Introduction:
PZ expandable swelling rubber water stop strip is sulfided and formed,but different from common rubber products.It features good resilience and extendibility,and also has elastic sealing and water stopping effect.It expands with water and stops water by water,making the water-stop effect more reliable than common water stop materials.

Features:
--It features good elasticity,extendability,swellability and water stopping performance.The swelling rate in water could ajusted between 100% to 500%.swellability rate is not influenced by water quality.

--Has good water stopping performance in wide temperature range and and perfect weather resistance.

--Good water resistance,chemical media resistance and endurance,It has no hazardous matters,no precipitate from dissolving and swelling,and no pollution to environment.

--It could be manufactured into any shape in accordance with end user's requirements,and also be made with common rubber into a composite water proof material.
