Hazard Classification: Classified as non-hazardous under normal use, but processing like cutting, grinding, or heating may generate dust or fumes
GHS Label Elements: No pictogram required, but caution for molten or heated material
Route of Exposure: Eyes, skin contact with fibers or fumes, inhalation of dust
Acute Symptoms: Itching, mild mechanical irritation from fibers; fume exposure from overheating can cause headaches or respiratory discomfort
Chronic Effects: No established chronic health effects for finished fiber; decomposition products present risks if inhaled
Polyethylene Terephthalate (CAS 25038-59-9): 80-95%
Phosphorus-Containing Flame Retardant (ex. Dimethylphosphonate or similar): 5-20%
Additives: Trace stabilizers, antimony compounds (catalyst residues, often < 0.05%)
Impurities: Extremely low, typically not exceeding 0.01%
Eye Contact: Flush continuously with water, remove any fibers from eyelashes, seek medical advice if irritation persists
Skin Contact: Wash with water and soap, remove contaminated clothing, access medical care if allergic reaction develops
Inhalation: Move to fresh air, keep airway clear if exposed to high concentrations of fiber dust or fumes
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical advice if significant amount is swallowed
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Hazardous Combustion Products: Irritating smoke, carbon monoxide, carbon dioxide, aromatic and aliphatic hydrocarbons, phosphorus oxides
Special Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Unusual Fire Hazards: Fiber melts, drips, may produce dense smoke before ignition
Personal Protection: Use goggles, gloves if handling large quantities of loose fiber or dust
Spill Response: Gather scattered material using mechanical means, minimize dust creation
Environmental Precautions: Avoid allowing fiber or dust to enter drains or waterways
Disposal: Collect in designated waste containers for further handling
Handling: Employ proper ventilation to control dust accumulation, avoid eating/drinking/smoking during handling, wash hands after use
Storage Conditions: Store indoors, away from heat and direct sunlight, keep containers closed, maintain low humidity
Incompatible Materials: Strong oxidizers, strong acids, strong bases
Engineering Controls: Local exhaust ventilation for handling fiber dust or processing fumes
Exposure Guidelines: No specific OSHA PEL for polyester, but keep airborne particulate below nuisance dust limits (e.g., 10 mg/m³ total dust)
Personal Protective Equipment: Safety glasses, gloves, dust mask or respirator during heavy dust or thermal processing
Hygiene Measures: Wash thoroughly after fiber contact, do not touch eyes or mouth
Appearance: White or slightly colored fiber, filament, or staple
Odor: Odorless in solid form
Melting Point: 255–265°C
Boiling Point: Not applicable
Flash Point: Above 400°C
Solubility: Insoluble in water, soluble in some chlorinated aromatic solvents at high temperatures
Density: 1.36–1.40 g/cm³
pH: Not applicable
Vapor Pressure: Negligible
Explosive Properties: Not explosive
Other Data: May yellow upon overheating over 200°C
Chemical Stability: Stable under normal conditions
Conditions to Avoid: Prolonged heat over melting point, strong oxidizers, open flames
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, phosphorus oxides, soot, various hydrocarbons
Incompatibility: Strong acids and bases degrade fibers and release gases
Acute Toxicity: Generally considered low for finished fiber; not acutely toxic via oral/dermal/respiratory routes
Skin Corrosion/Irritation: Mechanical irritation possible from fiber ends
Eye Damage/Irritation: Mild irritation possible; dust/fiber in eyes causes redness or itching
Respiratory Sensitization: Minimal, but high fiber dust may trigger discomfort in sensitive individuals
Chronic Exposure: No known carcinogenic, mutagenic, or reproductive hazards; antimony compounds potentially toxic above certain exposures, but fiber-bound residues considered low risk by current standards
OSHA/IARC/ACGIH Listing: Not listed as hazardous or carcinogenic
Aquatic Toxicity: Finished fibers do not dissolve; small fragments may pose physical hazards to aquatic life
Persistence and Degradability: Polyester resists biological degradation, persists in environment under ambient conditions
Bioaccumulation: No significant bioaccumulation expected
Mobility in Soil: Pellets/fibers remain on surface unless physically transported or buried
Other Adverse Effects: Microplastic pollution potential; strict control of fiber loss recommended
Waste Treatment Methods: Mechanical recycling where facilities exist, incineration with proper air filtration, landfill as last resort
Special Precautions: Avoid burning in open air due to toxic combustion gases
Disposal Containers: Use labeled containers dedicated for synthetic material waste
UN Number: Not regulated
Proper Shipping Name: Polyester Flame Retardant Fiber
Transport Hazard Class: Not classified as hazardous
Packing Group: Not applicable
Environmental Risks: Avoid release to environment during transport by keeping bales wrapped and secure
Special Precautions: Keep away from heat, sparks, and open flame during shipping
OSHA Regulation: Not hazardous under normal conditions
TSCA Inventory: All ingredients listed
REACH Status: Fully compliant if manufactured/imported in the EU
Other National Regulations: Local implementations may vary, so check community right-to-know laws and regional environmental restrictions
Labelling Requirements: No hazard symbol required for finished goods; safety information provided on handling and fire safety
