For professionals in the chemical and manufacturing sectors, understanding the precise specifications of raw materials is fundamental to ensuring product quality and process efficiency. Massoniana Rosin (WW GR) is a key industrial chemical, primarily used in papermaking, but also valuable in inks, adhesives, and coatings. This article provides a comprehensive overview of its specifications and guides procurement professionals on how to source this critical material effectively.

Understanding the Specifications of Massoniana Rosin (WW GR)
Our Massoniana Rosin (WW GR) is meticulously produced to meet exacting industrial standards. The key specifications are:

• CAS No.: 8050-09-7 - This universally recognized identifier ensures you are procuring the correct chemical compound.
• Material: 100% Massoniana - Guarantees a natural, high-quality source, free from artificial additives or less desirable rosin types.
• Appearance: Transparent Solid - Indicates purity and absence of significant contamination, a crucial visual cue for quality.
• Color: Pale yellow - A typical and acceptable color for high-grade rosin, suggesting minimal oxidation or degradation.
• Softening Point (R&B): 68~76℃ - This is a critical parameter for many applications, especially in hot-melt adhesives and inks, defining its processing temperature window.
• Acid Value (mgKOH/gr): 163~166 - A high acid value is characteristic of rosins used for sizing, contributing to their reactivity and effectiveness in forming films and dispersions.
• Alcohol Insoluble Substance (%): ≤ 0.03 - Extremely low levels of insolubles ensure smooth processing and prevent clogging in application systems.
• Unsaponifiable Matter (%): ≤ 5 - A low percentage of unsaponifiable matter indicates high purity and efficient saponification when required.
• Ash (%): ≤ 0.02 - Minimal ash content signifies the absence of inorganic impurities, vital for sensitive chemical formulations.
