SK Functional Polymer (SKFP) introduces Lotader® 4700T, a reactive plastic additive for polyamides and ABS paintability.
Lotader® 4700T is a highly reactive 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 molding of complex shapes. It is also helpful in improving the performance of recycled polyamides for use in automotive applications. The direct injection of dry-blend polyamide and Lotader® 4700T additive enables to produce economically injection molded part with medium toughness.
Lotader® 4700T has also been successfully commercialized as additive in paintable ABS and PET straps.
