Stearic acid amide

​Stearic acid amide (Stearamide) can be used as sensitizer & slip additive in thermal paper coatings as well as slip and antiblock additive in polyolefin films.

Stearmide is based on fatty saturated straight chain monocarboxylic acid derived from naturally occurring vegetable oils.

Thermal Paper

Stearamide was one of the first sensitizers used in thermal paper. Nowadays its low cost makes it attractive as a supplementary sensitizer, i.e. used in combination with other sensitizer.

Available in 2 different types:

  • S70 = C-18 content min. 70%
  • S90 = C-18 content min. 90%

Polyolefin Films

Stearamide slip additives effectively reduce co-efficient of friction on film surface and are used as slip, antiblock and mould release agents. These additives are suitable for PP, PE and EVA.
