پودر پلی (متیل متاکریلات) (PPMA)

Poly(methyl methacrylate) Powder (PMMA) is a fine, thermoplastic polymer powder composed of polymethyl methacrylate, widely used in pharmaceutical and laboratory applications for its film-forming, binding, and controlled-release properties. It is a white, free-flowing, odorless powder that is insoluble in water but soluble in certain organic solvents, forming clear, stable films when dissolved and cast.

🏭⚗️ Production
PMMA powder is produced by the polymerization of methyl methacrylate monomers via bulk, emulsion, or suspension polymerization processes under carefully controlled temperature and pH conditions. After polymerization, the material is dried, milled, and sieved to obtain a uniform, high-purity powder. For pharmaceutical and laboratory use, PMMA powder is further refined to ensure consistent particle size, purity, and performance.

🔬 Properties
PMMA powder is a white, odorless, and chemically inert material with excellent film-forming, binding, and stabilizing properties. It is insoluble in water but soluble in solvents such as chloroform, acetone, and ethyl acetate, forming clear and glossy films upon drying. It exhibits high optical clarity, mechanical strength, and stability under normal laboratory and storage conditions. The polymer is biocompatible and resistant to light, heat, and moisture, making it suitable for various pharmaceutical and analytical applications.

🧪 Applications
In pharmaceutical formulations, PMMA powder is used as a film-forming and coating agent in tablets and capsules, as well as a matrix former in sustained- or controlled-release drug delivery systems. It provides protection to active ingredients and helps modulate dissolution profiles. In laboratory environments, PMMA powder is utilized as a binder in experimental composites, a matrix material in microencapsulation, and a structural polymer in optical or analytical experiments. Its clarity and chemical inertness also make it suitable for use in optical studies and device fabrication.

⚠️ Safety
PMMA powder is generally considered safe and non-toxic for pharmaceutical and laboratory use. However, fine dust may cause mild mechanical irritation to eyes, skin, or respiratory passages. Protective gloves, goggles, and masks should be worn during handling. The material should be stored in tightly sealed containers, in a cool, dry, and well-ventilated area, away from open flames, heat sources, and direct sunlight, to preserve its stability and performance.
