PAPER SIZING CHEMICALS
FiNe Fortified
A natural resin used to manufacture kraft paper& paperboard
> Produces more proficient sizing response.
> The Fortified rosin contains extra carboxyl groups.
> Some of the abietic acid converted into tricarboxylic species.
> Fortified rosin increase sizing efficiency consisting.
> Fortified rosin used for acidic sizing
> Fortified rosin improves resistance to penetration by aqueous fluids
FiNe DSR (Dry strength resin)
Dry strength resin used to add strength to paper
> DSR Increase bulk through reduced stock refining.
>DSR is available in three forms: anionic, cationic and amphoteric.
> DSR increase tensile strength of paper.
>DSR increase strength between fibers in any sheet of paper.
>DSR is available over a wide PH range .
> Reduce fiber costs by replacing long fiber with short fiber
> DSR is Retention aid for rosin size and other fillers.
FiNe Neutral Size
Neutral size is used to manufacture all forms of paper
> Neutral size rosine is used in neutral conditions.
>It has potentially low surface energy and thus high water repellency.
> Neutral size rosin has less foaming characters.
>Permanency of paper would be high.
>Cleaner effluent disposal system .
> Reduce fiber costs by replacing long fiber with short fiber.
>It is compatible with all types of pulps, fillers and retention aids .
FiNe AKD (Alkylketene dimer)
It is used in internal sizing of all kind of papers
> The main features are hard sizing and lactic acid resistance.
> Polymer-stabilized for neutral and alkaline sizing of paper.
> It is made from renewable raw materials.
> AKD make paper less water absorbing.
> Structurally, it is unsaturated lactones.
> AKD increases the printing properties of paper.
