Sealing Electronic Enclosures
Sealing Gaskets are used to fill space between two or more mating surfaces, commonly found in electronic, engineering and lighting assemblies. By using sealing gaskets you can protect electronics and create a seamless connection between surfaces.
Here at Materials Direct, we offer a range of Sealing gaskets and custom-cut materials to our clients to fit any size, shape or specification.

Custom Cut Materials
Materials Direct is approaching this market in a way that is easy to order and specify in Electronics across all industries. Customers who need a certain brand of material which may not appear on the site can apply for us to add this stock to the sites portfolio based on potential usage.
Instant Quotes – Purchasing Made Easy
The main problem for design engineers and purchasing has been until now the quick supply of parts as often the custom pad is one of the last items to be specified in the design of an Electronic assembly.
Materials Direct not only provides an instant quote but gives the buyer the offer of uploading their custom design for it to be manufactured within 24hours if the material is in stock.
Sealing LED Assemblies
Sealing Gaskets and LED Sealing Materials are often used for sealing electronic enclosures and protecting LED assemblies from the environment. Care must be taken in LED assemblies as volatile condensables present in some materials can attack the delicate coatings in the LED itself.
This can lead to the LED changing colour and light output rendering the unit unserviceable. LED Sealing materials can be used to prevent this. Sealing electronic enclosures ensures that moisture, dust, and other harmful environmental components can not reach your LEDs.
At Materials Direct, all of our LED sealing materials are LED application safe
Elastomeric Sealing Gaskets
Films and Sheets
A Gasket is usually an elastomer film or sheet that is used in an interface between two surfaces.
An elastomeric gasket is a component that is softer than the sealing surfaces being mated together and deforms under pressure creating a seal between the two surfaces.
They are ideal for filling deformities and micro-voids connecting the two surfaces and can often seal gases such as air or liquids such as water.
At Material Direct we offer a range of Elastomeric films and sheets with properties such as being Electrically conductive, Thermally conductive, Radiation Resistant, and more.
Protecting Your Electronic Assemblies
Environmental factors such as dust, moisture, and temperature should be considered when building your electronic assemblies, and steps should be taken to protect your electronics. Without adequate protection, your design may lack performance or ultimately fail.
By using sealing materials to protect your electronics, you can ensure that your electronics are offered the best protection against outside environmental influences such as chemical and moisture ingress often fatal for your assemblies.
Material Specifications
At Materials Direct, we offer a wide range of sealing gaskets and materials including solid silicone, closed-cell foams, sheets, and films. Therefore whatever the application, we may have the materials to suit. If you require something we currently do not offer please let us know and we can stock it for you.
