Polyimide properties:

Polyimide is a kind of high molecular material with good heat and low temperature resistance, good mechanical strength and excellent comprehensive properties. It can greatly improve the temperature resistance of the optical fiber coating layer, extend the service life of the optical fiber in high-temperature environments, and still maintain good mechanical properties without brittle cracking in low-temperature environments.

Polyimide is a self extinguishing polymer, with low smoke generation rate, close coefficient of thermal expansion to quartz material, certain self-lubricating performance, aging resistance, high voltage electrical breakdown resistance, etc., and little air release under extremely high vacuum. Polyimide has high radiation resistance and mechanical properties. It can still maintain high strength in the irradiation environment. It has high tensile, bending and compression strength, outstanding creep resistance and dimensional stability.

Polyimide has non-toxic stability and biocompatibility, and can be used to prepare tableware and some medical consumables. At the same time, polyimide is resistant to almost all organic solvents, some inorganic acids and hydrolysis.

Technological advantages:

High quality coating layer, no deformation at 300 ℃, adjustable thickness of coating layer

Our company adopts a specially designed vertical online thermal curing process plan, which has a wide adjustable range of coating thickness, good concentricity of the fiber optic coating layer, smooth coating surface, no stress concentration points, and significantly improved screening strength;, At the same time, it is cured evenly to reduce glue residue. During our 300 ℃ high temperature thermal shock test, it does not bend or deform, and after a long time of high temperature, it still maintains good bending and tensile strength;

High speed preparation of low loss optical fibers
