Description

1,2-Ethanediamine, Polymer With (Chloromethyl)Oxirane And α-Hydro-ω-Hydroxypoly( Oxy-1,2-Ethanediyl), Formate is a specialized cationic polymer, specifically a polyamine-epichlorohydrin adduct modified with a polyether chain and formulated as a formate salt. This engineered structure provides exceptional performance as a highly effective flocculant and retention aid in demanding water treatment and papermaking processes. It is primarily utilized by industries requiring robust solutions for solid-liquid separation, charge neutralization, and process efficiency enhancement. The product, identified by CAS No. 126720-44-3, offers reliable performance in complex aqueous systems.

Application

• Primary Flocculant in Wastewater Treatment: For the clarification of industrial and municipal wastewater, particularly effective for organic and colloidal suspensions.
• Retention and Drainage Aid in Paper Manufacturing: Improves fiber and filler retention on the wire, enhancing paper quality and mill productivity.
• Sludge Dewatering Agent: Used in centrifuges and belt presses to increase cake solids and reduce sludge volume for disposal.
• Process Water Clarification: In mining, mineral processing, and steel production to remove fine particulates from recycle water streams.
• Color and Organic Matter Removal: Effective in treating wastewater containing dyes, tannins, and other charged organic contaminants.
• Binder and Strengthening Agent: In non-woven fabrics and certain composite materials where cationic charge is beneficial.

Quality Control

Our production of this cationic polymer adheres to strict batch-to-batch consistency protocols. Quality is assured through comprehensive testing of key parameters including cationic charge density, viscosity, solids content, and pH. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to ensure the product meets your process requirements. We operate under a quality management system aligned with ISO 9001 principles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which can affect viscosity and performance. Keep away from strong alkalis and incompatible materials.
