titleOfInvention |
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. |
