Atmer™ 7300

Technical Datasheet | Supplied by Croda
Atmer™ 7300 by Croda is 50% concentrate in polyethylene of non-vegetable origin. Acts as a specialty release concentrate. It is recommended for use in EPE to improve the cell size distribution and foaming gas / air exchange. It is a combination of additives dispersed in an adsorbent polymer. Using a concentrate allows for better dispersion and overcomes complications encountered when using additives in their normal physical forms. Concentrates are added to the process like other resins, allowing for the additives to migrate to the surface where the additive interacts with atmospheric moisture reducing resistivity and dissipating static charge. It allows for better distribution of additives in the base polymer, easier processing and reduced manufacturing noise and improvements to cell size distribution. It can be incorporated into resin as supplied or via masterbatch / pre-blend. Experience has shown that simple manual mixing prior to processing will normally give an acceptable dispersion though, mechanical means are preferred. Typical addition levels of Atmer™ 7300 is 2-3%. It has a shelf life of 730 days. It is approved for food contact.
