Low density polyurethane elastomer foam with high ball rebound |
| abstract |
The present disclosure provides for a polyurethane elastomer foam formed by reacting a mixture that includes 60 to 50 weight percent (wt. %) of a polyol formulation and 40 to 50 wt. % isocyanate pre-polymer (wt. % based on the total weight of the mixture). The polyol formulation includes 85 to 92 wt. % of a polytetramethylene ether glycol (PTMEG) with a weight average molecular weight of 1900 to 2100 and a hydroxyl number of about 53 to about 60; 4 to 10 wt. % of monoethylene glycol; a blowing agent; a catalyst; and a surfactant (wt. % values for the polyol formulation based on the total weight of the polyol formulation). The isocyanate pre-polymer includes 55 to 70 wt. % of a isocyanate blend having at least 90 wt. % of 4,4′-diphenylmethane diisocyanate; and 30 to 45 wt. % of the PTMEG, where the isocyanate pre-polymer has an isocyanate content of 16 to 21 wt. % based on the total weight of the isocyanate pre-polymer, and the polyurethane elastomer foam has a ball rebound of at least 50% measured according to ASTM D3574 on a 10 mm thickness test plate. |
