Manufacturers, Exporters, Suppliers of Paper Chemicals in Sonipat

A paper machine is a balance. Change the retention aid, and the drainage changes. Change the drainage, and the steam demand changes. Change the sizing, and the Cobb value moves. Get the balance right, and the machine runs at speed with a consistent sheet. Get it wrong, and the same furnish produces a sheet that fails on strength, sizing or printability. Innovacorp manufactures, exports and supplies paper chemicals for Sonipat's paper, board and packaging mills — AKD and rosin sizing agents, retention aids, wet and dry strength resins, defoamers and biocides. The working conversation starts with your wet-end data, not a fixed product list.

Why Paper Machine Chemistry Is a Balance, Not a Recipe

Paper mills in Sonipat run a range of furnishes — virgin pulp, recycled fiber, and blends of both. Each furnish behaves differently at the wet end. Recycled fiber carries more fines and more contaminants, which affects retention, drainage and sheet strength. Virgin pulp gives better strength but costs more. The chemistry has to compensate for whichever furnish the mill is running. This is why there is no single "best" retention aid or sizing agent — the right chemistry depends on the furnish, machine speed, target paper grade and the specific problem you are trying to solve. A retention aid that improves drainage on one machine may cause formation issues on another. A sizing agent that works on one furnish may underperform on a recycled furnish. Working from the mill's wet-end data is the only reliable starting point.

Paper Chemicals We Manufacture, Export & Supply to Sonipat

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.

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

Dosing — kg per Tonne of Paper

Paper chemical dosing is typically set on kg per tonne of paper produced, not on ppm in water. As a working reference for Sonipat mills:

• AKD sizing: 1–3 kg per tonne of paper, depending on the target Cobb value and furnish.
• Rosin sizing: 5–15 kg per tonne of paper, depending on the furnish and the sizing level required.
• Retention aid: 0.2–1.0 kg per tonne of paper, adjusted to the furnish fines content and machine speed.
• Wet strength resin (PAE): 5–20 kg per tonne of paper, depending on the wet strength target.
• Dry strength resin: 2–10 kg per tonne of paper, depending on the furnish and strength target.
• 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 Paper 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.
• "Can I switch from rosin to AKD without changing the machine?" — Yes, but the change needs to be planned. AKD needs curing time on the dryer, and the wet-end pH usually shifts. We recommend a trial run with your team before committing to the switch.
• "Why is my white water load so high?" — Usually a retention issue. If fines and fillers are not being captured on the wire, they carry through to white water, which increases load on the save-all and the ETP. A retention aid trial is the usual starting point.
• "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 Sonipat Paper Mills

We do not sell drums and walk away. For Sonipat paper mills — packaging, board, writing and printing 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.

Where can I find AKD sizing agents in Sonipat for paper mills?

Innovacorp supplies AKD sizing agents for paper and board production in Sonipat. AKD sizing improves water resistance and ink holdout on the sheet. The specific grade and dose depend on your furnish and target Cobb value — share your process data and we can advise.

How do retention aids help Sonipat paper mills?

Retention aids help capture fine fibers and fillers on the wire, which reduces the load in white water and supports more consistent sheet formation. The exact benefit depends on your furnish, machine speed and current retention level. We work from your machine data before recommending a grade.
