K5 FORM SELECTION

K5 tapioca CMS powder and flake selection guide

K5 is KARN standard tapioca CMS with DS 0.3 and is available in powder and flake form for textile printing evaluation This guide separates the public flake method data from powder details that must remain controlled until the current TDS and a representative sample are reviewed

Reviewed by KARN Textile Chemicals product team Published July 2026

What does this K5 guide confirm

K5 identifies the standard tapioca CMS grade in the verified KARN textile range Both powder and flake can be requested The published flake result is nominal viscosity 24000 mPa s with a confirmed range from 21600 to 26400 mPa s when the same 5 percent solution NDJ 8 spindle number 4 and 6 r min method is used

When to request K5 powder information

K5 powder is available but the public flake viscosity range does not define its powder specification Confirm the required powder characteristics packing and process fit through the current KARN TDS and a sample before setting a production requirement

When the K5 flake range can be compared

Compare a K5 flake result only after matching the material form solution concentration instrument spindle and rotational speed to the published method A number outside that controlled context is not a comparable K5 result

What to include in a K5 evaluation request

  • Textile printing process
  • Fabric and recipe context
  • Required powder or flake form
  • Target viscosity or test conditions
  • Sample or batch reference when available

What still needs current TDS confirmation

K5 pH solubility powder specifications packing and grade specific process suitability are not confirmed by this guide Request the current KARN TDS and evaluate a representative sample before a production decision

Review the K5 product page Check the flake viscosity method Prepare a sample and TDS request Request current K5 documentation
