Space-grade silicone foam
22 January 2010
CV-2391 from NuSil Technology is a tough, durable silicone foam that does not require additional processing to reach NASA E 595’s controlled-volatility requirements.
The manufacturer of silicone-based materials for aerospace, aircraft, electronics and photonics industries, has released the first controlled-volatility silicone foam in the industry.
Designed for aerospace, electronics and optic applications where outgassing is a concern, CV-2391 is a low outgassing, room temperature vulcanising (RTV) foam that does not require additional processing to achieve NASA E 595 standards for Total Mass Loss (≤1.00%) and Collected Volatile Condensable Material (≤0.10%).
The open-cell, tough, durable foam uses non-corrosive blowing agents and cures in place. The foam is platinum-catalysed and is designed to cure at low temperatures with the option to accelerate the cure by applying heat.
Considered to be a great candidate for potting, encapsulating, or back-filling, CV-2391 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.
“CV-2391 was developed around outgassing concerns that engineers face on a frequent basis,” said Brian Nash, Vice President of Sales and Marketing. “It provides a unique addition to NuSil’s line of Controlled Volatility (low outgassing) silicones and, at the same time, offers the versatility and benefits of a foam.”
It 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.
