Product Overview
Physicochemical Properties
Hydroxyl Value: 28~56 mg KOH/g (corresponding to molecular weight 2000~4000)
Viscosity (25ºC): 500~5000 mPa·s (higher molecular weight results in higher viscosity)
Glass Transition Temperature (Tg): -70~-55ºC (depends on microstructure; higher 1,2-structure content leads to higher Tg)
Solubility: Soluble in organic solvents such as toluene, acetone, and chloroform; insoluble in water.
Reactivit: Hydroxyl groups can react with isocyanates (-NCO), acid anhydrides, and epoxides, making it a key raw material for polyurethane synthesis.

VIew moreLooking for premium Liquid Mercury Hg? As leading China suppliers and a certified factory, we provide 99.999 purity mercury for gold extraction, thermometers, and sphygmomanometers with full export compliance.
Product Description
Mercury, chemically known as mercury (Hg), is the only metal that exists in liquid form at normal temperature and pressure. It has a silvery-white metallic luster, is highly fluid and has an extremely high density (13.59 g/cm³). Its unique physical and chemical properties, such as a low melting point (-38.87℃), high boiling point (356.6℃), stable coefficient of thermal expansion, and extremely low vapor pressure, make it a core material for many special products.

VIew moreSodium cyanide is a white crystalline powder at normal temperature and pressure. It is highly soluble in water, and its aqueous solution is strongly alkaline.
Sodium cyanide is an important chemical raw material, mainly applied in the following fields:
Electroplating industry: It is used for electroplating and surface treatment of metals, which can enhance the smoothness and adhesion of the coating.
Metallurgical industry: It is used for extracting precious metals such as gold and silver. By taking advantage of the property that cyanide ions form stable complexes with precious metal ions, it achieves the enrichment and separation of precious metals.
Organic synthesis: As an intermediate, it is used in the manufacture of drugs, dyes, pesticides and other chemicals.
APPLICATION
It is widely used for Gold, Silver extraction. It is a main part of plating liquids for zinc,copper, gold, silver, cadmium etc. It also used as the raw material for fine chemicals, pharmaceutical intermediates, pesticide intermediates, etc.
