a formulation of glass designed for use in electric circuitry which has particularly good electrical and heat resistance properties. E-glass is also the most common type of glass formulation used in glass-fibre reinforcements.
an inherently elastic fibre composed of at least 95% by mass of macromolecules made up of ethylene and at least one other olefin. The molecules are partially cross-linked. When the fibre is stretched to one and a half times its original length and released, it recovers rapidly and substantially to its initial length.

a fibre which possesses extremely high elongations at break and recovers fully and rapidly from high elongations up to its breaking point. The term "elastomer" is derived from "elastic polymer".
a non-conductive polymeric material which can maintain a long-lived electrostatic charge after being subjected to a strong electric field. Electret filtration fabrics made from synthetic fibres conveniently combine the mechanical removal of particles with an electrostatic field, which materially increases the filtration efficiency.
