シリコーン系加工助剤

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.

溶融加工および表面効果のためには、 シリコーンオイル 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, 液体 シリコーンゴム (LSR) は射出成形向けの2液型付加硬化システムで、ベースポリマーは Vinyl-Terminated Polydimethylsiloxane (Vinyl PDMS) を反応性ベースポリマーとして用います。ミラブル型シリコーンゴム (HCR) は、硬化シリコーン成形品の圧縮成形および押出成形に適しています。
