Polymer is a very broad term that encompassed a large amount of materials. The world “polymer” refers to materials that are composed of repeating identical molecules.

The type of molecule, the length of the chain, the amount of cross-linking, the presence of various chemical groups – all affect the behavior as well as chemical and physical properties of the material.

Many different polymers can be used as raw materials for hollow glass microspheres. The most common polymer microspheres are made from polyethylene, polystyrene, and poly(methyl methacrylate).
