Water-absorbing polymer Jastop is an innovative water blocking material with the highly useful property of absorbing water and swelling over a short times.
The polyester nonwoven bag is filled with a specialty water absorbent and swells on exposure to water in less than 1min. When water invades homes or underground malls, during long rains or the downpours of typhoon season, or due to waterway accidents, it can serve the same purpose as a sandbag of forming a dam.
Sandbags are conventionally used in these applications, but in practical terms sand must be stored at these locations to enable the sandbags to be prepared within a short period of time. There are disadvantages in producing sandbags, both in that their weight can hinder their use in water blocking operations, and also the need for large spaces to store the sand.
Jastop is lightweight and compact and does not take up large storage space, moreover a very short time is required for the absorption of water and swelling to form the water-blocking bag to prevent the penetration of water, and furthermore it is an advanced flood prevention material with exceptional handleability that largely obviates the problems with sandbags.
