Product Name: Polyamide 6 (Nylon 6, PA6)
Chemical Family: Polyamide resin
CAS Number: 25038-54-4
Monomer: Caprolactam
Product Codes: Common brand and trade names may include Ultramid, Nylatron, Technyl
Recommended Use: Engineering plastics, fibers, films, automotive parts, electrical components
Supplier Information: Name, address, emergency contact number as supplied by the manufacturer
Emergency Phone: 24-hour hotline number as provided by supplier
Hazard Classification: Not classified as hazardous by GHS for solid, finished form
Physical Hazards: Dust may form explosive mixture in air during processing or grinding
Health Hazards: Inhalation of dust causes respiratory irritation; melted material can cause thermal burns; no mutagenic, carcinogenic, or reproductive toxicity found in typical uses
Environmental Hazards: Product forms persistent residues but does not show acute toxicity to aquatic life
Label Elements: None required for solid plastic; processing vapors may warrant warning about irritation
Signal Word: None for solid
Substance: Polyamide 6 resin
CAS Number: 25038-54-4
Content: >95% by weight as polymer
Additives: Minor content of heat stabilizers, colorants, glass fiber (if reinforced)
Impurities: Trace monomer caprolactam below 1%, possible processing aids and lubricants
Decomposition Products: May include ammonia, nitrogen oxides, caprolactam vapors when exposed to high heat
Inhalation: Move to fresh air; seek medical attention if symptoms persist; administer oxygen for respiratory distress
Skin Contact: Wash affected area with soap and water; seek medical help for exposure to molten polymer causing burns; do not remove material stuck to skin—cool rapidly with water
Eye Contact: Rinse cautiously for several minutes, remove contact lenses, seek medical attention if irritation remains
Ingestion: Rinse mouth with water, do not induce vomiting unless instructed; seek medical care if discomfort occurs
Symptoms: Mechanical irritation or redness, cough from dust, burns from hot material
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Media: Direct water jet in confined fires may spread molten material
Specific Hazards: During combustion releases irritating and toxic gases (ammonia, carbon monoxide, nitrogen oxides)
Protective Equipment: Full protective suit, positive pressure self-contained breathing apparatus
Special Procedures: Cool containers exposed to fire with water spray, prevent runoff from entering drains or waterways
Personal Precautions: Wear appropriate respiratory, eye, and skin protection; avoid dust generation; areas with insufficient ventilation need local exhaust
Environmental Precautions: Prevent further spillage; avoid contamination of drains, watercourses, and soil
Clean-Up Methods: Sweep or vacuum up spilled pellets or powder; use non-sparking tools; transfer to suitable containers for recycling or disposal
Decontamination: Flush spill area with water if needed to remove fine dust; remove all sources of ignition where dust is present
Handling: Use in well ventilated area; avoid dust, inhalation of fumes, direct skin contact with hot material; take precautions against static discharges; ground or bond containers
Storage Conditions: Store in a dry, cool, well-ventilated place; protect from moisture and direct sunlight; keep away from open flames or sources of ignition
Package Materials: Store in original unopened containers if possible; reseal packages securely after use to avoid contamination
Incompatibilities: Avoid strong acids, bases, and oxidizing agents
Occupational Exposure Limits: No specific limits for PA6; for nuisance dust, refer to local regulations (typically 10 mg/m3 for total dust)
Engineering Controls: Use local exhaust ventilation at sources of dust or vapor generation; process enclosures for high-temperature work
Personal Protective Equipment: Gloves (heat resistant for molten material), safety glasses or goggles, long sleeves, dust mask or respirator if dust exceeds recommended limits
General Hygiene: Wash hands thoroughly after handling; avoid eating, drinking, or smoking in processing areas
Environmental Controls: Proper ventilation or containment to prevent release of dust or fumes into workplace and environment
Appearance: White to off-white granules or pellets (may be colored)
Odor: Mild or odorless, possible amine-like when heated
Melting Point: 210–225°C
Boiling Point: Not applicable (decomposes before boiling)
Decomposition Temperature: Around 300°C
Flash Point: >300°C
Auto-Ignition Temperature: Approx. 450°C
Flammability: Will burn under fire conditions
Solubility (water): Insoluble
Specific Gravity: 1.12–1.15
Vapor Pressure: Not relevant
Particle Size: Pellets, granules, or powder
Chemical Stability: Stable under normal handling and storage conditions
Reactivity: Not reactive under standard conditions; molten product may react with strong oxidizers or acids
Hazardous Reactions: None under ambient conditions
Hazardous Decomposition Products: Ammonia, caprolactam vapors, carbon monoxide, nitrogen oxides, hydrocarbons on burning
Conditions to Avoid: High temperatures, open flames, strong acids or oxidizers; avoid moist storage to prevent hydrolysis
Acute Oral Toxicity: Low toxicity, ingestion is not expected in industrial use
Acute Inhalation Toxicity: Mechanical respiratory irritation from dust; thermal decomposition gases may cause headache or nausea
Dermal Toxicity: Not absorbed in significant amounts; molten contact can cause severe burns
Chronic Toxicity: No evidence of carcinogenicity, mutagenicity, or reproductive toxicity from typical exposures
Irritation/Sensitization: Dust or powder may cause mild eye or skin irritation; not a skin sensitizer
Relevant Data: No significant health effects observed below decomposition temperatures in industrial and laboratory studies
Aquatic Toxicity: Not acutely toxic to aquatic organisms
Persistence/Degradability: Solid polymer is slow to degrade; does not bioaccumulate
Mobility in Soil: Pellets or fibers remain on soil surface and degrade slowly
Other Ecological Effects: Large spillage can cause physical hazards in water bodies (e.g., blockage, ingestion by wildlife)
Environmental Precautions: Prevent uncontrolled discharge into drains, ground, or surface waters
Recovery: Scrap resin may be recycled or reprocessed if uncontaminated
Disposal Methods: Dispose in accordance with local, national, or regional regulations; landfill or authorized incineration
Precautions: Avoid dust formation during handling, do not discharge into sewage
Container Disposal: Empty packaging should be recycled or disposed of safely; remove all product residues before discarding
UN Number: Not regulated
UN Proper Shipping Name: Not classified as hazardous
Transport Hazard Class: None
Packing Group: None
Environmental Hazards: Not classified as environmentally hazardous for transport
Special Precautions: Secure packaging to avoid spillage, prevent dust emissions in bulk shipments
US Regulatory Status: TSCA inventory listed; not subject to OSHA hazard communication standard for solid
EU Information: REACH registration completed for polymers; not classified as hazardous
Other Global Regulations: Listed in the relevant chemical inventories for Japan, Australia, Canada, China, Korea
Labeling: No mandatory hazard labeling for shipping or handling solid, finished material
Restrictions: Ensure compliance with food contact or medical application standards if relevant for end use
