 PZ Water-swellable Rubber Water-stope Rubber Bar
 
Description:
PZ Water-swellable rubber water-stope rubber 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 water-stop effect more reliable than common water-stop material.
Features:
It features good elasticity,extandability,swellablity and water stopping performance.The swelling rate in water could ajusted between 100% and 500%.The swelled volume remains the elasticity and extandability of rubber ,and the swellability of rubber,and the swellability rate is not influenced by water quality.
It still has good water stopping performance in the wide temperature range and perfect weather resistance.
It features good water resistance ,chemical media resistance and endrance;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.
