The Electrospinning Technology

Electrospinning is an established technique for the manufacture of fibrous components for medical devices. During electrospinning, a viscous solution is fed through a needle using a syringe pump. A high voltage of up to 30,000 volts is applied to a needle, ejecting a thin jet of the solution. The jet accelerates towards a target collector held at an opposite potential and thins considerably during flight. Dried fibres are deposited as a non-woven mat, with individual fibres being about 10 to 100 times thinner than the width of a human hair. Electrospun fibres can be used as simple mats and cut to shape with fibres of random, aligned or layered orientation. The technique also allows for the manufacturing of more specific structures like tubes or the coating of complex geometries. Different polymers can be used for this process resulting in permanent or resorbable devices as well as ones with opaque or transparent appearance. The Electrospinning Company is a globally leading manufacturer of electrospun biomaterials for medical devices that can be used in a variety of clinical applications.
