VEF-152 is a 2-part polyurethane foam casting resin system that makes open-cell flexible foam with viscoelastic property with the following attributes for a variety of cushioning and other custom applications.
• The cured foam has a slow recovery after an indentation is made.
• The foam stays flexible at a very lower temperature.
• The component materials are low viscosity liquid at room temperature. The pot-life is above 25 seconds, which allows small amounts to be batched manually.
• The consistency of the foam is easily modified by adjusting the mixing ratios between part-A/B components.
VEF-152 provides a range of foam consistency to be adjusted by varying the mixing ratio between the part-A/ part-B components.
The recommended mixing ratio range is between 100:260 and 100:300 = part-A: part-B by weight. A higher part-B ratio makes foam with slower recovery rate and smaller compression deflection.
This set of properties makes VEF-152 a more user-friendly viscoelastic foam formulation material for manufacturers of custom seat cushions and other specialty products.
