Foam and Sponge Applications
Foams and sponges are used in almost every industry for a variety of different functions. While foams and sponges are two different material types, they have many similar traits. Generally speaking, foams have an open-celled structure and are plastic based while sponges have a closed-cell structure and are rubber based. However, there are exceptions to those guidelines. Whether you are looking for insulation, absorption, or sealing and gasketing, there is bound to be a perfect product for you.
A Wide Range of Applications
| OEM Equipment: | Shock/impact absorption, shock isolation, gasketing, air/dust/oil/water seals, sound vibration dampening, LCD seals, bumper pads |
| Transportation: | Seats, seals, noise/vibration pads, wiring harness, trunk and door seals, insulation |
| Sports & Recreation: | Viton, Flourosilicone, Duck and Rubber, Diaphragm material |
| Construction: | Electrical box seals, weather stripping, pipe wrapping, lighting fixtures, oil seals |
Things to Think About
When determining which foam or sponge product best suits your application, ask yourself the following:
- What is the application sealing?
- What density does the application require?
- What is the temperature requirement?
- Is there a compression set requirement?
- To which elements will it need to be resistant (chemical, ozone, UV)?
