SUNOIT™Silicone Additives for Sulfur Granulation: Safe, Efficient Forming & Dust Control

Sulfur granulation is a critical refining process that converts molten sulfur into easy-to-handle solid hemispherical pellets. Molten sulfur is toxic, corrosive, and readily reacts with moisture to form sulfuric acid, posing significant storage and handling hazards. Solidifying it into uniform granules enhances safety and simplifies transportation and storage. In this process, silicone additives serve as essential forming and release agents applied on steel belt conveyors.

SUNOIT has developed a dedicated series of silicone additives tailored to the demands of sulfur granulation. The product is applied to the steel belt surface and delivers dual functionality: as a forming agent, it helps shape molten sulfur into uniform, well-defined hemispherical pellets, improving product appearance and consistency; as a release agent, it forms an ultra-thin separating film between the sulfur pellets and the steel belt, ensuring clean, effortless separation after solidification without sticking or residue.

The unique Si-O-Si backbone of silicone molecules imparts extremely low surface tension and excellent chemical inertness. This ensures stability upon contact with high-temperature molten sulfur, with no decomposition or migration. The isolating film also effectively suppresses dust generation caused by friction during pellet release and conveying, significantly reducing dust levels in the granulation workshop, improving the working environment, and lowering dust explosion risks.

SUNOIT silicone additive products are available in both solvent-based and water-based emulsion forms, and can be flexibly customized according to belt material, granulation speed, and process temperature. Low-VOC, safe, and environmentally friendly, our products deliver consistent quality and rapid response, providing sulfur granulation enterprises with compliant, high-efficiency, one-stop additive solutions that enable safe, clean, and high-quality continuous production.
