ABSTRACT:
The present invention presents an improved self-sustaining, lightweight honeycomb material made from non-elastomeric, imperforate, air permeable, nonwoven polypropylene or polypropylene/polyethylene blend. The thermoplastic honeycomb material of this invention exhibits anisotropic flexing characteristics providing conformability in three dimensions when flexed. In addition, the honeycomb has improved cushioning, resiliency, squeezability and shape recovery following crush, impact or squeezing. It is energy absorptive, thermally insulative, soft, breathable, compressible, shock absorbent and has low water absorbency making it compatible with moist environments, such as perspiration.
