NOF®-ALLOY KA Series

NOF®-ALLOY KA series, functional polymer additives, can resist scratch, wear, and squeak noise.

NOF®-ALLOY KA series is one of the scratch resistance improvers developed by NOF’s graft technology expertise and experience. NOF®-ALLOY KA serieseries has the following three excellent features.

  • NOF®-ALLOY KA Series can improve the scratch resistance of polyolefin, PC/ABS,PC, ASA, PMMA. thermoplastic olefin elastomers (TPO) and cross-linked rubber.
  • NOF®-ALLOY KA Series can keep the appearance of surface, mechanical properties, thermal properties, and mold ability.
  • NOF®-ALLOY KA Series is friendly for the environment so that no halogenic compounds are contained

NOF®-ALLOY KA Series can be used for many polymer applications such as cars, electronic devices, and furniture which have to be prevented from scratch, wear, or squeak noise. Especially, NOF®-ALLOY KA Series is suitable for applications made from polypropylene.

NOF®-ALLOY KA is suitable for polymers have to be prevented from scratch, wear, and squeak noise.


Features of NOF®-ALLOY KA series

How to use

Before molding, you can add 1~5w% NOF®-ALLOY KA with the same method as color master pellet. Also, you can get better anti-ware property polymers with compounding.
