High Purity and High Activity for Premium Applications
We offer lime hydrated powder. This product reflects our pursuit of "high purity" and "high activity." We use high-grade limestone as the raw material. It is processed through high-temperature calcination, precise hydration, purification, classification, and fine grinding.
Our factory operates 6 automated production lines with an annual capacity of 300,000 tons. Our R&D team includes 9 senior engineers focused on improving product purity and activity. We are not just a supplier-we are a trusted expert in calcium hydroxide. Our lime hydrated powder is a premium-grade 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.
We offer several grades:
●CH-95-200 is a high-purity economic grade for high-standard environmental protection and general chemical synthesis.
●CH-95-250 is a balanced high-purity grade suitable for fine chemical applications with optimized cost performance.
●CH-95-325 is an ultra-fine high-purity grade for food, pharmaceutical, and electronic applications.
●CH-96-FOOD is a food additive grade that complies with GB 1886.214 for food and pharmaceutical use.
Our lime hydrated powder is designed for demanding applications.
