1. Degree of Substitution The degree of substitution significantly impacts HEC's viscosity. A higher degree results in increased hydrophilicity and solubility, leading to higher viscosity solutions. Manufacturers can tailor HEC grades to meet specific viscosity requirements for different applications.
3. Water Retention Gypsum plaster tends to lose water rapidly, which can lead to premature setting and cracking. HPMC enhances water retention by forming a gel-like structure in the mix, allowing the plaster to remain workable for an extended period while providing adequate hydration for proper curing. This property is crucial for achieving optimal strength and durability of the final product.
The HS code for Hydroxypropyl Methylcellulose falls under the broader category of polysaccharides and derivatives. Generally, HPMC is classified under HS Code 3912, which pertains specifically to “Cellulosic and cellulose derivatives.” However, the precise classification may vary slightly depending on regional interpretations and additional modifications of the substance. It is crucial for manufacturers and exporters to consult local customs authorities or trade experts to ensure compliance with the correct HS code and avoid potential issues during the shipping process.
