3. Composition/Information on Ingredients

Component	CAS	Percentage (%)
PTFE (Polytetrafluoroethylene)	9002-84-0	60–70
Fiberglass Reinforcement	Mixture	30–40

4. First Aid Measures

• Inhalation:
  • Move the person to fresh air.
  • Seek medical attention if symptoms such as coughing or difficulty breathing persist.
• Skin Contact:
  • Wash thoroughly with soap and water.
  • Seek medical attention if skin irritation occurs.
• Eye Contact:
  • Rinse eyes with plenty of water for at least 15 minutes.
  • Seek medical attention if irritation persists.
• Ingestion:
  • Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.

5. Fire Fighting Measures

• Suitable Extinguishing Media: CO₂, foam, or dry chemical powders.
• Specific Hazards:
  • At temperatures above 260°C, PTFE decomposes and releases toxic gases such as hydrofluoric acid (HF) and perfluoroisobutylene (PFIB).
• Protective Equipment: Wear self-contained breathing apparatus to avoid exposure to toxic gases.

6. Accidental Release Measures

• Personal Precautions:
  • Wear gloves, safety goggles, and a respiratory mask to avoid inhaling dust.
• Cleaning Methods:
  • Collect solid materials mechanically.
  • Clean dust using a damp cloth or a suitable extraction system.

7. Handling and Storage

Handling:

• Avoid exposure to high temperatures.
• Minimize dust generation and use extraction systems if necessary.

Storage:

• Store in a cool, dry, and well-ventilated area.
• Keep away from strong oxidizers.

8. Exposure Controls/Personal Protection

Parameter	Exposure Limit
Dust (Particulate Matter)	10 mg/m³ (TLV)
Hydrofluoric Acid (HF)	0.5 ppm (TLV)

• Respiratory Protection: Wear a dust mask during machining.
• Hand Protection: Wear chemical-resistant gloves.
• Eye Protection: Wear safety goggles.

9. Physical and Chemical Properties
