New Impact Modifier For Polyamide Compounds and Direct Injection Mounding

SK Functional Polymer (SKFP) introduces Lotader? 4700T, a new impact modifier for polyamides. Lotader? 4700T is a highly reactive ethylene/ethyl acrylate/maleic anhydride terpolymer specifically designed for high impact resistance polyamide compounds.

The introduction of Lotader? 4700T comes as an extension of SK Functional Polymer range of tubular Lotader? terpolymers. It has the same composition as Lotader? 4700, but benefits from the tubular synthesis process. This brings a higher melting temperature and an improved dispersion into polyamides. Lotader? 4700T has been successfully tested in several polyamides such as PA6 and PA6.6. It brings high toughness while maintaining good compounds fluidity. This enables injection moulding of complex shapes.

It is also helpful in improving the performance of recycled polyamides for use in automotive applications. SKFP research group showed that Lotader? 4700T can perform even when used directly in injection moulding for medium toughness PA formulations. The direct injection of dry-blend polyamide and Lotader? 4700 additive enables to produce economically injection moulded parts.
