Polyimide-coated permanent magnet fibers (HB-P) have temperature resistance up to 400°C, short-term and 300°C continuous. It is ideally suited for medical and sensing applications, where fibers must be sterilized at high temperatures, or subjected to the curing temperatures of high-performance laminates.

Polyimide is a high-performance polymer widely used throughout the electronics industry. The polyimide coating is chemically bonded to the fiber surface and is a particularly strong, chemically resistant material that provides fiber protection when only 10μm thick. In contrast, a standard acrylate coating must be applied with a 125µm coating of 40µm thickness. diameter fibers.

HB-P is particularly suitable for embedded "Smart Skins" type applications due to its low profile, which helps maintain composite strength by reducing the area of the resin rich zone (RRZ). The relatively thin coating, combined with the high adhesion of the glass polyimide bond, can optimize mechanical strain transfer in fiber sensing systems.

The "bow-tie" polarization maintaining (PM) fiber design of the fiber core is capable of producing more birefringence than any other stressed design. That's simply because it's based on two opposing wedges, which is the easiest and most efficient way to apply pressure to a point.

Advantage:

1. Continuous operation up to 300°C

2. High birefringence (Hb)

3. Short shot length (SB)

4. Strong polarization extinction ratio (PER) maintenance

1. High temperature sensor

2. Downhole sensor

3. Interferometric sensor

4. Medicine

5. Embedded sensors
