Frequently asked questions about Silbione DM 300 GMP
Practical application and design questions — answered by SILITECH.
Silbione DM 300 GMP: GMP-certified dimethicone (300 cSt) for pharmaceutical applications — highest purity, pharmaceutical excipient according to Ph. Eur. / USP. Main applications: pharmaceutical excipient, premium dermatological creams, anti-foaming pharmaceuticals.
PDMS (Polydimethylsiloxane) is a linear silicone fluid with high thermal stability, low surface tension, very good dielectric properties, and broad temperature resistance. The viscosity (in mm²/s = cSt) determines the field of application — low viscosities for volatile lubrication and hydraulics, high viscosities for antifoam, damping, and care conditioning.
Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
