Silicone fluids and reactive silicone bases for polymer processing u2014 PDMS release-and-lubrication fluid, vinyl-terminated PDMS, and two-part liquid silicone rubber for molding.
Silicone processing aids are polydimethylsiloxane (PDMS) fluids and silicone elastomer systems used in plastics and polymer manufacturing to reduce friction during melt processing, improve surface finish and release, and mold flexible silicone components. Added at low loadings or supplied as a masterbatch, dimethicone-type fluids function as internal and external lubricants, slip agents, and mold-release additives that help reduce melt fracture and die build-up in thermoplastic extrusion and injection molding, while two-part silicone systems cure into finished elastomer parts. RawSource sources these silicone processing chemistries in bulk — drums, totes, and container loads — to buyer specification, matching viscosity, phenyl content, and cure system to the process.
For melt-processing and surface effects, Silicone Oil 5 cSt (Dimethicone, PDMS) is a low-viscosity fluid suited to slip, lubrication, and mold-release roles in thermoplastics, while higher-viscosity Polydimethylsiloxane (PDMS) Fluid grades are typically chosen where more persistent lubrication or masterbatch dispersion is needed. Phenyl Trimethicone, a phenyl-modified silicone fluid, typically offers a higher refractive index and greater thermal stability for formulations that call for those properties. For molding silicone elastomer parts, Liquid Silicone Rubber (LSR) is a two-part, addition-cure system for injection molding, built on Vinyl-Terminated Polydimethylsiloxane (Vinyl PDMS) as the reactive base polymer; high-consistency Silicone Rubber suits compression molding and extrusion of cured silicone goods.
