PNEUMATIC TUBULAR
FORM
Pneumatic tubular form is used for
making concrete pre-casting formwork projects in culvert bridge
construction.
Material:
Pneumatic tubular form is made from
natural rubber and fabric. In general, it 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 *5Shore A to keep its excellent features, such as
soft, durable, wear-resistance.
If your concrete slab is thicker,
it should be manufactured in 2layers of fabric and 3layers of
rubber(2*3).
