The most famous brand name associated with Spandex is Lycra. Spandex or elastane is a synthetic fiber known for its exceptional elasticity. It is stronger and more durable than rubber, its major non-synthetic competitor. Spandex is classified as an elastomeric fiber. An elastomer is a natural or synthetic polymer that, at room temperature, can be stretched and expanded to twice its original length. After removal of the tensile load it will immediately return to its original length. We stock fire treated lycra in many colours.
