Best Sealing Materials for Enclosures

When designing an enclosure, sealing the enclosure is a critical consideration, one that must take into account the environmental factors that the enclosure will be subject to.  While the final choice of a sealing material should be made by a professional (such as our materials experts who work in tandem with industrial designers and engineers), here are a few material characteristics to take into consideration.  This is not a conclusive list, so if you have questions, give us a call.

Wide temperature range: Choose a silicone foam such as BISCO Silicone, or a silicone sponge material.

UV/ozone resistance: EDPM, silicone sponge and BISCO Silicone foam are good choices.

C-set resistance: A polyurethane such as PORON (medium or high density), is a good choice, as is BISCO Silicone.

Solvent and chemical resistance: A PVC material is a good choice (although it has a narrow temperature range), as is vinyl nitrile, which also resists petroleum.

Acid/base resistance: Neoprene is a good choice.

Low outgassing: Choose a silicone foam such as BISCO Silicone, a silicone sponge material, or a polyurethane such as PORON (medium or high density).

Superior flame resistance: Choose a silicone foam such as BISCO Silicone.

Low cost: Polyethylene is low cost, but is has a low c-set, low force relaxation and low psa anchorage.

As you can see, choosing the right enclosure sealing material can be quite a challenge.  Our materials experts are here to help you every step of the way.  So give us a call.
