WebDec 13, 2024 · CTE will be discussed later. Other properties such as modulus and hardness decrease beyond this region. A good analogy to this behavior (though not entirely correct) is the dashboard in your car. At 6:00 am the morning of a hot summer day, your dashboard will be stiff and hard. By midday, after the sun has ... WebJul 1, 2024 · The result is a rapid-cure compound even at room temperatures. The advantages of silicone potting materials are: Elastomeric (flexible and rubbery in the cured state) Stays soft at extremes of temperature (-50°C up to +200°C) Good thermal conductivity. Good for thermal shock, thermal cycling. Good adhesion.

The coefficient of thermal expansion is the ratio of the change in length per degree to the length at 32°F. The coefficient of thermal expansion varies with temperature. The expansion of all rubbers is of the same magnitude, approximately 10 times that of structural steel.
