General silica gel products will have insulation and conductive performance, so how to distinguish conductive silica gel and antistatic silica gel?
The surface resistance value of insulating silica gel products reaches 10 to the power of 12 is the insulation level. (There must be many people think: 10 to the power of 5 is conductive, 5 to 9 is anti static, 9 is insulation.) Recommended product: insulating silicone tube
Conductive silicone rubber is usually defined as a volume resistance within 10 times 9 ohmic centimeters. Conductive rubber is divided into anti-static grade conductive rubber
1 antistatic silicone rubber products surface resistance value of 10 between the power of 5-12 is antistatic level. Up to 10 to the ninth power, 10 to the sixth to the eighth power is permanent but the properties of the material deteriorate, beyond 10 to the ninth power is transient antistatic.
2 conductive silicone rubber products surface resistance value of 10 to the power of 5 is conductive level. The volume resistivity is generally 3 ~ 10 ω ·cm, the relative density is 1.15, the hardness is 60 (Shaw A), the tensile strength is 5.7MPa, and the relative elongation is 265%. It can be mixed with methyl vinyl silicone rubber (raw rubber), white carbon black, conductive filler, structure control agent and organic peroxide. When the volume resistance is below 10 ohm cm, the conductive rubber has electromagnetic shielding function.
