Applications :

     ◾️   Anti-statics 9129 is an internal antistatic agent used in injection molding on a world-wide basis with wide food contact

           approvals and beneficial side effects.

     ◾️   Anti-statics 9129 is used as a process aid in production of expanded polyethylene (EPE) to im- prove the gas exchange

            (replacement of hydrocarbons -foaming gas- by air).

     ◾️   Anti-statics 9129 is recommended in the manufacturing of PP-caps to provide a slip/lubricant ef- fect, in addition to 

            the antistatic effect.

Mode of Action :

Internal antistatic agents act in two ways: building up a conductive path to bring charged particles into contact and as a lubricant or demolding agent in the post-extrusion process. An internal antistatic agent is incorporated into the polymer matrix during the extrusion pro- cess. Upon extrusion, the additive migrates to the surface of the polymer - because of its defined incompatibility with the polymer - where the additive builds up an uniform layer on the polymer’s surface. The hydrophilic end projects out of the polymer, the lipophilic end anchors in the polymer. The protruding hydrophilic end absorbs moisture from the sur- rounding air and builds up a conductive path, reducing the surface resistivity. (This also explains why mainly too high concentrations of antistatic agents will have an influence on printing and sealing properties and why antistatic agents are hygroscopic and have to be handled accordingly).

Features / Benefits :

     ◾️   Using Anti-statics 9129 as antistatic agent reduces dust contamination, affecting both appearance and performance of the end

             product. Handling problems during transport, storage and packaging are often reduced.

     ◾️   In injection molding Anti-statics 9129 reduces the cycle times by providing a mold release effect and improves the surface finishing.

     ◾️   In EPE Anti-statics 9129 reduces the friction during the extrusion process, giving an uniform cell size distribution and is improving

            the gas exchange (facilitating the diffusion of the foaming gas out of the cells and its replacement by air). By increasing the gas

            exchange rate be- tween the foaming gas and air, Anti-statics 9129 can significantly reduce storage time and cost.

     ◾️   Anti-statics 9129 improves the slip characteristics, e. g. of PP-caps, by reducing the forces needed to turn the PP-caps to open

            or close bottles.
