Lump Sulfur, purity of 99.50%.

$90 - $120 / Metric Ton (FOB)
MOQ: Not Specified
Supplier From Kota Bharu, Kelantan, Malaysia
 
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.

MALAYSIA ORIGIN SULFUR.

Please Note: Price fluctuates, as such price on page is base price and is subject to change

1 - Micronized Sulfur Powder
2 - Granular Sulfur
3 - Sulfur Coated Urea
4 - 4: Sulfur Bentonite

Supplemental Information:

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.

Spcification of Sulfur:

Color: Bright yellow when solid (No dark particles visible)
Purity: 99.8% by weight minimum, dry basis. Sulfur Content: 10ppm by weight, maximum (0.01%)
Moisture Content: 0.50% by weight maximum
Ash: 300ppm by weight, maximum (0.03%)
Organic matter: 500ppm by weight, maximum (0.05%)
Size: 2mm â?? 6mm
Bulk Density: Minimum 1040 Kg/m3 (loose)
Bulk Density: Minimum 1200 Kh/m3 (packed)
Acidity as H2SO4: 50ppm by weight, maximum (0.005%)
