Product Description

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 65Shore 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).

Standard specification

1-      diameter from 0.2m to 3m,(round)

2-      total length from 1m to 28m(round)

3-      other specifications are also available according to clients’ request.
