Specification
♦ Environmentally friendly foam which does not use HFC or carbon
dioxide as a foaming agent.
♦ Unmodified even after 2,000 hours of testing by sunshine weather
meter.
♦ No degradation at temperatures up to 150c, even with short heat
resistance to as high as 250c.
♦ Fire retardant without generating halogen based harmful gases
such as HF,HCL,HCN,SO2 and S2S, even in the event of combustion.
♦ 1/3000 of compressive residual strain of chloroprene and
polyethylene foams and 1/60 of that of urethane foams, making
for longer service life.
♦ Superb water repellence, assuring longer periods of heat insulation
than glass wool and urethane foams.
♦ Ten times higher gas permeability than organic foams and no
sweating or steam as associated with urethane foams. Outstanding
durability
Applications:
♦ Vibration isolation
♦ Shoe soles
Usable from –40c up to 200c.
Low compression set.
Shock absorption performance
remains stable.
Durable in any weather.

Point (Hz)
♦ Silicone Gel material with outstanding shock absorption and damping
properties.
♦ Low investment product supporting quality and control environments.
♦ Simply place or insert underneath load to reduce vibrations and protect from
shock damage.
♦ Performance remains the same from –40c up to 200c and after
repeated use (low compression set). Low resonance magnification.
♦ Ozone, UV and chemically resistant.
♦ Check total load and see above table. For 0.3kg add a plate for extra
weight or divide SN-2 to reduce projections. For 10kg load divide SN15
into pieces. For 80kg load use two of SN-50 and divide if needed.
♦ Set up to distribute the load evenly and use a flat surface. Peel off protective
PET film before use.
♦ Custom designs available. For properties –see Silicone Gel Properties
Applications
♦ Precision test and measurement equipment, servers.
Resonance Recommended Warp (mm)
Magnification (dB) Frequency (Hz)
♦ Production control and quality assurance for semi-conductors on
