Rokopol® iFlex S21 is a polyether copolymer polyol based on ethylene oxide (EO) and propylene oxide (PO), produced from glycerin. It is a transparent liquid, free of mechanical impurities, with the addition of BHT-free antioxidants.

It is characterized by a hydroxyl value in the range of 40–46 mg KOH/g and a dynamic viscosity of 1000–1300 mPas (25°C). Rokopol® iFlex S21 ensures excellent process control and repeatability of production parameters.

The product was developed as part of a research and development project co-financed by the European Union through the European Regional Development Fund.

Rokopol® iFlex S21 was developed with modern polyurethane foam production technologies in mind—including continuous (slabstock), batch, and molding processes. It works exceptionally well as a cell opener in the production of Hyper Soft, Soft, HR (High Resilience), visco, and standard foams.When combined with appropriately selected additives (catalysts, silicones, blowing agents), it enables the production of highly elastic foams with a block height of up to 130 cm, while maintaining an ideal structure and mechanical properties.Key advantages of using Rokopol® iFlex S21 polyol:

innovative technology – a modern formula with a high EO content,

very wide process window – easy adaptation to various production processes,

excellent cell opener – effective cell opening without the need for additional agents,

the ability to produce foams with densities of 20–60 kg/m³ and hardnesses of 1.0–2.5 kPa,

elongation at break up to 450% and tensile strength exceeding 200 kPa,

resistance to “scorching”—high thermal stability during the foaming process.

Properties and applications

Properties of foams using Rokopol® iFlex S21 polyol:

possibility of producing foams with a density in the range of 20-60 kg/m³ and a hardness in the range of 1.0-2.5 kPa,
the polyol content in the formulation is 65-80 pph,
height of foam blocks obtained: up to 130 cm (25 kg/m³) / 70 cm (55 kg/m³),
elongation at break up to 450%,
provides a very high comfort factor,
no need to use additives in the formulation,
no sticky touch – the result is a smooth and pleasant to the touch foam with a uniform structure,
excellent resistance to permanent deformation – long-lasting elasticity and comfort of use,
low production costs.

Application:

in the furniture industry – production of Hypersoft, Soft, and HR foams ensuring exceptional comfort of use,
in the automotive industry – comfortable material for car seats and interior elements,
in the production of premium mattresses and pillows – maximum elasticity, durability, and comfort,
as a cell opener in PU foam formulations.
