Product overview

What Formaldehyde is used for

Formaldehyde is the simplest aldehyde — a pungent, colourless gas at room temperature, almost always supplied and handled as an aqueous solution known as formalin, typically stabilised with a small percentage of methanol to retard polymerisation. It is produced industrially by the catalytic oxidation or dehydrogenation of methanol.

Formaldehyde's single largest use is as the raw material for amino and phenolic resins — urea-formaldehyde (UF), phenol-formaldehyde (PF) and melamine-formaldehyde (MF) — which bind wood panels (plywood, MDF, particleboard), laminates and moulding compounds. It is also widely used in textile finishing (permanent-press and wrinkle-resistant treatments), and in smaller volumes as a disinfectant, biocide and biological preservative.

Where it sits in the petrochemical value chain

  • Methanol the sole feedstock formaldehyde is oxidised from. See that page.
  • Formaldehyde (this product) the resin raw material supplied as formalin solution.
  • UF / PF / MF Resins the finished adhesive resins produced from formaldehyde by wood-panel and laminate manufacturers.

Handling character

Formaldehyde is classified as a carcinogen and is acutely toxic and corrosive. Full hazard detail is in the Safety section below.

Buying from Chelora

How we supply Formaldehyde

Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Concentration, methanol stabiliser level and acidity are critical to resin-cure quality — that shapes how we manage this line.

We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window, and confirm your jurisdiction's import requirements before booking.

We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.

  • Concentration and acidity confirmed before we quote. Consistency matters to downstream resin-cure quality.
  • UN 2209 documentation managed end to end. Classification, labelling and carrier compliance confirmed before booking.
  • Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
  • Batch traceability to the producing plant. Full chain of custody documentation on request.
  • Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.
  • 37% and 44-50% grades both sourced. Matched precisely to your resin process.

Safety, storage & handling

Carcinogenic and corrosive — handle accordingly

Formaldehyde is a recognised human carcinogen and causes severe skin, eye and respiratory irritation on contact or inhalation. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.

GHS Signal word: Danger

Classified hazards

  • H301Toxic if swallowed.
  • H314Causes severe skin burns and eye damage.
  • H317May cause an allergic skin reaction.
  • H331Toxic if inhaled.
  • H350May cause cancer.

Handle only with engineering controls and full PPE. Always read the SDS issued with your specific batch and store accordingly.

Storage

Store in tightly closed containers in a cool, well-ventilated area above the solution's cloud point to prevent paraformaldehyde precipitation, segregated from oxidisers and strong bases.

Handling

Use full PPE (chemical-resistant gloves, goggles/face shield, respiratory protection) and work under local exhaust ventilation or in a fume hood. Avoid any skin, eye or respiratory exposure.

Transport

Shipped as UN 2209 (Formaldehyde solution, >25%), Packing Group III, with UN 1198 applying to methanol-stabilised flammable grades. We confirm and document exact classification for your specific shipment and destination.

Quality assurance

Every batch, documented

We verify documentation before dispatch so there are no surprises at your incoming-goods bench.

Specification agreed

Concentration, methanol content and acidity confirmed against your resin process before order placement.

The producing plant tests each batch against the agreed specification before release.

Documentation review

COA, SDS and transport paperwork checked by our desk before the shipment is booked.

Each shipment is traceable to its producing batch, with full chain-of-custody records on request.

Production background

How formaldehyde is made

Formaldehyde is produced industrially by the catalytic oxidation or dehydrogenation of methanol, typically over a silver or metal-oxide catalyst, a long-established route in petrochemical chemistry. The gaseous product is absorbed into water to form the formalin solution supplied commercially, usually stabilised with methanol.

We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
