swellable rubber waterstop bar is sulfided and formed,but it is different from common rubber
products.It features good resilience and extandability,and also has
elastic sealing and water stopping effect.It expands with water
,and stops water by water,making the waterstop effect more reliable
than common waterstop material.
1.It features good elasticity,extendability,swellability and water
stopping performance.The swelling rate in water could ajusted
between 100% and 500%.The swelled volume remains the elasticity and
extendability of rubber ,and the swellability of rubber,and the
swellability rate is not influenced by water quality.
2.It still has good water stopping performance in the wide
temperature range and perfect weather resistance.
3.It features good water resistance ,chemical media resistance and
endurance;It has no hazardous matters,no precipitate from
dissolving and swelling,and no pollution to environment.
4.It could be manufactured into any shape in accordance with end
user’s requirements,and also be made with common rubber into a
composite waterproof material.
