Powdered sulphur
S
Powdered sulphur is made by grinding solid sulphur. Particle fineness, expressed as mesh, is the main difference between grades and decides what the powder can be used for.
Also known as: Sulphur powder, ground sulphur

Sourcing and our role
Mercopars is the direct sales representative of several powdered-sulphur producers. We work directly with producers in this segment and also supply raw material to many of them.
Form and grades
Grades are distinguished by mesh and sometimes by anti-caking or dispersing additives. State the mesh and type you need in the enquiry.

Technical data sheet (PDF)TDS-PS-01What to check before buying
- Sulphur purity
- Mesh and percentage passing the sieve
- Moisture
- Ash
- Acidity
- Presence and type of additives
These figures depend on grade, producer and lot. They are read from the certificate of analysis of the lot offered, not from this page.
Uses
- Agriculture: soil amendment and sulphur nutrition
- Rubber industry: vulcanisation, in the grade and fineness that industry specifies
- Chemical industry and sulphur compounds
Specifications and delivery
Grade, packaging, quantity and delivery terms are confirmed against the producer’s analysis and your enquiry.
Questions buyers ask
Why does mesh matter for powdered sulphur?
Finer particles have more surface and react faster, but they also create more dust and stricter handling and storage requirements. Agricultural and rubber uses call for different fineness, so choose the mesh by end use.
