TO FILL LEAKAGE BY VOLUME EXPANSION

l HYDRO-SWELLING RUBBER

l ACT THE SAME FUNCTION AS RUBBER ROLE

l ALWAYS EFFECTIVELY FILLING LEAKAGE BY EXPANSIBLE VOLUME

l TO OFFER DOUBLE GUARANTEE ON SEALING PURPOSE

EXPANSION VOLUME:       HARDNESS:

200-1000 % TO ORIGINAL                   40-60 SHORE A;

ELONGATION:           TENSILE STRENGTH:

400-600 %                                 25-40KG/CM.SQ

STANDARD PRODUCT:

20 x 10 mm (Serial No: EPR2010)                                           

20 x 5 mm (Serial No: EPR2005)

MATERIALS:

The main composition of Hydro-Swelling rubber based by a specific recipe to offer excellent weather-resistant and reliable strength. And the addition of non-toxic Hydro-swelling resin; make the possibilities to expand 3-8 fold in volume upon the retreat of water; never loss exist elasticity and strength with unlimited cycles.

 Given with dual water-stop performance, this only-and-one hydro-swelling rubber when applied in prefabricating concrete unit of underground tunnel, subway, and telecom/electricity cable conduits, and the conjunction of secondary concrete joints. For water stop, gives absolutely through water stop function. It is able to fully adjust itself to meet the environment humidity and take care of the leakage problem, and go through unlimited cycle of expansion and restoration without any failure. This hydro-swelling rubber has been recently wide accepted by contractors, who are highly demanding work quality and appreciate the advantage of Hydro-swelling rubber works. It acts as the must for water stop purpose on underground structures.

 APPLICATION:

To solve water leaking and humid problems effectively.

Acting the same function as Rubber Role plus volume expansible.

To double guarantee on sealing purpose.

Able to apply in pre-fabricating concrete unit of underground tunnel, subway, etc., for the conjunction of secondary concrete joints.
