Application
Sulfur alias sulfur, colloidal sulfur, sulfur block. The appearance is light yellow brittle crystal or powder, with special odor. The molecular weight is 32.06, the vapor pressure is 0.13kPa, the flash point is 207â??, the melting point is 119â??, the boiling point is 444.6â??, and the relative density (water =1) is 2.0. Sulfur is insoluble in water, slightly soluble in ethanol, ether, easily soluble in carbon disulfide. As a flammable solid, sulfur is mainly used in the manufacture of dyes, pesticides, matches, gunpowder, rubber, rayon and so on.
Sulfur is an important variety of inorganic pesticides. The product is yellow solid or powder, with obvious odor and can be volatilized. Sulfur water suspension is slightly acidic, insoluble in water, and reacts with alkali to form polysulfide. Sulfur burns with a cyan flame and produces sulfur dioxide gas. In production, sulfur is often processed into colloidal suspension for the prevention and control of pests and diseases, which is safe for people and animals and is not easy to cause drug damage to crops.

Sulfur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S. Elemental sulfur is a bright yellow, crystalline solid at room temperature.

Lump sulfur, also known as granular or rock sulfur, is typically characterized by a purity of 99.80% or higher, with a maximum ash content of 0.05%.
It should also have a limited acidity (H2SO4) of 0.02% or 0.03% and minimal moisture content (0.5% or 0.2%).
More detailed breakdown of lump sulfur specifications:
Purity:
Dry Basis: 99.80% minimum purity is a common specification.
Other Standards: Some standards like Refinery Specifications, may specify a purity of 99.98%.
Impurities:
Ash Content: A maximum ash content of 0.05% is a typical requirement.
Acidity: A maximum acidity (H2SO4) of 0.02% or 0.03% is common.
Organic Substances: Some specifications limit organic substances to 0.01% or 0.03% maximum.
Moisture: A maximum moisture content of 0.5% or 0.2% is generally specified.
Mechanical Impurities: Some specifications require the absence of mechanical impurities like paper, wood, or sand.
Other Impurities: Some standards specify limits for arsenic, selenium, tellurium, and lead impurities.
Color and Appearance:
Color: Bright yellow is the typical color specification.
Other Considerations:
Test Methods:
Specifications often include test methods, such as ASTM D-4239, ASTM D-1509, ASTM D-1613, and ASTM D-2790, for determining the various parameters.
Bulk Density:
Granular sulfur has a bulk density of around 70 lb/cu ft (1121.29 kg/cu m).
Solubility:
Sulfur is insoluble in water, partially soluble in acetone, and slightly soluble in diethyl ether and alcohol.
Keep away from heat, hot surfaces, Sparks, Open flames and other ignition sources. No smoking. Proper
grounding procedures to avoid static electricity should be followed. Prevent dust accumulation (to minimize
explosion hazard). Avoid generating dust.
Other Hazards:
It contains a small amount of Hydrogen Sulfide. Hydrogen sulfide is a fatal and highly flammable gas with a
rotten egg odor that quickly causes odor fatigue. Heating of this product and storage under elevated
temperatures or over long periods of time may release higher amounts of Hydrogen Sulfide. Hydrogen
Sulfide is also an asphyxiant. Exposure may aggravate preâ??existing eye, skin, or respiratory conditions.
Storage:
(1) Prevent from moisture absorption, keep away from heat, keep in air well â?? ventilated area.
(2) Do not contact with acids and alkaline substance, protect from dust.
(3) Ensure bags are kept in sealed and in good condition.
Packing:
The packing is in 50/Kg. bags, Jumbo Bag 1/MT or in Bulk.
