The technical cellulose fibre products we sell are manufactured by CFF in Germany and are used in asphalt road construction. Only natural and recycled raw materials are processed for this purpose.

TOPCEL® cellulose fibre products are successfully used as binder carriers in asphalt road construction worldwide. They are made from a specially developed technical cellulose.

It is used worldwide as a binder carrier for the production of Stone Mastic Asphalt (SMA), Semi-Dense Asphalt (SDA), Open-Pore Asphalt (OPA), high stability binder courses as well as in binder-rich special construction methods.
