🧪 Paraformaldehyde – Product Description (English)

Chemical Identity

• Name: Paraformaldehyde

• Synonyms: Formaldehyde polymer, Polyoxymethylene precursor, Paraform, Trioxane (historical)

• CAS Number: 30525-89-4

• Formula: (CH2O)n

• Appearance: White crystalline solid or granules, with a sharp formaldehyde odor

Physical Properties

• Melting/Softening Range: 120–170 °C (depending on polymerization degree)

• Solubility: Insoluble in water; hydrolyzes to release formaldehyde solution

• Odor: Strong, characteristic formaldehyde smell

• Stability: Stable in dry conditions; depolymerizes upon heating or in moist environments

Chemical Properties

• Reactivity: Highly reactive aldehyde polymer; source of formaldehyde in controlled release

• Molecular Weight: Variable, depending on chain length (typically 8–100 monomer units)

• Flammability: Classified as a flammable solid (UN 2213, Class 4.1); combustion releases toxic gases (formaldehyde, CO, CO₂)

Applications

1. Laboratory & Biotechnology

   • Used for tissue and cell fixation in immunohistochemistry and microscopy

   • Provides controlled release of formaldehyde for stable fixation solutions

2. Resin & Adhesive Manufacturing

   • Raw material for phenol-formaldehyde, urea-formaldehyde, and melamine-formaldehyde resins

   • Acts as a hardener in plywood, MDF, and laminate adhesives (PRF systems)

3. Agriculture & Livestock

   • Disinfectant for barns and poultry houses

   • Soil sterilization and fungal control (fumigant applications)

4. Pharmaceuticals & Cosmetics

   • Antimicrobial additive in formulations requiring slow formaldehyde release

   • Limited use due to regulatory restrictions on formaldehyde-releasing agents

5. Polymers & Plastics

   • Intermediate for polyoxymethylene (POM) production, a high-strength engineering plastic

   • Used in precision plastic components with high stiffness and durability

6. Paper & Textile Industry

   • Improves paper strength and dimensional stability

   • Applied in textile finishing (wrinkle resistance, surface treatments)

Safety & Handling

• Hazards: Irritant to eyes, skin, and respiratory tract; potential sensitizer and carcinogen (due to formaldehyde release)

• Protective Equipment: Gloves, goggles, respirator, lab coat required

• Storage: Cool, dry, well-ventilated area; avoid moisture and ignition sources

• Transport: UN 2213, Class 4.1 (Flammable solid) – ADR/IMDG compliant packaging required

🔍 Sectoral Suitability Overview

⚠️ Safety & Compliance Reminders
