Paper Additives designate a group of Paper Additives that are used for paper manufacturing, or modify the properties of paper. These Paper Additives can be used to alter the paper in many ways, including changing its color and brightness, or by increasing its strength and resistance to water.
The Paper Additives can be defined on basis of their usage in the process. Paper Additives usage is not only for imparting properties to paper but to handle the water cycles in the process, conditioning of fabrics, cleaning of equipment and several other applications.
Paper Additives pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of Paper Additives pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semiPaper Additives is treated as a third process separate from sulfite, and soda pulping which is the least ecologically hazardous utilizing sodium hydroxide or anthraquinone.
Caustic soda is added to increase the pH in the pulping process of fibers. The higher pH of the paper-fiber solution causes the fibers to smoothen and swell, which is important for the grinding process of the fibers.
Dry-strength additives, or dry-strengthening agents, are chemicals that improve paper strength normal conditions. These improve the paper’s compression strength, bursting strength, tensile breaking strength, and delamination resistance.
Typical chemicals used include cationic starch and polyacrylamide (PAM) derivatives. These substances work by binding fibers, often under the aid of aluminum ions in paper sheet.
The Global Paper Additives market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Clariant’s paper additives – High-speed state-of-the-art papermaking requires reliable and efficient additives. Clariant’s paper additives OPAZIL , OPAZIL FFR and PITCHBENT offer an innovative and cost-reducing solutions for reliable and productive papermaking: from pulper to reel.
Based on selected bentonites, OPAZIL grades improve retention and optimize forming for all kind of papers. In addition, they keep the system clean and simplify waste water treatment. PITCHBENT additives eliminate even colloidal micro-stickies and enable papermakers to recycle process water more often and use more de-inked recycled paper – for more sustainability in papermaking.
