Product Name: Polybutylene Terephthalate Chemical Formula: (C12H12O4)n Synonyms: PBT, Thermoplastic Polyester Usage: Components for electrical, automotive, and consumer products Manufacturer Contact: Refer to product label for supplier details Emergency Contact: Local Poison Control Center or company emergency number
Physical State: Solid (pellets, granules) GHS Classification: Not classified as hazardous according to GHS Route of Exposure: Dust inhalation, eye contact, skin contact during processing Health Risks: Dust may irritate eyes and respiratory tract, molten polymer can cause severe burns Environmental Risks: Not readily biodegradable, potential harm if released in waterways
Chemical Identity: Polybutylene Terephthalate Polymer CAS Number: 24968-12-5 Ingredient Breakdown: Polybutylene Terephthalate (>90%), inert additives and colorants (<10%) by weight Impurities: No significant hazardous impurities identified under normal processing
Eye Contact: Rinse eyes with water for 15 minutes, keep eyelids apart, access medical attention if irritation persists Skin Contact (Solid): Wash with soap and water Skin Contact (Molten): Cool area immediately with water, do not peel polymer off skin, seek urgent medical help Inhalation: Move affected person to fresh air, seek help if breathing difficulties arise Ingestion: Rinse mouth, obtain medical advice if large amounts are swallowed
Extinguishing Methods: Use foam, dry chemical powder, carbon dioxide, water fog Hazards from Fire: Combustion may release hazardous vapors, including carbon monoxide, carbon dioxide, formaldehyde Protective Equipment: Firefighters need full protective gear and self-contained breathing equipment Special Considerations: Cool nearby containers with water to prevent heat damage, avoid inhaling fumes
Personal Protection: Wear safety goggles, gloves, and dust masks if handling spilled granules or dust Environmental Precautions: Prevent entry of spilled pellets or dust into drains or natural water systems Spill Cleanup: Sweep or vacuum up material, place in marked container for recycling or disposal, wash down residue avoiding excessive water flow
Handling Recommendations: Ensure adequate ventilation at workstation, use methods to control dust Storage Conditions: Store in dry, cool, well-ventilated area, keep bags or containers tightly sealed Incompatible Materials: Avoid contact with strong oxidizing agents Special Instructions: Disconnect sources of static electricity, store away from heat and moisture
Occupational Exposure Limits: No specific OSHA or ACGIH limits for PBT, control dust below nuisance threshold (typically 10 mg/m³ for total dust) Engineering Controls: Use local exhaust ventilation at process points, maintain good general room ventilation Personal Protective Equipment: Wear safety glasses, gloves, long sleeves, and use respiratory protection in dusty environments Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke during use, change contaminated clothing promptly
Appearance: White or off-white granular, pellet, or powder form Odor: Faint, aromatic or neutral Melting Point: 220-225°C Boiling Point: Not applicable Decomposition Temperature: Above 280°C (emits fumes) Solubility (Water): Insoluble Specific Gravity: 1.3 Flash Point: >400°C Vapor Pressure: Not relevant at workplace temperatures pH: Not relevant (solid polymer form) Other Properties: Stable under standard storage, low flammability in ambient conditions
Chemical Stability: Stable in ambient atmosphere and recommended storage Incompatibilities: Strong acids, alkalis, oxidizing materials Hazardous Decomposition: Fumes may contain carbon oxides, hydrocarbons, and trace formaldehyde on decomposition Polymerization Risk: None under normal conditions Reactivity: Negligible at room temperature
Acute Toxicity: Not acutely toxic in solid form by ingestion, inhalation, or dermal contact Chronic Effects: No evidence of carcinogenic, mutagenic, or reproductive effects under normal use Irritation: Dust and particles can irritate eyes, nose, and skin Thermal Decomposition: Vapors may cause headache, nausea, mucous membrane irritation Key Facts: Molten polymer presents burn risk, dust exposure should be minimized
Mobility: Sinks in water, pellets and dust can travel long distances if released Persistence: Resistant to natural biodegradation Bioaccumulation: Not expected to bioaccumulate significantly in aquatic life Aquatic Toxicity: Not acutely toxic to fish or invertebrates in typical use forms Other Environmental Issues: Risk of physical harm to wildlife if ingested or if entangled
Disposal Methods: Recycle whenever possible, incinerate in approved facility if recycling not possible Waste Classification: Non-hazardous solid waste by most regulations Container Disposal: Clean thoroughly, recycle or dispose of empty containers according to local policies Avoid: Open burning, uncontrolled landfill disposal, or release into waterways
UN Number: Not regulated as dangerous for transport Transport Hazard Class: Non-hazardous goods Packing Group: Not assigned Labeling Requirements: No special transport labeling required Other Transport Notes: Use clean, sealed transport; prevent cargo shifting, keep dry
OSHA Status: Not classified as hazardous under OSHA regulations for solid manufactured articles TSCA Inventory: Listed REACH Status: Polymer exempt from registration, specific monomers registered SARA Title III: Does not contain reportable quantities Other Requirements: Users should comply with local, state, and federal regulations concerning handling, recycling, and disposal
