is in the form of a white, clear liquid, and it contains antioxidants (excluding BHT), and is characterized by high purity and low emissions. It has a hydroxyl value within the range 29-32 mgKOH/g, and its dynamic viscosity is 1200-1600 mPas at 25°C.

Rokopol® MS5215 can be used for the production of highly elastic polyurethane foams with a continuous type system (slabstock), the periodic (batch) production, and for the production of moulded foams (moulding). Using both Rokopol® MS5215 and appropriately selected additives (catalysts, silicones, foaming agents), it is possible to produce high resilience slabstock with rectangular cross-section and height of up to 100 cm. With its high parameters, the product can be widely used in the furniture industry, sound insulation and the automotive industry. 

The main application advantages of Rokopol® MS5215:

  • possibility of producing foams with densities from 25 to 80 kg/m3 and hardness ranging from 2-5 kPa and flexibility up to 55%,
  • the use of the product allows to produce the foam with a breaking strength above 50 kPa and relative elongation at break up to 60%,
  • the product can be used together with other polymeric polyols to optimize characteristics, including increasing foam hardness, eliminating the trapezoidal effect of slabstock, increasing slabstockheight and foam openness.

The most common applications of Rokopol® MS5215:

  • production of high resilience (HR) foams with very good parameters,
  • in the furniture industry, it is used for the production of mattresses and pillows as a comfortable material,
  • product used in the automotive industry for the production of seats and head restraints as a comfortable material,
  • product used in the production of elements of sound insulation.

Products manufactured on the basis of Rokopol® MS5215 are characterized by very high quality. Owing to a refined production process, this product is distinguished by very good parameters, and is widely used in the furniture, automotive and sound insulation industries.
