Polyacrylamide

We offer the following Specifications：

Molecular weight: Polyacrylamide can have a wide range of molecular weights, ranging from thousands to millions of Dal-tons. Higher molecular weight polyacrylamides are typically more viscous and have better flocculating properties.

Charge density: Polyacrylamide can be either nonionic, anionic, cationic, or amphoteric, depending on the type of functional groups present on the polymer chain. The charge density of polyacrylamide can affect its interactions with other molecules and its ability to flocculate suspended particles.

Solubility: Polyacrylamide is generally soluble in water and forms viscous solutions. The solubility of polyacrylamide can be influenced by factors such as pH, temperature, and ionic strength.

Density: The density of polyacrylamide can vary depending on its chemical composition and molecular weight. Generally, polyacrylamide has a lower density than water.

Rheological properties: Polyacrylamide solutions exhibit shear-thinning behavior, meaning that they become less viscous under high shear rates. This property makes polyacrylamide solutions effective as thickening agents in various applications.

Thermal stability: Polyacrylamide is typically stable at high temperatures, making it suitable for use in industrial processes that involve elevated temperatures.

Compatibility: Polyacrylamide is compatible with a wide range of substances, including other polymers, surfactants, and salts, making it versatile for various applications.

When handling PAM, appropriate personal protective equipment should be worn, such as chemical protective glasses, lab coats, and chemical protective gloves. At the same time, avoid direct skin contact with PAM powder or solution.

PAM becomes very slippery when combined with water, so use extra caution to prevent PAM powder from spilling or being oversprayed on the ground. If accidentally spilled or sprayed, it may cause the ground to become slippery and pose a hidden danger to personnel safety.

If your clothes or skin accidentally get PAM powder or solution, do not rinse directly with water. Gently wiping off PAM powder with a dry towel is the safest method.

Granular PAM should be stored in a light-proof container away from sunlight and air to maintain its effectiveness. Prolonged exposure to sunlight and air may cause the product to fail or even deteriorate.

If the product is found to be invalid or expired, it should be dealt with in time and replaced with a new product to avoid affecting normal use and safety.

At the same time, attention should be paid to checking the shelf life of the product and confirming its effectiveness before use through relevant tests or inspections to ensure that it meets standard requirements.
