Specifications

RUBBER BALLOON

Inflatable rubber balloon, also called pneumatic rubber air bag, is used for making concrete pre-casting formwork projects in culvert bridge construction.

Pneumatic formwork for in-situ cast of concrete pipes or for making precast elements

Material:

Rubber balloon is made from natural rubber and fabric. in general, rubber balloon is formed by three layers(1+2=2layers of rubber and 1 layer fabric): inner layer is high strength synthetic polymer fabric withstanding the force from concrete and air pressure. Outer layer is vulcanized rubber. Rubber hardness is about 65Shore A to keep its excellent features, such as soft, durable,wear-resistance.

If your concrete slab is thicker, the rubber balloon should be manufactured in 2layers of fabric and 3layers of rubber(2+3).
