2.1 Classification of the substance or mixture

This substance or mixture has no hazard classification under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). 2.2. Warning label items including precautionary statements: Warning Label Items Including Preventive Measures This product does not require a warning label. 2.3. Hazard and Risk Classification Criteria Not Included in the Classification Criteria, etc. Hazards and Risks

Potential health effects

Acute exposure When handling at high temperatures, contact with the product may cause severe burns. . Inhalation Inhalation of vapors from thermal decomposition Thermal decomposition at temperatures above 350°C may cause flu-like symptoms including fever and muscle aches (polymer heat). Materials thermally decomposed at high temperatures are irritating to the respiratory system. Potential for respiratory irritation (if dust is inhaled). Skin contact: Materials thermally decomposed at high temperatures are irritating to the skin. When it enters the eye: Risk of eye irritation. (Physical effects of dust) Substances thermally decomposed at high temperatures are irritating to the eye. Environmental impact: The polymer itself is non- biodegradable due to its inert structure. “ARKEMA 420 Rue d'Estienne d'Orves - 92705 - Colombes - FRANCE Safety Data Sheet Number: 005061-001 (Version 1.3) revision December 9, 2024 (Previous version July 9, 2024)

Other physicochemical hazards

In the presence of fire sources Dust may form explosive mixtures in air. Thermal decomposition produces toxic and corrosive substances. Decomposition products: See 3. Names and Content of Constituent Ingredients This product is a single substance. Chemical Substance Name Einecs number CAS Number POLYVINYLIDENE DIFLUORIDE (PVDF) 24937-79-9 1: For the proper loading name, refer to Chapter 14. 4. Emergency Response Procedures 4.1. Required Emergency Response Techniques: General Precautions: If exposed to hot product: Immediately take a shower. While showering, quickly remove all contaminated clothing. Rinse thoroughly with plenty of water. Inhalation: Inhalation of fumes from thermal decomposition: Move to fresh air. Even if no immediate problems occur, consult a physician. Inhalation of dust: If persistent problems occur: Consult a physician promptly. If it comes into contact with the skin: Wash with soap and water. If contact occurs with hot products: If contact occurs with molten material, immediately cool the skin with cold water. If absorption occurs, do not attempt to remove the product. Treat the affected area as for a burn. Seek medical attention. When it entered the eye: If contact occurs with hot products Immediately rinse thoroughly with water. Consult an ophthalmologist promptly. Dust Immediately and thoroughly rinse the affected eye with water. If eye irritation persists, seek medical advice. When taking: If you experience any problems: Consult your doctor. 4.2. The most important symptoms/effects of acute and delayed reactions: Hazardous/Dangerous Phrase: Additional emergency treatment is required if HF is released due to thermal decomposition of this product. 4.3. etc. Physician's Precautions: No relevant information available. 5. Emergency Procedures for Explosions and Fires 5.1. Appropriate (and Inappropriate) Digestive Aids: Fire extinguishing agents: Water spray, carbon dioxide (CO2), foam, dry chemical powder Inappropriate digestive aid: Large quantities of water spray and airborne fine dust can cause fire. Risk of dust explosion. 5.2. Specific hazards arising from chemical substances: Above 350 °C: Toxic corrosive substances are generated during pyrolysis, including hydrogen fluoride. In the presence of fire sources such as: Dust may form explosive mixtures in air. 5.3. Guidelines for Firefighters
