Polyether Ether Ketone (PEEK) is a high-performance thermoplastic known for its excellent mechanical properties, chemical resistance, and thermal stability. Its MSDS typically includes the following key information:
Chemical Identity and Properties:
PEEK is identified as a semi-crystalline thermoplastic polymer composed of repeating units of ether and ketone groups. It has a high melting point (around 343°C), which contributes to its thermal stability under normal operating conditions.
Physical and Chemical Properties:
Appearance: PEEK is often described as a solid, typically in the form of pellets, powders, or molded parts.
Odor: Generally odorless.
Solubility: Insoluble in most common organic solvents but soluble in concentrated sulfuric acid and some aromatic hydrocarbons under certain conditions.
Hazards Identification:
PEEK is generally considered non-toxic and non-hazardous under normal handling and use conditions.
However, like any high-temperature polymer, processing or machining operations may generate dust or fumes that could irritate the respiratory system. Proper ventilation and personal protective equipment (PPE) should be used when handling PEEK in these situations.
Handling and Storage:
PEEK should be stored in a cool, dry place away from direct sunlight and sources of heat.
It should be handled in well-ventilated areas to minimize exposure to decomposition products at high temperatures.
Avoid prolonged or repeated skin contact. Use gloves and safety glasses when handling molten PEEK or during machining operations.
Fire and Explosion Data:
PEEK is typically non-flammable and does not readily support combustion.
However, decomposition at high temperatures can release gases and vapors that may be flammable.
First Aid Measures:
In case of skin contact, wash affected area with soap and water.
In case of eye contact, rinse eyes thoroughly with water for several minutes and seek medical attention if irritation persists.
If PEEK is ingested accidentally, seek medical attention immediately.
Ecological Information:
PEEK is not considered environmentally hazardous. Proper disposal methods should be followed to minimize environmental impact.
Disposal Considerations:
Dispose of PEEK waste according to local regulations. Incineration in a controlled environment is typically recommended.
In conclusion, the MSDS for Polyether Ether Ketone (PEEK) provides essential information to ensure safe handling and use of this high-performance polymer, emphasizing its chemical stability and minimal hazards under normal conditions while outlining proper safety measures for potential exposures and emergencies.
