New permanent antistatic additives for electronic packaging

A newly developed permanent antistatic additive from Techmer PM, USA, is used in LLDPE, HDPE, PP, HIPS and ABS medical nonwovens, soft and rigid electronic packaging. Tests on nylon 6, PBT and PET have also shown promise. Unlike conventional amino-based antistatic agents, the new Techsperse IDP is based on the attachment of a polyurethane segment to the alkyl chain, which is compatible with polyolefins. The surface resistivity of this environmentally friendly antistatic agent is 11Ω·m 2 , so the static electricity can be dissipated within a few minutes and a second.
