Anti-Stats, Conductive & Static Dissipative Masterbatch & Compounds
Every year there are many millions of dollars of losses due to static discharges. While lightning may be the most visible reminder, it only takes a small static discharge to damage electrical components, magnetic media or start a fire. As computer components and circuits become smaller, the amount of static that will damage those components drops proportionately.
Conductivity and resistivity are measured in ohms/square.
Plastics are considered conductive when they measure 10*1 to 10*6 ohms/square. Metals measure 0 to 10*-3. These materials discharge instantaneously.
Plastics are considered dissipative when they measure between 10*6 and 10*10 ohms per square. This range is similar to resistors in electronics that slow down the flow of electricity and allow quicker discharge than anti-stats.
Anti-static polymers measure 10*10 to 10*12 and provide a slow decay of static charge.
The 3 basic systems that Peacock supplies are:
▪ Conductive carbon or metals for polymers and coatings
▪ Inherently Dissipative Polymers “IDPs,”
▪ A traditional line of chemical anti-stats.
Selection and formulations determined by balancing the rate of dissipation with economics and aesthetics.
