IRGASTAT P Antistatic Additives
IRGASTAT P Antistatic Additives
Irgastat P are polymeric systems based on polyamide/polyether block amides.
Irgastat P is recommended, where a permanent antistatic effect is sought, in applications such as electronic and industrial packaging, housings and parts of business machines. Products can be used in thermoplastic polymers, transparent film, fiber or molded applications. Outdoor applications require testing to determine the suitability of Irgastat P under UV-exposure conditions.
Irgastat P products are polymeric materials incorporated as melt additive. Electric resistivity is reduced by formation of a conductive percolating network. Irgastat P 18 FCA and P 22 is forming a more distinct fiber network as opposed to Irgastat P 16 and P20 thus requiring lower addition levels.
