Antistatic additives conduct at a new levelAntistatic additives conduct at a new level
Inherently dissipative polymers (IDPs) are widely used as permanent antistatic additives in a large range of polymer matrices in many different applications where they serve to prevent electrostatic discharge and dust attraction. The latest offerings from Arkema are said to take performance that extra ohm.

Nowadays, many applications such as packaging of sensitive electronic goods or critical industrial packaging for flammable or explosive goods, requires high static dissipative performance, while retaining the mechanical and optical properties of the host matrices. To answer these needs, Arkema has developed two new high-performance antistatic grades-Pebax MH2030 and Pebax MV2080-boasting higher conductivity compared to existing grades translating into two order of magnitude lower surface resistance that is in the range of 106 ohms/sq.
Through these improved antistatic properties, Arkema says processors are able attain higher performance by giving better static dissipative properties to their end products or realize similar antistatic properties with reduced additive loadings, consequently better preserving the properties of the host polymer matrix.
The new static dissipative Pebax grades retain all the key properties of existing antistatic Pebax grades MH1657 and MV1074, and performance is immediate, permanent, and stable over a large window of relative humidity. Grades MH2030 and MV2080 are selected depending on the matrix and the end application, MV2080 being particularly suitable for applications requiring a high cleanliness and very low outgassing.
All antistatic Pebax grades can be added directly by dry-blend for injection or extrusion in a wide range of matrices (PA, PP, PE, ABS, PC/ABS, PET, PS, TPU, PMMA, and PVC). Pebax is a polyether block amide resin. —Stephen Moore
