The addition-vulcanizing Otoform® Xpand expands gently in the ear during impression taking. The impression material is advantageous for soft ear tissue, as it extends in the ear proportionally. In addition, it is also favorable for the fitting of hearing protection and power hearing aid systems. Otoform® Xpand guarantees a high sealing of earmolds. It is pressure building like a putty material, but allows a simple ear impression taking without much effort thanks to the creamy-fluffy consistency and excellent flowability.
