lignin

LigninCorp supplies industrial lignin as a black powder that does not dissolve in water. Lignin is the natural phenolic polymer that binds wood fibres together; our lignin is recovered from pulping and supplied with TDS, SDS and a COA for each batch.

Key Properties

  • Black powder with 50% min lignin content.
  • Not soluble in water: it stays as a solid in water-based systems, which suits fillers, fuels and solid blends.
  • Mildly acidic: pH 4 – 6.
  • Sugar-free: reducing sugar 0%.

Lignin is not the same as lignosulfonate. Lignosulfonates are sulfonated lignin and dissolve readily in water; see sodium lignosulfonate and calcium lignosulfonate if you need a water-soluble product.

Uses Listed in the TDS

  • Raw material and by-product fuel in the pulp and paper industry
  • Feedstock for bioenergy (pyrolysis, gasification)
  • Source of phenolic compounds for resins and adhesives
  • Research and development of carbon fibre and bio-based plastics and composites
  • Lignin-rich input in agricultural and feed applications

What to Tell Us When You Order

  1. Your application and the property that matters most.
  2. Any limits on lignin content, pH or moisture.
  3. Packing, volume and destination port.
  4. Documents you need (TDS, SDS, COA).

Packing and Storage

  • 20 or 25 kg woven bags with polyethylene liner; custom packing on request.
  • Store cool, dry and ventilated; avoid prolonged exposure to moisture and reseal opened bags.

Frequently Asked Questions

What colour is lignin?

Black. Our lignin is a black powder.

Is lignin soluble in water?

No. Lignin does not dissolve in water. For water-soluble lignin products, use lignosulfonates.

What is the lignin content?

50% min according to the TDS, with pH 4 – 6 and 0% reducing sugar.

What is lignin used for?

As a raw material and fuel, a source of phenolic compounds for resins and adhesives, in bio-based materials development and as a lignin-rich input in agricultural and feed applications.

How is lignin packed?

20 or 25 kg woven bags with polyethylene liner; custom packing on request.
