Sulfur Products & Solutions

Product overview

Sulfur is an important raw material used in agricultural fertilizers and various industrial applications. Alzak offers six sulfur-related products in different physical forms and compositions: elemental sulfur granules, sulfur-coated urea, sulfur bentonite, micronized sulfur powder, sulfur pastilles, and lump sulfur. Each product has its own technical specifications, physical characteristics, and applications.

Bright-yellow granular sulfur
01

Granular Sulfur

99.95% minimum purity

Granular Sulfur (S) is a high-purity elemental sulfur product supplied in hard, bright-yellow granules. It is a source of the essential nutrient sulfur, supporting protein synthesis, oil content, and nutrient uptake, and helps lower soil pH in alkaline soils. It is also used in the manufacture of sulfuric acid and fertilizer blends.

Sulfur Coated Urea (SCU)

36% N | 15% S

Sulfur Coated Urea (SCU) is a granular urea fertilizer coated with a layer of elemental sulfur. The coating slows the release of nitrogen, reducing losses and extending feeding time, while also supplying sulfur to the crop.

03

Sulfur Bentonite

85–91% sulfur content

Sulfur Bentonite combines elemental sulfur with bentonite clay in a pastille (half-sphere) form. On contact with soil moisture, the bentonite swells and breaks the pastilles into fine particles, allowing sulfur to be oxidized into plant-available sulfate for crops and for lowering soil pH.

Micronized Sulfur Powder

99.8% minimum purity

Micronized Sulfur Powder (S) is a fine, light-yellow elemental sulfur product milled to the mesh grade required by the customer. Its fine particle size gives fast dispersion and reactivity, making it widely used in agriculture, rubber vulcanization, and chemical manufacturing.

Storage & handling

Store away from heat, sparks and ignition sources. Protect from moisture and dust. Keep sealed in a well-ventilated area and avoid contact with acids and alkalis.

H₂S precaution

The supplied technical data sheets identify traces of hydrogen sulfide (H₂S) in Granular Sulfur, Sulfur Bentonite, Micronized Sulfur Powder, Sulfur Pastilles, and Lump Sulfur. Avoid dust generation when handling these products.
