Product Description:
Silicone
exhibits a wish list of characteristics including superb
chemical resistance, high temperature performance, good thermal
and electrical resistance, long-term resiliency, and easy
fabrication. It also possesses excellent UV and ozone
resistance. Silicone is odorless, tasteless and non-toxic.
Silicone foam is white in color, lightweight and flexible with a
smooth skin on both sides.
Common Applications:
Silicone
foam can be used for insulating and cushioning electronic
assemblies. It can also be used for gaskets, seals, air
filters, thermal shielding, cushioning for aviation, automotive
and locomotive industries as well as flame-retardant
applications. Silicone foam is also approved for repeated food
contact.
Typical
performance of low density, partially open cell silicone foam
rubber. Values are typical of ¼” thick sheet. Not to be used
for specifying.

Note:
Tests, claims representations and descriptions regarding
flammability are based on standard laboratory tests and, as
such, may not be reliable for determining, evaluating,
predicting or describing the flammability of burning
characteristics under actual fire conditions, whether used alone
or in combination with other products. Accordingly, each
potential user should make an individual determination whether
the flammability or burning characteristics of the product are
suitable for the purpose intended by the user.
