Product Introduction

Cyanuric acid (CYA), in the form of white crystalline powder, is a chemical compound commonly used in swimming pools. The form of powders is ideal for applications requiring rapid dissolution and uniform distribution in the water. Cyanuric acid is well-known for its ability to stabilize chlorine, thereby extending its effectiveness in the process of disinfecting and sanitizing water.

Applications
1. Swimming Pool Maintenance The main application of cyanuric acid powder is in swimming pool maintenance, where it acts as a stabilizer for chlorine. When added to the pool, it forms a complex with free chlorine, preventing it from breaking down rapidly under sunlight. This extends the effective life of chlorine in the pool water, reducing the frequency of chlorine addition and maintaining a consistent level of disinfection.
2. Water Treatment In addition to swimming pools, cyanuric acid powder is also used in various water treatment processes. Its ability to stabilize chlorine makes it valuable in drinking water systems, wastewater treatment plants, and other industrial water processes where consistent chlorine levels are crucial for disinfection and safety.
3. Industrial and Agricultural Fields Cyanuric acid is also utilized in industrial and agricultural fields. It is employed as a raw material for production of fungicide, herbicide, and algicide, contributing to crop protection and improved agricultural yields.
4. Chemical Intermediary Due to its excellent chemical stability, cyanuric acid powder is often used as an intermediate in the production of other chemicals. It can be chlorinated to form chlorinated isocyanurates, which are widely used as sanitizers and disinfectants in various applications. Besides, cyanuric acid used to produce chlorinated isocyanurates has strict requirements for nitrogen content.
Advantages
⚡ Rapid Dissolution The fine powder form allows for quick and complete dissolution in the water, ensuring immediate effectiveness.
🔄 Uniform Distribution When added to water, the powder disperses evenly, providing consistent chlorine stabilization throughout the pool or water system.
✅ High Purity With a minimum purity of 99%, cyanuric acid powder offers superior performance and minimal contamination.
🔧 Versatile Use Suitable for a wide range of water treatment systems, from small residential pools to large commercial facilities.
Features
Effective Chlorine Stabilization: Cyanuric acid powder effectively prevents chlorine degradation due to sunlight, reducing the frequency of chlorine additions.
Fine Particle Size: The fine particle size of powder enhances its solubility and ensures a uniform mixture in water.
Eco-Friendly: This product is non-toxic and environmentally friendly, making it a safe choice for pool maintenance and other applications.
Storage

Frequently Asked Questions
Q What is cyanuric acid (CYA) and what is it used for?
Cyanuric acid (CYA), also known as isocyanuric acid, is a white crystalline powder primarily used as a chlorine stabilizer in swimming pools. It is also used in water treatment, industrial processes, agricultural applications (as a raw material for fungicides, herbicides, and algicides), and as a chemical intermediate in the production of chlorinated isocyanurates.
Q How does cyanuric acid stabilize chlorine in swimming pools?
When added to pool water, cyanuric acid forms a chemical complex with free chlorine. This bond protects chlorine molecules from being rapidly broken down by ultraviolet (UV) rays from sunlight. As a result, chlorine remains active in the water for a longer period, reducing the need for frequent re-dosing and helping maintain consistent disinfection levels.
Q What is the recommended storage method for cyanuric acid powder?
Cyanuric acid powder should be stored in a cool, dry location away from direct sunlight and moisture. It must be kept in tightly sealed containers — preferably HDPE or PP — to prevent contamination and degradation. It should also be stored away from strong oxidizing agents and other incompatible chemical substances.
Q What purity level does your cyanuric acid powder offer?
Our cyanuric acid powder offers a minimum purity of 99%, ensuring superior performance, minimal contamination, and consistent results in all applications — from swimming pool maintenance to industrial chemical production.
Q What packaging options are available for cyanuric acid powder?
Cyanuric acid powder is available in multiple packaging formats to suit different needs: 25 kg bags, 1000 kg big bags, 50 kg drums, 50 lbs drums, and 100 lbs drums. All packaging is made from high-density polyethylene (HDPE) or polypropylene (PP) for maximum durability and protection during transport and storage.
Q Is cyanuric acid powder safe for the environment?
Yes, cyanuric acid powder is considered non-toxic and environmentally friendly when used as directed. It is a safe choice for swimming pool maintenance and other water treatment applications. However, it should always be handled and stored properly, following safety guidelines to avoid any unintended environmental impact.
