Performance comparisons and formulation tips for various types of flexible PVC applications

Coated fabrics


Coated fabrics can be produced with plastisol spread coating or extrusion coating. For plastisols, paste viscosity and ageing are key for the quality of the final product and adequate operations. InnoleicTM products are suitable for plastisol applications, but require special atention to ensure proper formulation adjustments to obtain the ideal rheology.

One of the key advantages of the InnoleicTM products, is the high viscosity at low shear and low viscosity at high shear, promoting a uniform spreading of the paste on the fabric (high shear) and a lower penetration into the fabric (low shear), conferring a smooth touch to the final article.

Another interesting characteristic is the higher elongation and higher tensile strength, promoting higher resilience to the material, which can be observed in the touch and a greater elasticity of foams.

Gel Rates

The chart shows the time to gel formation of compounds formulated with different plasticizers. It is clear that InnoleicTM FF presents a much faster gel rate than most traditional plasticizers. But the gel rate of the other materials is fairly similar.

Viscosity Ageing

The chart shows the viscosity ageing (up to 168 hours) of compounds formulated with different plasticizers. As expected, the higher efficiency of InnoleicTM products promotes increased viscosity ageing, except for InnoleicTM E8. This can be adjusted, though, with the proper selection of resins, as demonstrated in the chart below.


The adjustment required to obtain high quality foamed plastisol layers using InnoleicTM is also on the viscosity. The use of different quantities of kickers or foaming agents did not significantly impact the size and quality of the foam cells. The adjustment of viscosities, on the other hand, was very effective to match or even improve cell quality and size of foam layers.
