Modified low-density polyurethane foam body |
| abstract |
A low-density, open-cell flexible polyurethane foam body that is modified to impart resilience and enhanced shock-absorbency properties thereto. Modification is effected by implanting in the open cells of the body expandable microspheres having particle sizes in the micron range, each microsphere being formed by a gas proof polymeric shell encapsulating a drop of liquid isobutane. The microspheres are expanded by heat to more than fifty times their initial volume and are entrapped in the open cells of the body. The expanded microspheres are constituted by a soft polymeric shell enclosing a compressible gas, the expanded microspheres behaving as miniature springs dispersed throughout the body. |
