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 application fields.
Latro has a wide range of linear polydimethylsiloxane polymers with kinematic viscosities of 50, 100, 200, 350, 500, 1,000 10,000 and 60,000 cSt.
Low molecular weight PDMS polymers, with viscosities less than 1000 cSt, are used extensively by the plastics industry as external release agents applied on the mold surface prior to injection molding. To eliminate an external application during processing, higher molecular weight PDMS oils, with viscosities ranging from 10,000 cSt to 60,000 cSt, are being used as internal additives in thermoplastic polymers to give processing advantages and surface property improvements.
PDMS oils are used in several industrial and consumer applications as heat and mechanical transfer fluid, hydraulic fluid, electrical insulating fluid, water repellent, polish ingredient, mold release agent etc.
