Product Description

Intraplast Z is a ready to use injection aid in powder form. It is non-toxic, nonflammable and does not contain chlorides or other ingredients of a corrosive nature.

Intraplast

Z causes the cement mixture to expand before setting. The swelling is caused by the extremely regular formation of densely distributed tiny gas bubbles consisting of inert hydrogen. These very tiny pores give the set material a high

degree of frost resistance.
