Dyna Glycols manufactures surfactants and process aids for pulp and paper: EO/PO pretreat and defoamers, de-inking detergents, sizing companions, dyeing aids, bleaching aids, sheet-making lubricants and retention aids, plus carbamate slimicides and felt-cleaning blends. Grades are specified by process step, not by a mill nickname. A de-inking detergent, a defoamer and a slimicide are different duties.
What paper chemicals are
Dyna Glycols manufactures surfactants and process aids for pulp and paper: EO/PO pretreat and defoamers, de-inking detergents, sizing companions, dyeing aids, bleaching aids, sheet-making lubricants and retention aids, plus carbamate slimicides and felt-cleaning blends. Grades are specified by process step, not by a mill nickname.
A de-inking detergent, a defoamer and a slimicide are different duties. Write the machine (stock prep, de-ink, size press, dye, bleach, sheet, felt) and whether APEO or silicone is allowed.
How Dyna Glycols manufactures paper chemicals
EO/PO copolymers, fatty acid ethoxylate derivatives, fatty alcohol ethoxylates, quaternaries, polyethylene derivatives, wax sizes and carbamates are produced on the same network used for industrial non-ionics and esters, then finished for mill floats. Alkyl-capped EO/PO defoamers are offered as mineral-oil-free and silicone-free knockdown.
Custom blends of non-ionic surfactants and amine derivatives are quoted as felt (roller) cleaners after the soil and machine type.
Typical grades in this range
Start from the mill step. Typical catalogue families are listed below.
- Pretreat: EO/PO copolymers (anti-foam); non-silicone defoamers; quaternized stearamide for pulp strength; alkyl-capped EO/PO defoamers (mineral-oil and silicone free)
- De-inking: aliphatic acid ethoxylate derivatives (with and without flotation); aliphatic acid detergents with froth; solvent-containing grades for stubborn ink; APEO-free EO/PO de-ink polymers
- Sizing: modified rosin; polyethylene-derivative for kraft; synthetic wax for lustre
- Dyeing aids: quaternary for blotting and unsized acid dyeing; fatty alcohol ethoxylates for pastel levelling
- Bleaching: non-ionic brightness aids; non-silicate peroxide stabilisers
- Sheet making: fatty acid derivatives to reduce cylinder tack; nitrogenous polymer retention aids
- Special: carbamate antimicrobials for slime-forming bacteria, algae and fungi; non-ionic plus amine felt-cleaning detergents
Where paper chemicals are used
De-ink plants without flotation use ethoxylated aliphatic acid derivatives for brightness. Plants with flotation use frothing detergents so ink particles leave with the foam. Stubborn ink may need a solvent-containing companion — confirm mill VOC and safety rules first.
Size press and kraft use rosin, PE-derivative or wax companions as listed. Dyeing of tissue and unsized paper uses a quaternary that should not kill absorbency. Peroxide bleach uses a non-silicate stabiliser so residual peroxide stays in the bath.
How to specify paper chemicals
Name the step, furnish (virgin, OCC, mixed waste), APEO and silicone policy, foam test, and brightness or sizing target. For de-inking say whether flotation is present. For slimicides name sodium vs potassium carbamate and % active.
If replacing a competitor de-inker or defoamer, attach ionic type, cloud point or active and the mill pH.
Quality, documents and supply
Lots are released against the tests on the TDS. SDS and COA follow verification. Brightness, foam and sizing must be checked on the customer furnish.
Store liquids above pour point. Follow the SDS for carbamates and solvent-containing de-inkers. Protect from frost where water is the solvent.
Practical notes on paper chemicals
Silicone vs non-silicone defoamers change spots on the sheet. If silicone is banned, order the alkyl-capped EO/PO or non-silicone type, not a mill-oil defoamer from another supplier mixed in by habit.
Related pages: EO/PO block copolymers, fatty acid ethoxylates, fatty alcohol ethoxylates, sugar chemicals (carbamates). Sample defoamer and de-inker separately.
Quaternized stearamide is a strength aid, not a defoamer. Retention polymer is not a size. Order by duty.
Carbamate slimicides are mill-water biocides. Confirm the mill still permits that chemistry and the residual limits on the sheet.
Felt cleaners are custom blends. Send felt type, temperature and soil (pitch, stickies, coating) rather than a warehouse nickname.
English is the source language for APEO, silicone and biocide claims.
Ordering and evaluating paper chemicals
Send the application, the analytical window and the pack size when you request a laboratory sample of paper chemicals. SDS, TDS and COA follow a short company check. Handle and store the grade as the SDS describes.
