Title
(EN) IMPACT PROTECTION FOAM
Abstract
(EN)

An impact protection foam includes the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component includes at least one isocyanate. The isocyanate-reactive component includes from 20 wt % to 80 wt % of a hydrophobic polyol component and from 20 wt % to 80 wt % of a hydrophilic polyol component, based on the total weight of the isocyanate reactive component. The hydrophobic polyol component includes at least one natural oil hydrophobic polyol, and the hydrophilic polyol component includes at least a polyether polyol having a number average molecular weight from 3,000 g/mol to 10,000 g/mol and a primary hydroxyl content of at least 50 wt %. The isocyanate index is from 50-120. The foam article has a rate of energy dissipation less than 35 KN over the temperature range from 10 C to 40 C and a Shore A hardness of less than 55 at both 23° C. and −10° C.
