Manufacturing Quality Control of Polymethylhydrosiloxane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Viscosity | Capillary Viscometry | Measures flow time of sample through calibrated capillary tube under gravity to determine kinematic viscosity. |
| Acid Value | Acid-Base Titration | Quantifies free carboxylic acid groups by titration with standardized KOH solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetic Anhydride Acylation Titration | Determines hydroxyl content via acylation with acetic anhydride, followed by back-titration of unreacted anhydride. |
| Refractive Index | Refractometry | Measures bending of light as it passes through the sample at specified temperature to assess purity and composition. |
| Flash Point | Cleveland Open Cup (COC) | Determines lowest temperature at which vapors ignite momentarily when exposed to flame under standardized conditions. |
| Water Content | Karl Fischer Titration | Electrochemically quantifies water based on iodine-sulfur dioxide reaction stoichiometry in anhydrous methanol medium. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Measures mass loss upon controlled heating to quantify low-boiling impurities and residual solvents. |
| Appearance | Visual Inspection | Assesses clarity, color, and presence of particulates or phase separation against standard reference under controlled lighting. |
| Density | Pycnometry | Determines mass per unit volume using a calibrated glass pycnometer filled with sample at specified temperature. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing of sample in platinum crucible. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Cr) by plasma-induced atomic emission spectroscopy. |
| pH (10% aqueous dispersion) | pH Meter Measurement | Measures hydrogen ion activity in standardized aqueous dispersion using calibrated pH electrode and buffer references. |
