Specialty chemicals for paper production
High demands on the quality of the various types of paper, be it in the printing and press industry, the packaging industry, the tissue paper industry, etc. necessitate a continually flexible adaptation of the process- and waste-water chemicals to the changing requirements.
Since 1991 SEPAR CHEMIE has been developing specialty chemicals for the paper industry under the brand name POLY SEPAR®.

A new generation of water based retention agents
The oil-free dispersants of the POLY SEPAR KW- and AW– range are solvent
and tensed free and are therefore particularly environment friendly.
The advantages of the POLY SEPAR KW series are:
- Mixing is easy without cumbersome solvent and dosage technology
- Less foam problems
- Reduced water consumption
- Improved filler retention
- Highest effectiveness in closed water circuits with high conductivity
Starch reduction through SEPAR® PLY BOND
A further original
product is our POLY SEPAR® PLY BOND. It is a synthetic, anion-charged
acryl-amide-copolymer, which is completely soluble in water. It is used
in the production of multilayer papers and cardboards, which are bonded
with starch. POLY SEPAR® PLY BOND is added to the water-starch solution
and is sprayed onto the paper sheets.
The advantages of POLY SEPAR® PLY BOND are:
• Increases the adhesion between the paper sheets
• Partially replaces the starch at a ratio of 1/10
• Considerable cost savings
• Applicable in a wide pH-range
• Reduces the COB burden through reduced starch consumption
High molecular flocculation aids for waste paper processing
offer with our POLY SEPAR® K 5—range extremely high molecular
flocculation aids for highest efficiency in flotation plants. All
products in this range are produced in "paper grade" quality with fast
and residue-free solubility. They are subject to the stringent criteria
of the XXXVI recommendations of the BfR, in order to be used for tissue
papers and food packaging.
An overview of our products
Fresh water preparation
We use our flocculation aids to treat raw water for the paper production and to free it from spurious impurities.
POLY SEPAR® flocculation aids guarantee high-quality waste-water treatment and sludge dewatering with a high dry content.
Our bacterio-static agent POLY SEPAR® KS 300 reduces and inhibits odour causing bacteria.
The water-based retention agents from our POLY SEPAR® KW /AW–range are solvent and tenside free.
To reduce starch in cardboard and paperboard production we recommend POLY SEPAR® PLY BOND.
POLY SEPAR® Bent is used to speed up the dewatering process. It improves the adsorption of contraries and therefore retention.
avoid crystalline deposits in the paper machine, especially with
suction rolls, filters and wires, POLY SEPAR® C 5 is suitable.
To improve dry strength we offer the POLY SEPAR® DS 1.
