What is Open Cell Foam?
Open cell foams are commonly used between component panels where a degree of separation is needed to dampen or prevent vibration, as a thermal insulation barrier and to protect against contamination, but where a measure of airflow is still necessary, such as with electronic components where air flow helps keeps components cool.
