Grades & Performance Range:Grades & Performance Range:


Non Permanent Chemical Non Permanent Chemical AntistatAntistatMode of Action:

� Low molecular weight chemical species with a non-polar chain and a polar hydrophilic head

� Migrate to the surface of the material, attracts water which lowers RS and allows to dissipate static charges:

BUT:

� Need ambient humidity to be efficient: No effect in dry conditions.

� Need time to migrate and bring antistatic properties: No immediate effect.

� With time additives are wiped away from the surface of the material: No Permanent effect, Static charges will reappear.

Principle of Principle of PebaxPebax ®® Permanent AntistaticPermanent Antistatic� Addition of Pebax® to the Polymer matrix by dry blend, both polymers are mixed during processing,

Example of PEBAX MV 1074 conductive network in PS matrix

Antistatic Pebax® domains forms a Permanent 3D ionic dissipative network within the matrix which allows to dissipate charges along Pebax backbone.

PebaxPebax®® Antistatic PropertiesAntistatic Properties


� Antistatic Pebax® forms a polymer network in the matrix, it doesn’t migrate nor bring any blooming

� Pebax® antistatic effect is immediate and permanent.

� Chemical antistatic agents are very sensitive to relative humidity and are inefficient in dry conditions

� Pebax® antistatic effect is maintained even at low humidity level.
