PMMA Microspheres

Product Description

As a professional supplier of plastics and related services, Alfa Chemistry offers a comprehensive range of polymethyl methacrylate (PMMA) microspheres, designed to meet the demanding needs of advanced research, industrial development, and high-precision applications. Our PMMA microspheres are produced using suspension polymerization of methyl methacrylate (MMA) monomers. PMMA microspheres are solid, spherical white particles known for their high surface area, strong adsorption properties, and robust surface reactivity. These PMMA microspheres can be evenly dispersed in pure water, forming a milky white suspension.

• Materials: PMMA
• Particle size range: Customizable from 20 nm to 300 μm
• Packaging options: 10ml, 20ml, 50ml, 100ml, 500ml, 1,000ml

Key Features and Benefits

• Monodisperse Particle Size: We offer PMMA microspheres with highly uniform particle sizes, ranging from 20 nm to 300 µm, with customization options available.
• Unique Surface Properties: Characterized by a large specific surface area, strong adsorption capabilities, significant cohesive effects, and high surface reactivity. Our crosslinked variants notably feature a rough surface with strong hydrophobicity.
• High Purity and Stability: Manufactured from high-quality methyl methacrylate (MMA) monomers, resulting in a pure, white spherical solid with excellent stability over time and under various conditions.
• Versatile Dispersibility: While inherently hydrophobic (for crosslinked types), they can be uniformly dispersed in pure water to form a milky white liquid. Dispersion can be further enhanced by adding ethanol to reduce surface tension and through sonication.

Application Areas

The versatility of PMMA microspheres makes them invaluable across numerous sectors:

• Biomedical Innovations: From controlled drug delivery systems and embolization agents to components in advanced medical devices, their biocompatibility and precise dimensions are highly valued.
• Filtration and Detection: Their porous nature and adaptable surface chemistry render them perfect for use as efficient filtration media and as robust solid-phase supports in a variety of detection assays.
• Fluid Dynamics Research: They serve as reliable tracer particles for visualizing and analyzing complex flow patterns.
• Chromatography and Separation: Their monodisperse nature and controlled surface properties contribute to highly efficient separation processes in chromatographic columns.
• Microscopy and Cell Measurement: Their uniform size and spherical shape make them excellent calibration standards, precise markers, and ideal components for cell counting and sizing in biological research.
• Optical Materials: PMMA's inherent transparency and optical clarity allow for its integration into light-diffusing films, optical sensors, and other specialized optical components.
