AROCLOR 1248 Resistant O-Rings and Seals
Aroclor 1248 is more commonly known as polychlorinated biphenyl, or PCB for short. It is commonly used as a lubricant, dielectric fluid, and as a flame retardant in various industrial applications.
When rubber is exposed to Aroclor 1248, it can cause a loss of flexibility in the rubber due to the chemical reaction. This can lead to cracking, hardening, and swelling. In extreme cases, the rubber can become brittle and break down completely. Additionally, PCBs can cause discoloration of the rubber and reduce its ability to withstand high temperatures.
