Unsticking the potential

Pitch and stickies are the bane of paper production and recycling.Our special polymers from the Cartaspers® range solve that sticky old problem in different ways.

Cartaspers® PLH is a highly efficient mildly anionic polymeric surfactant for the passivation of pitch and stickies in pulping and papermaking operations. It is specifically designed for high performance in soft water environments.

Also of note, Cartaspers® PSM which is a non-ionic, biodegradable hydrophilic polymer with a high affinity for hydrophobic surfaces. Its unique properties provide a myriad of uses in the paper industry.

Cartaspers® SCS is a novel water based polymer emulsion for the wet-end prevention of stickie contamination which improves paper machine cleanliness and runnability.

Cartaspers® is easy to use, effective in a wide variety of environments and reducing negative downtime effects of stickies which leads to increasing productivity of paper production.

Superior performance with recycled fibre

Cartafen® is an additive with a novel capability. Targeted specifically at all forms of recycled fibre, it can partially replenish the anionic charge at the fibre surface, incresing the 'demand' for cationic additives. The performance of the traditional cationic components in a paper machine wet-end is therefore enhanced. The effect is particularly apparent in relatively closed systems, where conductivity levels would normally retard the adsorption of cationic additives.

Increased productivity and deep shades

Further gains in productivity during papermaking and pulping processes can be achieved with our fiber activation, retention and foam control solutions from the Cartafen®, Cartaretin® and Antimussol® ranges. In dyeing processes, our fixatives from the Cartafix® range improve backwaters, bleedfastness, dyestuff yield and enable production of deep shades.
