Kapton® heaters are a popular type of flexible heaters used in industries such as medical, electronics, aerospace, etc. Kapton® heating solutions are considered the best alternative to mica heaters and silicon heaters in various surface heating applications. Why? In order to understand Kapton® flexible heaters and their applications, it is important to know about the Kapton® material. This post introduces you to the Kapton® material, Kapton® heaters, and their technical capabilities.
Kapton® is a polyimide film manufactured by DuPont, and it offers a wide range of chemical, physical and mechanical properties. This material exhibits great stability across temperatures ranging from −452°F to 752°F, making it an ideal choice for heaters in applications that may be exposed to a wide range of ambient temperatures.
Thin films of this polyimide material are etched with foil circuits to manufacture Kapton® heaters. Thus, these flexible heaters are also known as etched foil Kapton® flexible heaters. The polyimide sheets are 0.003 to 0.01 inches thick and offer excellent dielectric qualities. Kapton® thin flexible heaters are capable of providing 5000 volts of dielectric per 0.001 inches of thickness.
Thin film Kapton® heaters consist of foil elements. Let us discuss the construction of etched foil Kapton® flex heating elements.
These Kapton® heating elements are then placed between thin polyimide sheets and bonded. The Kapton® flexible heaters can be bonded using two different methods:
Along with the types of bonding, the properties of Kapton® contribute to the performance of Kapton® polyimide film heating elements. Let us discuss the properties of Kapton® that make these flexible heaters appropriate for industrial applications.
The significant properties of Kapton® flexible heaters are listed below.
Now that you understand how Kapton® flexible heaters are constructed and are familiar with their technical properties, you should consider buying high-quality Kapton® flexible heaters. To ensure their quality, you should source your heaters from reliable Kapton® heating element manufacturers such as Birk Manufacturing, Inc. The company offers ISO9001, ISO13485, and AS9100-certified industrial heaters. Kapton® flexible heaters are one of their highly sought after products.
