Stat-Tech™ the conductive plastic undergoes the special engineering design, has the anti-static electricity and the static discharge (ESD) the nature, may use in the key the device. These compound unified the selection project resin as well as the enhancement chemical additive performance, provides the precise electrical conductivity for yours application. Conductive plastic usually through superficial electronic resistivity (SR) the survey carries on the appraisal, the unit is ohms/sq. The electronic resistivity value is lower, the material more has the electrical conductivity. Usually the material classification follows: produces 109 the friction electric discharge which to 1012 ohms/sq performance range's anti-static electricity plastic are least, and may prevent the static discharge and the human body contact. can prevent the static discharge and the human body contact 106 to 109 ohms/sq scope's dispersive plastic. can disperse the friction electric discharge 102 to 105 ohms/sq scope's conductive plastic. may use in 100 to 102 scope's EMI.RFI shield plastics absorbing and the reflection electromagnetism and the radio-frequency interference. Stat-Tech formula's other superiority and the characteristic basis use the enhancement chemical additive is different and is different, these chemical additives including powdered carbon, carbon fiber, nickel coating carbon fiber and stainless steel textile fiber and so on. May use each kind of substrate resin to become the Stat-Tech compound.
