High Purity and Stability for Chemical Processes
We offer dry lime powder chemical. This product reflects our pursuit of "high purity" and "high stability." We use high-grade limestone as the raw material. It is processed through high-temperature calcination, precise hydration, purification, classification, and grinding.
Our factory is certified with ISO9001, ISO14001, and ISO45001. We have a complete quality management system. We are not just a supplier-we are a trusted expert in calcium hydroxide. Our dry lime powder chemical is a stable and high-purity product.
Key Specifications and Superior Quality
We maintain strict quality control throughout the entire process, ensuring stable chemical composition and excellent physical properties. The table below shows our high-purity product range.
●CH-95-200 is a high-purity economic grade for high-standard environmental protection and general chemical synthesis.
●CH-95-250 is a balanced grade combining purity and reaction rate.
●CH-95-325 is an ultra-fine, high-purity grade for precise reactions and high-end applications.
●CH-96-FOOD is a food-grade hydrated lime that meets food additive standards for food and pharmaceutical applications.
Our dry lime powder chemical is designed for demanding chemical processes.
