K - STOFF O is primary amides specially developed as mold release & slip additives for rubber application. In rubber application, these amide waxes also act as a processing aid and/or additive to improve the surface properties of both natural and synthetic rubbers such as NR, NBR, SBR, EPDM, CR, etc.

Functions: Mold Release Agent, Processing Aid, Release Agent, Slip Agent

Chemical Family: Amides

Compatible Polymers & Resins: Chloroprene Rubber (CR), Ethylene Propylene Diene Monomer (EPDM), Ethylene Vinyl Acetate (EVA), Natural Rubbers (NR), Nitrile Butadiene Rubber (NBR), Polyolefins, Styrene Butadiene Rubber (SBR)

End Uses: Automotive Components, Belts & Belt Repair, Film, Food Packaging, Footwear, Hoses

Product Background

Slip additives have been used in polyolefins for over 50 years to reduce the friction of films, mold release, facilitate the application, and removal of closures. Many materials have been proposed and used but monounsaturated fatty acid amides have become the standard for high slip applications. The most commonly used additives today are Oleamide and Erucamide which are monounsaturated primary amide with a carbon chain length of 18 and 22 respectively. These materials are highly effective slip agents, at modest addition levels have acceptable stability and volatility for most polyolefin processing.

Features & Benefits
  • K STOFF O (Oleamide) is a high purity fast blooming oleamide, suggested as a slip additive in polyolefin application. It reduces COF between the layer of the film and also between the film and other surfaces which are in contact with the film. Very small use level of 0.1 % K STOFF O will impart required slip properties to polyolefin films used for high speed packaging application
  • K STOFF O is the series of slip additives (Primary Amides) derived from natural resources
  • The main function of films, it reduces the COF between Polymer: Polymer or Polymer: Metal surfaces
  • In molding, it acts as an excellent mold release agent
