Low density polyurethane elastomer foam with high ball resilience |
| abstract |
The present disclosure provides a polyurethane elastomer foam prepared by making a mixture comprising 60 to 50 weight percent (wt %) of a polyol formulation and 40 to 50 wt % of an isocyanate prepolymer (wt % based on the total of the mixture). weight) formed by the reaction. The polyol formulation includes 85 to 92 weight percent polytetramethylene ether glycol (PTMEG) having a weight average molecular weight of 1900 to 2100 and a hydroxyl number of about 53 to about 60; 4 to 10 wt% monoethylene glycol; blowing agent; catalyst; and surfactant (the wt% values of the polyol formulation are based on the total weight of the polyol formulation). The isocyanate prepolymer includes 55 to 70 wt % of an isocyanate blend having at least 90 wt % 4,4'-diphenylmethane diisocyanate; and 30 to 45 wt % of all The PTMEG, wherein the isocyanate prepolymer has an isocyanate content of 16 to 21 wt %, based on the total weight of the isocyanate prepolymer, and the polyurethane elastomer foam is measured according to ASTM D3574 on a 10 mm thick test panel The ball rebound rate is at least 50%. |
