CUSHION MATERIAL AND PRODUCTS USING THEREOF. |
摘要 |
<p>A cushion material consisting of a composite material of a water-swellable high molecular material and a high molecular material of the non-hydrolyzing-type crosslinked structure, becomes more than three times to less than 15 times larger in volume when swollen with water, and has excellent pressure dispersibility and excellent durability. Further, a cushion product is obtained by wrapping the cushion material with a water-impermeable material. More preferably, the high molecular material consists of a rubber material which has a breaking strength of 8 kgf/cm<2> or greater and an elongation at breakage of 500% or more. After crosslinked, the high molecular material exhibits the stress at 300% elongation of 5 kgf/cm<2> or smaller.</p> |
