If you need gaskets for your products, you have several choices. For example, you may wish to use synthetic rubber or perhaps cork. However, foam gasket applications can be an excellent decision and here are some important reasons to consider them.
What are Foam Type Gaskets?
A typical foam gasket can be made from a wide range of materials. This includes polyurethane, neoprene, vinyl, silicone and polystyrene. In order to receive its sponge like properties and appearance, the material goes through a special process.
Why are Natural Sponges Porous and Absorbent?
Sea sponges are invertebrates with soft and porous skeletons. Their cells contain a great deal of air and this makes them highly absorbent. However it’s the cells which give sponges their special properties. Sponges do not really have tissue but their cells are setup to let water pass through and trap tiny food particles.
In order to mimic sponge cellular properties, synthetic rubber or other materials are gas injected during the manufacturing phase. This creates chemical reactions (bubbles) to produce either open or closed cell foams.
Closed Cell
During the process of manufacturing, most cells stay closed and bubbles are not popped (open). This creates a dense foam material and is the most common type used.
Open Cell
Most cells (bubbles) in the foam have been opened or broken. It is softer and more cushioning that closed cell.
Benefits
Foam gasket applications are found in many industries today and here are some of their benefits:
* Insulation – perfect for keeping out the weather.
* Sound dampening
* Prevent air pressure leaks
* Moisture prevention
* HVAC – used for sealing heating and cooling applications
* Protection from contaminants
All Gaskets Are Not the Same
When it’s time to choose a source for your gaskets, go with an experienced company. Also, select a manufacturer with a reputation for quality products and services.
