C.B.Frost & Co. CBF40
- Chemical Family
- Silicones
C.B.Frost & Co. CBF40 is an inert material and does not react with most chemicals. It operates well under high temperatures of between 60˚C and +230˚C and has excellent resistance to ozone and UV. Due to the inertness of the material, it is ideally suited to several medical applications, and its weathering qualities mean that it is commonly used for a number of industrial purposes. General purpose silicone delivers high performance and a long-life span in extreme high and low temperature.
