Key Features and Benefits
- Customizable Surface Functionalities: A key advantage of our PE microspheres is their modifiable surface. We supply both "bare" (unmodified) spheres and those functionalized with a variety of reactive groups. These include amino, carboxyl, hydroxyl, and thiol groups, allowing for specific chemical conjugations.
- High-Purity Preparation: We primarily utilize the template method for manufacturing our PE microspheres. This sophisticated technique involves using a sacrificial template (such as polystyrene) as a scaffold, onto which PE is precisely deposited. The template is then removed, yielding high-purity PE microspheres with a typical PE content of 70%.
- Adjustable Solid Content: Our standard solid content for liquid suspensions is 2.5%, with options for customization to meet specific concentration requirements.
- Tunable Density: The density of PE microspheres can be precisely adjusted by modifying their composition and internal structure. This allows for tailored buoyancy characteristics, making them ideal for applications such as fluid visualization studies where specific suspension properties are critical.
- Excellent Chemical Stability: Inherently hydrophobic, PE microspheres can be treated with surfactants to improve their dispersibility and stability in aqueous solutions, broadening their applicability in water-based systems.
Application Areas
The unique properties of PE microspheres make them indispensable across a wide range of sectors:
- Biomedical Applications: Their biocompatibility and modifiable surfaces make them excellent candidates for advanced drug delivery systems, where they can serve as carriers for targeted therapeutic agents.
- Cosmetics and Personal Care: In the cosmetics industry, PE microspheres are widely used as micro-beads or carriers due to their physical stability and safety. They contribute to product texture and can encapsulate active ingredients. Our products are suitable for easy integration and detection in formulations, as demonstrated by their stable chemical structure during extraction and analysis.
- Environmental Monitoring: PE microspheres play a crucial role in environmental monitoring, particularly in the detection and identification of microplastics. Their robust nature and detectability make them valuable reference materials for analytical techniques such as Pyrolysis-GC/MS (Gas Chromatography-Mass Spectrometry), aiding in the accurate assessment of environmental microplastic contamination.
- Materials Science: As components in advanced materials, PE microspheres can improve properties such as abrasion resistance, lubricity, and thermal insulation in various composites and coatings.
- Fluid Mechanics Research: Their tunable density and uniform spherical shape make them ideal for fluid visualization experiments, helping researchers understand flow patterns and fluid dynamics.
Storage and Handling
- Storage conditions: Store sealed at room temperature or 4°C.
- Crucial note: DO NOT FREEZE. Freezing can lead to irreversible aggregation and damage to the microsphere structure, significantly impacting their performance.
- Shelf life: With proper storage, our PE microspheres boast a reliable 12-month shelf life.
