Polydimethylsiloxane Oils

Silicones in the industry usually refer to linear polydimethylsiloxanes (PDMS). A combination of properties such as their backbone flexibility, low intermolecular interactions, low surface tension, and thermal stability explains many of their applications.

Silicones differ from organic compounds in both their physical and chemical properties;

  • High and low temperature stability
  • Oxidative stability
  • Chemically inert
  • Low flammability
  • Low surface tension
  • Shear stability
  • High compressibility
  • Low vapor pressure
  • Low odor
  • Non-oily feel
  • Spreadability
  • Low coefficient of friction
  • Lubricious

Latro Kimya has a different range of linear polydimethylsiloxane polymers with kinematic viscosities of 50, 100, 200, 350, 500 and 1000 cSt.

In the textile industry, polydimethylsiloxanes are used in all stages of the process, applied on the fiber during production and/or directly on the finished good. The silicone oil is applied by different delivery systems to provide various benefits like lubrication, softening, foam control or hydrophobic coatings.

Higher production rates oblige artificial fiber producers to continuously search for more efficient materials to lubricate fiber and spinneret and to avoid excessive overheating due to friction during high-speed manufacturing. Silicones can also be used to achieve low coefficients of friction between the fibers themselves. During the manufacturing of artificial fibers, PDMS can also be used as a lubricant to avoid adhesion of the thermoplastic fiber material to the spinneret, which would cause an unstable production and cleaning issues.
