BF-2000 Ultra Soft Silicone Foam

Previously called EP-2022, BF-2000 Ultra Soft Silicone Foam (liquid silicone base) has been a nice addition to Stockwell Elastomerics' line of silicone products. With a typical force deflection of 1.5psi required to deflect the material 25%, it is the softest silicone foam product currently offered by Stockwell Elastomerics. BF2000 has excellent rebound (compression set resistance), a wide operating temperature range, is UV resistant and is UL 94V-0 flame rated. These properties lend themselves to cushioning and padding for electronics or dust gaskets. LCD gaskets or touch screen gasket are common applications due to the very low rebound force. Like the vast majority of materials carried by Stockwell, pressure sensitive adhesives (PSA, both acrylic and silicone adhesives) can be applied to one or both sides of the foam.

Also in our Liquid Silicone Foam product line are:

BF-1000 is an Extra Soft Silicone Foam with an open cell structure

HT-870 is a Soft Silicone Foam with an open cell structure

HT-800 is a Medium Silicone Foam with a modified closed cell structure

HT-820 is a Firm Silicone Foam with a modified closed cell structure

HT-840 is an Extra Firm Silicone Foam with a modified closed cell structure

F-12 is similar to BF-1000 except with a fabric finish on one side and slightly courser cell structure

All the above silicon foam products listed are UL94 V0 listed (see specific datasheet for details). For more information on BF-2000 Ultra Soft Silicone Foam or other products offered by Stockwell Elastomerics please contact us at (215) 335-3005 or service@stockwell.com.

Thanks for the tip on this.
What exactly do you mean by "rebound force"?

Much like a traditional spring, the load to compress an elastomer increases with the distance or amount of compression. In a static state the load will equal the rebound force of the spring or in this case an elastomer. Many manufactures publish Compression Force Deflection Curves (CFD curves) which graphically illustrate the force to % of compression. In an earlier blog post I give an example of how to use these curves. http://stockwell.com/blog/2008/07/gasket-compression-pecentage.htm

Thanks for your comment,
Steve
