High Temperature Gaskets For a High Temperature Application in the Fire and Life Safety Industry

Challenge

One of our customers who manufacturers fire and life safety devices was in need of a high-performance gasket that offered not only protection against higher temperatures, but also a material that can withstand the life of the smoke detector.

The Fire and Life Safety industry is a very competitive market for manufacturers. When dealing with the safety of ourselves and others, people are more than likely going to seek out the most dependable products from the most dependable brands. It was extremely important to us that we come up with the best solution possible for our customer.

Solution

We recommended going with Rogers BISCO Silicone HT-800 foam. This material has a recommended constant use temperature of 392 degrees farenheit, perfect for high heat applications.

Also, since the nature of this material does not take a compression set, it was the perfect material for this specific application. BISCO silicones are ideal for sealing, cushioning, vibration isolation, and insulation.

Results

The Rogers BISCO Silicone HT-800 had zero issues during the testing of the application. The compression set resistance allowed for this gasket to withstand the life of the smoke detector.

Being a Preferred Convertor for Rogers, SRP was quickly able to acquire samples, and get prototypes out in a timely fashion.

Solving An Electrical Arcing Issue Using Flexible Electrical Insulation Material

Challenge

A customer of ours that is an OEM providing controls in the commercial building industry had an application issue concerning a circuit board.

They were experiencing unanticipated arcing on the circuit board that was resulting in failures in the controls. Electrical arcing is a luminous discharge of current that is formed when a strong current jumps a gap in a circuit or between two electrodes.

The major concern with the arcing was not only the fact that it was causing the controls to fail, however, the arcing could also cause electrocution to the user, or potentially start a fire.

Solution

With the knowledge that we were dealing with a circuit board application, we understood that electricity wasn’t the only thing to pay close attention to, but also the heat inside the product. We also knew there was minimal space to work with within the control box.

Our solution to combat all these issues was to use FORMEX flexible polypropylene. FORMEX is a flame retardant material that provides superior electrical insulation and barrier protection in various industrial and consumer electronic equipment.

Results

Using the FORMEX flexible polypropylene, SRP was able to create a spacer that provided electrical insulation to protect the circuit board by preventing the arc gap from arcing to the ground plane.

The flexibility and lightweight features of this material made it extremely easy to incorporate into the building of the control box.
