Armour board
Siddhi Rubber Udyog is resistant, closed cell, polymer based expansion joint filler material for RCC columns, walls and slabs. Its excellent recovery (after compression) makes it suitable product for this applications. It is an exclusive product, designed to be used as expansion joint filler in buildings.
Features & Benefits:
- Closed cell –Negligible water /moisture absorption
- Bitumen free-Non –staining, non –impregnated and non- bleeding. Does not disintegrate
- Easy to use – No crumbs, dust or fibers. Can be cut with knife for easy installations.
- Excellent chemical resistance – Unaffected by alkalis alcohols, detergents, petrochemical products etc.
- Excellent recovery, hence can accommodate joint movement
- Does not discolor sealants or architectural substrates.

Applications:
- structural expansion joint in building
- Building brick and block work
- Isolation joints between adjacent contractions, building, around manholes, drains and other insets in concrete etc.
Providing fixing desired thickness of Armor of dawn color, manufacture by the Siddhi Rubber Udyog thickness built up using minimum 10 mm specifically extruded high performance sheet minimum density 28kg/cu.mt compression strength of 0.21kg/sq.mtr. When tested as per ASTM D 3575, manufacture by the Siddhi Rubber Udyog of 1.4 m x 2mtr. at places per sq.mtr to the casted surface to from the expansion joint . ARMOUR will become one side of the shuttering while the expansion joint is being created.
