Fluidos de silicona y bases de silicona reactivas para el procesamiento de polímeros — fluido PDMS de desmoldeo y lubricación, PDMS vinil-terminado y caucho de silicona líquida bicomponente para moldeo.
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, Líquido Caucho de silicona (LSR) es un sistema bicomponente de curado por adición para moldeo por inyección, basado en Vinyl-Terminated Polydimethylsiloxane (Vinyl PDMS) como polímero base reactivo; el caucho de silicona de alta consistencia es adecuado para el moldeo por compresión y la extrusión de artículos de silicona curada.
