How can a seal improve the protection of a product during its storage and transport? In industrial applications, small gaps between two surfaces can allow the passage of moisture, dust, or air, in addition to generating unwanted movements and vibrations.
Therefore, correctly choosing sealing materials is an important part of the design of a technical packaging. EPDM is an elastomeric material that can be transformed into foam to develop gaskets, packings, and seals intended for different applications.
Its flexibility and adaptability allow for creating solutions that help maintain uniform contact between surfaces. When additional protection is required, the elastomeric foam can be integrated into the design of containers, packings, and industrial systems.
What is EPDM foam?
It is a material made from EPDM rubber that incorporates a cellular structure. This configuration allows for a combination of flexibility, compressibility, and recovery that can be leveraged in gaskets and seals.
The EPDM stands out particularly in applications where components may be exposed to demanding environmental conditions. The specific formulation and grade determine its final properties, so the selection must be made according to the conditions of each project.
The elastomeric foam can be compressed between two surfaces to occupy irregularities and help form a barrier. Therefore, it can be used to manufacture seals with different geometries and thicknesses.
What is EPDM material used for?
Its applications include gaskets, packings, seals, insulation, and protection of components, among other technical solutions. In industrial packaging, EPDM can be used when it is necessary to create a flexible barrier between a container and its lid or between different components of a system.
In this way, the seals can help improve the closure and reduce the entry of external elements.
Why are industrial seals important?
Industrial seals perform an essential function: controlling the existing space between surfaces that need to remain in contact. In packaging, this can help protect the contents against certain environmental conditions and movements during handling.
A proper design of seals can also help reduce vibrations and prevent direct contact between rigid materials. When elastomeric foam is incorporated, the material's compression ability allows it to adapt to small surface irregularities.
Seals for technical packaging
In a packaging system, the seals must be selected considering the size of the container, the closing pressure, the frequency of opening and closing, and the environmental conditions.
For example, a reusable container for industrial components may require a gasket that retains its properties after multiple cycles. In other cases, the priority may be to protect the contents from moisture or dust.
The choice of EPDM will depend on these conditions and the technical specifications that the final product must meet.
EPDM and elastomeric foam for industrial applications
The main advantage of elastomeric foam for sealing applications is its ability to compress and recover part of its shape. This feature allows maintaining contact between surfaces when there are small dimensional variations.
The EPDM can be especially useful in projects where a combination of flexibility and environmental resistance is sought. Therefore, it can be incorporated in seals for equipment, containers, cabinets, and different protection systems.
Additionally, the foam can be transformed through cutting and die-cutting processes to obtain specific geometries. This allows manufacturing seals adapted to the product design instead of relying exclusively on standard formats.
How to choose an elastomeric foam?
The selection of an elastomeric foam should consider factors such as density, thickness, hardness, compression, recovery, operating temperature, and exposure to moisture or environmental agents. It is also important to analyze the seal design.
A gasket that is too thick can make closing difficult, while a piece that is too thin may not generate the required level of contact. Therefore, price should not be the only selection criterion.
The search for the price of elastomeric foam should be complemented with an evaluation of the expected performance, the required quantity, and the conditions of use.
EPDM or polyethylene foam for sealing?
The EPDM and polyethylene foam are different materials and their selection depends on the function that the piece will have. Polyethylene foam can be used for separation, cushioning, protection, and certain sealing applications.
If the search is how to seal with polyethylene foam, it is important to consider the design of the gasket, the thickness, the compression, and the contact conditions.
On the other hand, elastomeric foam can offer an appropriate compression and recovery response for certain sealing applications. This can make it convenient when the component needs to adapt repeatedly between two surfaces.
The application determines the material
There is no universal material for all seals. A protective packaging project may require different characteristics than a gasket permanently installed in industrial equipment.
Therefore, before choosing between EPDM, polyethylene foam or another alternative, it is advisable to analyze the real operating conditions and performance requirements.
Worldwide Foam: foam solutions for seals
The selection of materials for industrial seals requires considering both the properties of the foam and the conditions of the application. Worldwide Foam offers solutions of technical foams for protection projects, packaging, insulation, and component manufacturing.
The elastomeric foam can be part of different gasket designs and sealing elements, while other foams may be more appropriate for cushioning, separation, or protection.
With a technical evaluation, it is possible to determine if EPDM is the suitable alternative and define the format, thickness, and characteristics necessary to develop the seals for the project. Do you need to develop industrial seals with elastomeric foam?
