E-glass:
- 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.

Elastane:
- a man-made fibre containing at least 85% polyurethane which is capable of high stretch followed by rapid and substantial recovery to its unstretched length. (See also elastomer; elastomeric yarn.)

Elastane, elastomeric:
- a fibre, often made of polyurethane, possessing inherent stretch properties (also known as spandex, especially in the USA).
|
-
Elastolefin:
- a fibre composed of at least 95% (by mass) of macromolecules—partially cross-linked—made up of ethylene and at least one other olefin. When it is stretched to one and a half times its original length and released, the fibre recovers rapidly and substantially to its initial length.

-
Elastomer:
- a polymer which has high extensibility together with rapid and substantially complete elastic recovery. (See also elastane; elastomeric yarn.)

Elastomeric yarn:
- a yarn formed from an elastomer.

Elastomeric yarns:
- yarns whose structure gives them good stretch and recovery properties. The Elastomeric yarns based on polyurethane are called elastane, or spandex in the USA and parts of Asia. The terms elastane and spandex do not, however, include stretch polyamide fibr

Electret:
- a non-conductive polymeric material which can maintain a long-lived electrostatic charge. Polypropylene electret filtration fabrics conveniently combine the mechanical removal of particles with an electrostatic field, which materially increases the filtration efficiency.
|
-
Electrospinning:
- in established versions of the electrospinning process, a polymer solution or molten polymer is given an electrical charge and forced through a capillary. As the charge is increased, a jet of polymer is emitted from the capillary and coalesces in the form of very fine fibres, up to 500 times thinner than a human hair.

Elité:
- a brand name used by Nylstar for its PBT (polybutylterephthalate) fibre.
