Process Chemicals

The basis for high-quality paper and cardboard is already laid in the paper manufacturing process. The DESPUMOL 661defoamers from Schill+Seilacher take this into account. Effective ventilation at the paper machine is part of every process optimization and a prerequisite for optimum sheet formation. This principle also applies to the earlier stages of fibre recovery from waste paper, where FLOKUTAN 71 enables an effective ink discharge and a reduction of impurities in the deinking process with reliable foam development. 

EVORAL RA as release agent contributes to a clean separation of the mouldings from the sieves of less strongly cleaned waste paper fibres, which are often used for mouldings.

EVORAL K 350

Improves the dimension stability and the flatness of the paper. It also reduces dusting.

EVORAL M 308

Provides the sizing. Renders the sheet more flexible and more supple, and both surface dust and cutting dust are bound.

EVORAL RA 101

Suitable for the manufacture of moulded paper.
