		<description><![CDATA[Electrically conductive microspheres are produced by applying a metallic silver coating to the surface of the microspheres, thus giving the advantages of a metal particle with the additional properties of the core microsphere.  Typically hollow glass microspheres are silver coated as this offers the combination of a low density filler and a conductive particle.   Coatings with EMI shielding of greater than 45db have been produced by adding as little as 20% by weight of M-18 silver coated microspheres.]]></description>

		<description><![CDATA[
PMMA micropsheres or polymethylmethacrylate microspheres are often referred as acrylic microspheres.  PMMA polymer is an amorphous, transparent and colorless thermoplastic that is hard and stiff. It has good abrasion and UV resistance and excellent optical clarity. It has somewhat poor solvent resistance. PMMA spheres are soluble in organic solvents such as acetone, benzene, or halogenated [...]]]></description>

		<description><![CDATA[In recent years there is significant interest in using biodegradable polymeric microspheres for drug delivery. Delivering drugs through biodegradable microspheres has numerous advantages compared to conventional delivery systems. While in conventional systems the drug is usually released shortly after delivery and stops working after a brief period of time, biodegradable polymer offers a way to provide sustained release over a longer time, thus eliminating the need for multiple doses and ensuring sustained and controlled drug delivery over weeks or months.]]></description>

Polyethylene microspheres offer the added benefit of minimal residue after firing, and the availability in wide size ranges from a few micron up to 1000um (1mm).    Highly spherical microspheres have the added benefit of creating strong pores without any stress risers that might cause fracturing of the parent ceramic.]]></description>
