Stat-Tech™ electrically conductive compounds are specifically engineered to provide antistatic, electrostatic discharge (ESD) and EMI/RFI shielding performance for critical electronic equipment applications. These compounds combine the performance of select engineering resins with reinforcing additives such as carbon powder, carbon fiber, nickel-coated carbon fiber and stainless steel fiber for low to high levels of conductivity, depending on the application requirements.
Additional benefits and features of Stat-Tech compounds vary depending on the reinforcing additives used, such as carbon powder, carbon fiber, nickel-coated carbon fiber and stainless steel fiber. A variety of base resins can be used to create Stat-Tech compounds. Stat-Tech compounds are a top choice for applications in the transportation, electrical and electronic, and healthcare industries.
The primary benefits of Stat-Tech compounds compared with fabricated metal and coatings include:
- Lower cost compared with machined components, lower shipping cost
- Reduced weight
- Less susceptibility to scratches, chipping and dents
- Inherent corrosion/oxidation resistance
- Design flexibility
- Part consolidation
Electrically conductive compounds are typically evaluated by measuring the surface resistivity (SR) in ohms/sq. The lower the value, the more conductive the material will be. Typical material classifications follow:
- Anti-stat compounds in the 109 to 1012 ohms/sq performance range minimize generation of triboelectric charges and protect against electrostatic discharge from human contact.
- Dissipative compounds in the 106 to 109 ohms/sq range protect against electrostatic discharge from human contact.
- Conductive compounds in the 102 to 105 ohms/sq range are capable of dissipating triboelectric charges.
- EMI/RFI shielding compounds in the 100 to 102 range can be used to absorb and reflect electromagnetic and radio frequency interference.
