摘要PCT No. PCT/GB96/01664 Sec. 371 Date Jan. 6, 1998 Sec. 102(e) Date Jan. 6, 1998 PCT Filed Jul. 12, 1996 PCT Pub. No. WO97/02843 PCT Pub. Date Jan. 30, 1997A mouldable product such as a pad which can be selectively transformed between pliable and rigid states is formed of a sealed plastic container which houses a metastable compound such as sodium acetate tri-hydrate, a trigger device for initiating the nucleating process in the compound to render it rigid, and a reinforcing open micro-porous material. The material may be fibrous, e.g., cotton, and stabilizes the product in its rigid state for a comparatively long time.
