1. Hazard Identification
Substance Classification: Non-hazardous under normal handling conditions.
Labeling Requirement: Not required.
Overexposure Effects:
-
Normal handling: No significant hazard.
-
Machining or high-temperature processing: May generate dust and toxic vapors. Exposure to PTFE decomposition products or copper fumes can cause Polymer Fume Fever, characterized by flu-like symptoms including fever, chills, and muscle aches, typically lasting ~24 hours.
Routes of Exposure:
-
Inhalation: Dust may irritate respiratory tract. Vapors from decomposition or copper fumes may cause temporary flu-like symptoms.
-
Skin Contact: Dust may cause mechanical irritation.
-
Eye Contact: Dust may cause mechanical irritation.
-
Ingestion: Not expected under normal use.
-
Chronic Effects: Glass microfiber is classified by IARC as Group 2B (possibly carcinogenic to humans).
2. Composition / Ingredient Information
| Component | CAS No. | EINECS | Typical Exposure Limits | EU Classification | Notes |
|---|---|---|---|---|---|
| Glass Microfiber (encapsulated) | 65997-17-3 | 266-046-0 | 5 mg/m³ (respirable dust) | Not classified | Encapsulated in PTFE, low hazard |
| Titanium Dioxide | 13463-67-7 | 236-675-5 | 15 mg/m³ (total dust) | Not classified | Common filler, low hazard |
| Copper | 7440-50-8 | 231-159-6 | 1 mg/m³ (dust & mist) | Not classified | Trace element, machining hazard only |
| Aluminum | 7429-90-5 | 231-072-3 | 5 mg/m³ (respirable), 1 mg/m³ (dust & mist) | Not classified | Only aluminum powder is hazardous |
Note: The material is considered an “article” under 20 CFR 1910.1200 and REACH (EU Regulation 1907/2006), and does not release hazardous chemicals under normal use. No formal chemical safety datasheet is required.
3. First Aid Measures
-
Inhalation (dust or fumes): Move victim to fresh air. Seek medical attention if symptoms persist.
-
Eye Contact (dust): Rinse with plenty of water for 15–20 minutes. Do not rub. Seek medical attention if irritation persists.
-
Skin Contact (dust): Remove contaminated clothing. Wash affected area with water for 15–20 minutes. Seek medical attention if symptoms persist.
-
Ingestion: Unlikely. Seek medical attention if accidental ingestion occurs.
4. Firefighting Measures
-
Flash Point / Autoignition Temperature: Not established.
-
Extinguishing Media: Water spray, foam, CO₂, dry chemical powder.
-
Special Firefighting Instructions:
-
Decomposition during fire may produce toxic fumes.
-
Firefighters should use self-contained breathing apparatus and full protective clothing.
-
-
Fire & Explosion Hazards: None known.
5. Accidental Release Measures
-
Personal Precautions: Avoid inhalation of dust; wear proper PPE; eliminate ignition sources; avoid contact with skin and eyes.
-
Environmental Precautions: Prevent release into drains, surface water, or soil.
-
Cleanup Methods: Sweep or scoop material into appropriate containers for disposal. Avoid generating dust.
6. Handling and Storage
-
Handling: Wear appropriate personal protective equipment (PPE) as described in Section 8. Avoid dust inhalation.
-
Storage: Store in a cool, dry, well-ventilated area, away from ignition sources. Keep containers tightly closed.
7. Key Safety Highlights for Engineers and Manufacturers
-
Non-Hazardous in Normal Use: Safe for handling in PCB manufacturing and assembly.
-
Machining Considerations: Use dust extraction and protective equipment when milling or drilling to avoid respiratory irritation.
-
Thermal Safety: Avoid exceeding decomposition temperatures to prevent toxic vapors.
-
Long-Term Reliability: Glass microfiber and PTFE composition provide excellent mechanical, thermal, and moisture stability.
-
Compliance: Conforms to OSHA, REACH, and EU safety regulations.
