Silicone Rubber & Kapton Sheath
Silicone Rubber HeatersSilicone Rubber Heaters are rugged, moisture and chemically resistant and are easily bonded or cemented to heat sinks or other parts to be heated. Temperatures from -80 to 390°F (-62 – 200°C) in a wide range of watt densities are regularly supplied. The thin profile transfers heat quickly because the actual resistance element is so close to the heated part. Silicone Rubber Heaters can be insulated with silicone sponge rubber bonded to one side. Another way to lower radiated and convected heat losses is to apply an aluminized foil surface to the heater back. Very little is added to the overall thickness. A common application of Silicone Rubber Heaters is Wrap Around Drum Heating.
Kapton Heaters are especially thin and light weight, yet resistant to tearing and cuts. Kapton is an organic polymer that has high dielectric capabilities and tensile strength. Temperatures from -328 to 390°F (-200 to 200°C) are possible while providing a high resistance to many solvents, oils, radiation and fungus. Because of very low outgassing properties, Kapton heaters are suitable for use in high vacuum applications. Standard bonding methods can be applied. Being transparent adds to Kapton’s versatility.
