Product Description
Inflatable Gasket Material
Once the typical conditions to which the seal will be exposed are known, an inflatable seal made of the appropriate material can be selected. Some of the most widely used sealing materials include butyl rubber, natural rubber, neoprene, nitrile rubber, silicone and polyurethane. Each material has its own advantages and limitations. For example, butyl has very low permeability to liquids and gases, making it ideal for sealing. However, since butyl is a petroleum-based product, it also has poor resistance to hydrocarbon solvents and oils.
Inflatable gaskets are a versatile product that goes well beyond mating face seals. Selecting the correct material is critical to the performance of the seal in a specific application.
We are committed to providing our clients with innovative solutions to the operational challenges they face. Whatever your needs, our qualified engineers will thoroughly evaluate your situation and help you find the elastomer that best meets your performance criteria.

How Inflatable gasket Work
An inflatable gasket also known as a pneumatic seal, is a Silica gel hollow elastic tube designed to form a liquid or airtight barrier between the bracket and the impact surface. Depending on the application, they can be molded into concave, curled or flat configurations.
Inflatable gasket introduce pressurized media from an external source into a hollow sealed cavity.
The inflation pressure causes the seal to displace in three main directions: axially, radially inward and radially outward.
Once fully inflated, the pipe forms a positive seal between the mounting and impact surfaces. When inflation pressure is removed, the seal deflates and retracts to its original "memory" configuration, allowing free relative movement between the surfaces.
The most common medium for inflating seals is air, but various gases, liquids or gels may also be used in some applications. The aeration medium is usually injected into the seal through an installed hose or pipe system.
Why use an inflatable gasket
The most beneficial feature of an inflatable seal is the ability to apply its own sealing pressure. Traditional sealing methods often rely on compressing elastomeric gaskets to create an effective seal between surfaces. This compressive stress typically involves the use of bolts or other clamping methods to maintain the compressive stress. Subsequent clamping and unclamping of the mating surfaces can be inconvenient and time consuming.
Inflatable gaskets, on the other hand, can be replaced in seconds as needed to fill gaps of various shapes and sizes, resulting in a fraction of the time to form the seal compared to traditional sealing methods.
Despite their name inflatable seals, it can be used for applications other than sealing. Some alternative uses include:
* Apply squeezing force to the material to help the object move
* Produces the mechanical force of clamping or clamping
*Used as an expandable brake caliper to stop rotating equipment
* Move objects by applying a thrust similar to an actuator on a conveyor belt
* Grasp and lift objects while inflating
Due to their versatility, inflatable seals are used in a wide variety of industrial applications, including:
*Radiation Barrier
* Bulkhead perimeter seals *Drilling fluid contamination seal
*Chemical barrier
*Underwater facilities
*General manufacturing, sealing and packaging
