I.S.T SKYBOND - Model FOAM -Heat Resistant Polyimide Insulation
SKYBOND FOAM, a product of I.S.T Corporation, is a lightweight, heat-resistant polyimide foam notable for its exceptional insulating properties. Designed for environments exceeding 100°C, SKYBOND FOAM can withstand temperatures up to 330°C, making it ideal for high-temperature applications. Its unique manufacturing process allows for precise control of expansion ratios, enabling customization from light, low-density foam to hard, dense states. This adaptability allows SKYBOND FOAM to be used in various technical applications, such as lightweight radar absorbers when compounded with conductive fillers like carbon. Additionally, its use as core material in sandwich panels enhances structural integrity, offering high resistance to heat, weather, and voltage. The foam's low dielectric constant and loss tangent properties make it suitable for locations subject to radio waves, ensuring minimal energy loss and optimal transmission. These attributes position SKYBOND FOAM as a leading solution in advanced engineering applications requiring a balance of thermal stability, strength, and electrical insulation.
Polyimide Foam with freely controlled density settings
SKYBOND FOAM is a light weight foamed plastic cushioning material which has a maximum heat resistance of 330°C, therefore making it an ideal heat resistant insulating material for use in an environment of over 100°C.
SKYBOND FOAM has a great characteristic in comparison to other polyimide foams. During manufacturing, the expansion ratio can be finely controlled, ranging from soft, light and low density foam to hard and solid state foam.
In addition, componentization (compounding) is available by combining SKYBOND with other materials. As an example of this application, lightweight radar absorbers can be made by dispersing conductive fillers inside foams.

High heat resistance and other excellent properties
Polyimide is at the top of its class in terms of performance among engineering plastic materials.
Polyimide is a well-balanced noncombustible high strength material which has a higher level of chemical, radiation and cold temperature resistance, providing electrical insulation in addition to a heat resistance of 330°C. In addition to these qualities, polyimide foams have heat insulating and lightweight properties.
Due to the unique characteristics of polyimide, SKYBOND FOAM exhibits an extremely low dielectric constant and low dielectric loss tangent, which indicate the degrees of radio wave energy loss as index specific to materials. This product can be appropriately installed in places subject to transmitted radio waves, due to its properties of high radio wave transmission, and lesser energy loss. Below is the graph of the dielectric constant of SKYBOND FOAM, and radio wave transmission property data to thickness.
Lightweight radar absorbers
Compounding SKYBOND FOAM with conductive fillers, such as carbon, can result in the manufacturing of high heat-resistant and lightweight radar absorbers, which can be used to absorb radio waves in specific areas.
Sandwich panel core materials
Sandwich panels are made by putting foam between two sheets of FRP (Fiber Reinforced Plastics). For these foams, polyimide foams are most appropriate, due to their high strength, as well as their high resistance to heat, weather, and voltage.
