Specialty paper and technical paper
Decor papers, thermal papers and filter papers are just a few examples of this type of paper. And each faces different demands, such as strength, processability, recyclability and quality in use. We offer an expandable product range for the production of these different papers.
Synthetic dry strengtheners
DEFOBOND AL 6606
- Medium to high molecular weight, low anionic polyelectrolyte based on an acrylamide derivative
- Mode of action is based on a charge exchange between the electrical charges along the polymeric chain present in aqueous solution and the surface charges of the suspended solid particles
- Appearance: colorless to slightly yellowish liquid
Process auxiliaries
DEFOKALK® 450 FD
- Highly efficient product based on calcium hydroxide in suspension form for complete sanitation of the water cycle
- Regulates pH and reduces water hardness and organic acids in a fast reaction time
- Strengths of the paper are increased and the effectiveness of other auxiliaries used is improved
- Appearance: milky-white suspension / active ingredient (%): 45
Defoamer
DEFOSPUM® PWW 90
- Emulsion of fatty alcohols, without silicone and mineral oil components for application on the paper machine and in wastewater treatment plants
- Very effective in a wide pH and temperature range
- Biodegradable and approved according to FDA and BfR XXXVI recommendation
- Appearance: white emulsion / viscosity (mPas): 250
DEFOSPUM® PWW 74
- Emulsion of fatty alcohols, without silicone and mineral oil components for application on the paper machine and in wastewater treatment plants
