Focus Products for Plastics: The KF Range, Key Colour Shades and CICP Pigments

A round-up of Sudarshan's focus pigment portfolio for plastics — the filtration-friendly KF range for polyolefin film and fibre, a curated set of lemon and golden yellow, red, violet and blue shades for PO/PVC/PS/PP and PET fibre, and the Heucodur CICP inorganic pigment range from Germany for the toughest heat and weather-fastness needs.
KF Range

KF Range

Sudarshan's KF range is purpose-built for polyolefin (PO) film and fibre customers who need pigments that run cleanly through fine filtration.

Value to the customer:

  • High filtration performance — specially developed to meet a stringent FPV requirement of < 2 bar/g on a 10-micron mesh
  • Better processing stability — ensures excellent filtration behaviour and smooth, trouble-free extrusion
  • Reduced downtime — minimises the risk of screen choking and filter blockage during production
  • Improved productivity — enables improved processability and supports higher production efficiency
  • Reliable quality — supports consistent quality in film and fibre applications, with high cleanliness and excellent dispersion

Key advantages: low FPV (< 2 bar/g on 10µ mesh), excellent filtration behaviour, smooth processing, reduced filter blockage, and consistent surface appearance — designed for high performance, built for reliability, driven by efficiency, delivering consistent value.

Product Range

The KF series covers yellow, red, blue and green shades across PP, PET and PA fibre:
