PAPERMAKING AND CONVERTING

Paper process chemicals for strength, drainage and machine stability

Chemicals for paper quality and machine performance from wet end to wire section.

Overview

INDION paper-process chemicals are selected for paper quality and machine operation. The documented portfolio includes retention and drainage aids, dry-strength resins, surface-sizing agents, fluff and lint-control products, defoamers and a drainage aid. Product choice depends on furnish, paper grade, machine conditions and the target sheet properties.

Process use and chemical role

Products by paper-machine stage

Process stage or systemChemical or operational role
Wet end: retention and drainageINDFLOC 240, INDFLOC 140PG4 and INDFLOC 240PG4 are described as dual-function polymers that retain fines, fillers and fibres while improving drainage.
Wet end and sheet formation: dry strengthINDFLOC 2820, 3209, 41, 42 and 2800B strengthen fibre-to-fibre bonding, including in recycled or short-fibre furnishes.
Surface sizingINDSIZE SA230, SC201 and SA225 are used to improve surface strength and resistance to ink penetration and water.
Paper making and converting: fluff and lint controlThe POLYPLUS range is described as reducing surface lint and fluff.
Wet end and white-water systems: foam controlINDFOAM 3004 and 3040 are listed for foam and entrained-air control in wet-end and white-water systems.
Wire section: drainage aidPOLYDRAIN 243H is described as accelerating water removal on the wire section.

Benefits and intended outcomes

  • OUTCOME 1

    Retention and drainage products support retention of fines, fillers and fibres while improving drainage.

  • OUTCOME 2

    Dry-strength resins support fibre-to-fibre bonding; surface sizing supports surface strength and resistance properties.

  • OUTCOME 3

    Defoamers, lint-control products and wire-section drainage aids address specific machine-operation needs.
