High Temperature Resistant Fiber

The maximum temperature of ordinary optical fibers is generally not allowed to exceed +85℃.If the temperature exceeds normal usage for a long time,the fiber coating will deteriorate,which has a bad influence on Fiber strength and service life.

We can provide 150℃ and 300℃ resistant fiber,which could be used for high temperature communication and sensing application. The High temperature resistance is promoted by using special coating material and special design of coating die and curing process. The temperature resistant polyester or polyimide fiber can meet the performance requirements of 150℃ and 300℃.

Characteristics:
  • Temperature resistant polyester& polyimide coating
  • Stable performance at high temperature
  • Precise control on fiber geometry
  • Stable optical and mechanical properties
