Functional Additives for Polymer Electronics

So far the retention or stabilisation of polymer characteristics has been discussed. The last part is functional additives in polymer electronics. In electronics applications, polymer tends to have contact with metals because metals are used as conductors, solder, springs, screws and other small parts. If the polymer is in contact with metals, especially transition metals, the degradation of polymer is accelerated. In that case, metal deactivation provides the solution. 

Standard application of metal deactivator is jacketing of the cable because it contacts to copper wire. Copper ions can accelerate the degradation by changing valance. 

Metal deactivators form stable complexes with metal ions 

Electricity induces static charge. This causese dust pick up, which interferes with the calrity, handling problems and electrical discharges which may induce electrical shocks for fire or dust explosion. Antistatic agents can solkve such an issue. 

The last topic is halogen free flame retardants. Needless to say, the benefit of flame retardancy is to minimise the risk of Are accidents. Melamine derivatives are a niche in the flame retardant market, but have significant advantages in specific polymers.
