Microcrystalline Cellulose

Appearance: White free-flowing crystalline fine powder, odorless, porous granular structure
Density: 1.5 g/cm³; Bulk density: 0.25–0.45 g/cm³
Solubility: Insoluble in water, ethanol, acetone and plasticizers (DOP/DOTP); swells upon water absorption, slightly swells in dilute alkali solution
Thermal Stability: Thermal decomposition temperature above 300℃; no decomposition or yellowing during PVC granulation at 160–180℃
Moisture Content: ≤5.0%; Ignition Residue: ≤0.1%

Main Grades: PH101 (fine powder, excellent dispersibility), PH102 (general standard grade), PH200 (ultra-fine, high adsorption capacity)

Characteristic Peaks: Strong hydroxyl absorption peak at 3200–3500 cm⁻¹, C-H peak at 2900 cm⁻¹, characteristic cellulose C-O-C peak at 1050–1160 cm⁻¹, serving as unique molecular fingerprint.
Main Uses:
Distinguish genuine products from counterfeits during incoming quality inspection, prevent adulteration with talc powder or calcium carbonate;
Mandatory supporting document for Russian clients, customs inspection and EAC registration;
Retain IR spectra for each batch for filing, to trace root causes of surface blooming and whitening defects.
