Q1. How to choice antistatic agent ?
A. Specification of Surface Resistivity
The test method of antistatic performance includes Surface Resistivity, Volume Resistivity and Decay Time. The specification of Surface Resistivity is about E9 ~E11 below in regular antistatic treated products.
Our standard type antistatic master batch can achieve to E9 ~E11 for your different request.
B. Specification of Relative Humidity
Antistatic performance of conventional antistatic agent will become very poor under low relative humidity. But the permanent type antistatic agent will not lose the antistatic performance even under 50% or less relative humidity.
Our permanent type antistatic master batch contain unique conductive polymer. The Surface Resistivity can achieve to E9 ~E11 and humidity independently.
C. Request of printability and welding processing
The over migration of conventional antistatic agent will influence printability and welding process. The poor surface properties come from poor compatibility between antistatic agent and polymer. For the protective film product, the oily migration contaminate the protected substance likes TFT-LCD.
Our permanent type antistatic master batch can be dispersed in the polymer uniformly and non-migration completely. The treated product will not decrease the printability and welding ability,
D. Request of washing resistant
Some electronic plant use recycle antistatic tray after washing. But the antistatic performance of conventional antistatic agent will become very poor after washing process.
Our permanent type antistatic master batch contain unique conductive polymer. The excellent antistatic performance is maintained after washing and wiping to submit most critical specification.
