With the DURAN®+, the DURAN® product group is supplemented by a thermoforming film with applied insulating film. The thermoforming process is reduced by one step, as there is no longer any need to thermoform a separate insulating film in advance. The hard elastic, transparent material bonds well with autopolymers (e.g. DURASPLINT) and is suitable for miniplast, bite, interim and fluoridation splints, X-ray templates, snoring therapy devices, temporary crowns and bridges.
