Manufacturers, Exporters, Suppliers of Paper Chemicals in Haridwar

Haridwar's paper mills run on a different rhythm from the big mills in the south. The furnishes are often a mix of recycled fiber and virgin pulp. The paper grades span packaging, writing and some specialty lines. The water is hard in parts of the SIIDCUL belt, which affects sizing and retention. And the machine speeds are moderate, which means the chemistry has to work at the speed the machine actually runs, not at the speed the datasheet assumes. Innovacorp manufactures, exports and supplies paper chemicals for Haridwar's mills — AKD and rosin sizing agents, retention aids, wet and dry strength resins, defoamers and biocides. The working conversation starts with your furnish and machine data, not a fixed product list.

Why Haridwar's Paper Mills Face a Different Set of Decisions

Three things shape the chemistry decisions in Haridwar's paper belt. First, the furnish mix — many mills run recycled fiber alongside virgin pulp, and recycled fiber carries more fines and more contaminants, which affects retention and drainage. Second, the water quality — hard water in parts of the SIIDCUL belt affects how sizing agents and retention aids perform. Third, the paper grade mix — packaging grades need different chemistry from writing or specialty grades, and many mills run both. A retention aid that works on one furnish may underperform on another. A sizing agent that works in soft water may need a different dose in hard water. Working from the mill's own wet-end data is the only reliable starting point.

Paper Chemicals We Manufacture, Export & Supply to Haridwar

The range is grouped by function in the process, not by chemical class:

• AKD sizing agents (Alkyl Ketene Dimer): Reactive sizing for water resistance and ink holdout. Used in writing, printing and packaging grades. Requires curing time on the dryer.
• Rosin sizing agents: For acid and neutral sizing of printing and writing grades, where AKD is not the preferred route. Available in paste and dispersed forms.
• Retention aids (single and dual polymer systems): To capture fine fibers and fillers on the wire, reducing white water load and supporting consistent sheet formation.
• Wet strength resins (PAE based): For paper grades that need strength when wet — packaging, tissue and specialty grades.
• Dry strength resins: For improving tensile and burst strength in recycled-fiber furnishes, where fiber strength is lower.
• Defoamers and antifoams: For foam control in the stock preparation and white water system.
• Biocides: For slime and microbial control in the white water loop.
• Deinking aids: For recycled fiber processing, where ink removal is the target.

Grade selection depends on your furnish, machine configuration and target paper grade. We do not recommend a fixed grade for every mill.

Where Each Chemical Fits in the Wet End

Process Stage	Typical Chemical	Function
Stock preparation / pulper	Deinking aids, defoamers	Ink removal, foam control
Refining	Dry strength resins	Fiber strength development
Approach flow system	Retention aids, biocides	Fines retention, slime control
Headbox / wire	Retention aids, drainage aids	Sheet formation, water removal
Press section	—	Water removal (mechanical)
Size press / coater	Surface sizing, AKD	Surface strength, water resistance
Dryer section	Curing (for AKD)	Sizing development

The exact dosing point depends on your machine layout. Final dosing is set after a wet-end trial with your team.

Specifications

Product	Active Content	pH (as supplied)	Form
AKD sizing (emulsion)	15 – 30%	3 – 5	Liquid emulsion
Rosin sizing (paste)	70 – 80%	9 – 11	Paste
Rosin sizing (dispersion)	30 – 50%	6 – 8	Liquid dispersion

Final specification is confirmed against the product TDS for each grade.

Dosing — kg per Tonne and Dosing Point

Paper chemical dosing is set on kg per tonne of paper, and the dosing point matters as much as the dose. As a working reference for Haridwar mills:

• AKD sizing: 1–3 kg per tonne of paper, dosed at the size press or wet-end, depending on the machine configuration. Requires curing time on the dryer.
• Rosin sizing: 5–15 kg per tonne of paper, dosed at the approach flow system, with pH control for the alum-rosin reaction.
• Retention aid: 0.2–1.0 kg per tonne of paper, dosed at the approach flow system or headbox, depending on the polymer type.
• Wet strength resin (PAE): 5–20 kg per tonne of paper, dosed at the wet-end, with curing on the dryer.
• Dry strength resin: 2–10 kg per tonne of paper, dosed at the stock preparation or approach flow.
• Defoamer: 0.1–0.5 kg per tonne of paper, dosed to the foam load.

These are starting ranges. Final dosage is confirmed after a wet-end trial with your team. Our engineers work with your mill chemist on this.

Packing

• Powders: 25 kg and 50 kg HDPE bags
• Liquids: 200 kg drums and 1 tonne IBCs
• Bulk tanker supply available on request for larger mills

What Haridwar Mill Teams Usually Ask

A few questions that come up in almost every technical discussion:

• "My Cobb value is inconsistent — is it the sizing or the retention?" — Both can affect Cobb. Poor retention means fines and fillers carry through, which affects the sheet structure and the sizing distribution. We look at retention first, then sizing, because fixing retention often stabilises Cobb without changing the sizing dose.
• "Why does my retention aid work on one furnish and not another?" — Recycled fiber and virgin pulp behave differently at the wet end. Recycled fiber carries more fines and more contaminants, which can interfere with the polymer's bridging action. We check the furnish first before recommending a grade.
• "Does hard water affect AKD sizing?" — Yes, in some cases. High hardness can affect the emulsion stability and the sizing development. If your water is hard, we recommend a grade with better tolerance or a pre-treatment step.
• "Do you support wet-end audits?" — Yes. We work with your mill chemist on a wet-end audit — charge demand, retention, drainage and sizing — and recommend a dosing plan based on the findings. TDS and MSDS are shared on request.

Technical Support for Haridwar Paper Mills

We do not sell drums and walk away. For Haridwar paper mills — packaging, writing and specialty grades — we review your wet-end data, walk through the chemistry selection with your mill chemist, and support the wet-end trial. If a sheet is failing on strength, sizing or printability, call us — we will look at the machine data with you. TDS and MSDS are shared on request.
