Inflatable seal

An inflatable seal is a type of rubber seal that inflates and deflates based on the presence of an inflation source.

How It Works

An inflatable seal can be moulded into a concave, flat or convoluted configuration. Once an inflatable medium is placed between the seal and the force, the seal expands and rounds out to create a firm barrier between a mounting and striking surface. The inflatable seal is uniquely designed to return to its original state once the source of inflation has been removed. This lets the technician move both the seal and the other object freely.

Applications

Inflatable seals can be utilized in an array of industries like electrical, environmental and the military to assist in the following applications to:

1. Squeeze to assist in the movement of materials
2. Produce a mechanical holding force
3. Stop equipment without damaging it
4. Push objects with any degree of force
5. Grip, hold, and lift objects while having the ability to retract the seal out of the way when deflated.
6. Seal off one environment

Materials Used

Many elastomers are combined to create an inflatable seal. Some of the more commonly used materials are:

1. EPDM
2. Silicone
3. Viton

The following fabrics can be used to reinforce the seal:

1. Dacron
2. Kevlar
3. Nomex
4. Nylon
