Nusil Intros Controlled-Volatility Silicone Foam
Controlled-volatility silicone foam.
Carpinteria, CA — NuSil Technology has introduced what it calls the first controlled-volatility silicone foam in the industry. Designed mainly for aerospace, electronics and optic applications where outgassing is a concern, CV-2391 is a low outgassing, room temperature vulcanizing (RTV) foam that does not require additional processing to achieve NASA E 595 standards for Total Mass Loss (less than or equal to 1.00 percent) and Collected Volatile Condensable Material (less than or equal to 0.10 percent).

The product is an open-cell, tough, durable foam that uses non-corrosive blowing agents and cures in place. The foam is platinum-catalyzed and designed to cure at low temperatures with the option to accelerate the cure by applying heat.

Considered an excellent candidate for potting, encapsulating, or back-filling, the foam offers several benefits including shock and vibration dampening, increased fuel economy due to lighter loads, reworkability, and protection of fragile electronic components from dirt and debris. It can also be cured in place as space filler, molded into rods, or in some cases, cast into foam sheets for die-cutting gaskets. The soft, compliant quality of CV-2391 provides an excellent seal when used for gaskets because the silicone foam can conform to the topography of surface interfaces while maintaining its general shape.

The material is available in a two-part, hand-mixable kit that yields a soft, white, low-density foam that fully cures at ambient temperature and humidity in 60 minutes.
