Product Profile
Polycaprolactam (Polyamide 6, PA6)
CAS No.: 250-38-54-4
Synonyms / IUPAC Name: Polycaprolactam; Polyamide 6 (PA6)
General Formula: [–NH(CH₂)₅CO–]ₙ
Typical Density: ~1.14 g/cm³ at 23 °C
Melting Point (Tm): ~218–220 °C
Glass Transition Temperature (Tg): ~60–65 °C
Physicochemical Properties (Typical)
- Appearance: Semi-crystalline polymer, often supplied as pellets or granules
- Hygroscopy: Absorbs moisture (~2–3%), affecting mechanical properties
- Solubility: Insoluble in water; soluble in certain phenolic solvents such as o-chlorophenol and m-cresol
- Mechanical & Thermal Behavior: Good toughness, abrasion resistance, and elevated melting point suitable for engineering applications
Purity & Quality Standards
- Grade Classification: Specified by molecular weight (viscosity), pellet size, and absence of visible impurities
- Analytical Methods: Gel Permeation Chromatography (GPC) for molecular weight distribution; DSC for melting point; Karl Fischer for moisture content
- Documentation: Certificate of Analysis (COA) and Safety Data Sheet (SDS) provided with each batch
Applications / Uses
- Fibres & Textiles: Apparel, industrial fabrics, carpets, ropes
- Engineering Plastics: Moulded parts such as gears, bearings, machine components, automotive intake manifolds
- Films & Sheets: Packaging requiring strength, toughness, and thermal resistance
- Additive Manufacturing: Pellets used for filament production and composite blends
Safety & Handling
- Health Hazards: Polymer form generally low hazard; thermal decomposition may emit toxic fumes (nitrogen oxides, amines)
- Handling Precautions:
- Avoid dust generation; use adequate ventilation during machining or grinding
- Wear protective gloves and eye protection
- Storage: Store in dry environment to prevent moisture uptake affecting processing and properties
- First Aid Measures:
- Inhalation: Move to fresh air if dust inhaled
- Skin Contact: Wash with soap and water
- Eye Contact: Rinse immediately with water
- Ingestion: Seek medical advice
Packaging & Storage
- Packaging: Typically supplied in sealed bags within cartons for pellet form; larger quantities in bulk bags for industrial use
- Storage Conditions: Cool, dry, well-ventilated area; avoid direct sunlight and moisture exposure
- Shelf Life: Stable for at least 12–24 months under recommended storage; pre-drying may be required prior to processing due to hygroscopic nature
