For professionals involved in procurement, R&D, and quality control, understanding the detailed specifications of raw materials is fundamental to successful product development and manufacturing. Welan Gum (CAS 96949-22-3), a sophisticated microbial polysaccharide, requires precise parameter management to ensure optimal performance in its diverse industrial applications. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, provides this essential guide to Welan Gum specifications, empowering our clients to make informed decisions.

The primary characteristic that makes Welan Gum so valuable is its rheological behavior, specifically its viscosity. Typically, Welan Gum is specified by its viscosity, often measured as a 1% solution in 1% KCl using a Brookfield viscometer (e.g., LVT, 60 rpm, Spindle 3) at 25°C. Minimum viscosity requirements, such as ≥ 1500 mPa.s, are common and critical for applications like cement additives and drilling fluids. Different grades may have varying viscosity profiles, and selecting the appropriate one is key to achieving desired performance. We ensure our Welan Gum meets these high viscosity standards, offering a premium product.

Appearance is another important visual indicator of quality. Welan Gum typically presents as a white to off-white powder. Any significant deviation in color, such as a strong tan or brown hue, might suggest impurities or degradation, affecting its performance. Our manufacturing processes are designed to produce a consistently white to off-white powder, ensuring visual quality and purity.

The pH of a 1% Welan Gum solution usually falls within a neutral range, typically 5.0-9.5. This stability across a broad pH spectrum contributes to its versatility in various formulations. Consistent pH is crucial for maintaining the integrity and functionality of the Welan Gum in different chemical environments. We ensure our product's pH remains within the specified range, confirming its reliability.

Loss on drying (LOD) is a measure of moisture content. For Welan Gum, a maximum LOD of around 13.0% is standard. Excessive moisture can affect the powder's flowability, storage stability, and the effective concentration of the active ingredient. Our production and packaging methods are optimized to minimize moisture content, ensuring product stability and accurate dosing.

Particle size is also a relevant specification, often described by the percentage passing through a specific mesh sieve, such as 95% through 80 mesh. This influences solubility and dispersion rates. A fine, consistent particle size ensures easier incorporation into formulations and faster dissolution, which is beneficial for efficient manufacturing processes. We pay close attention to achieving the desired particle size distribution for our Welan Gum.
