Overview of PPA manufacturer's explanation of PPA risk
According to the United Nations GHS classification standard, this product is non hazardous.
The results showed that 20.38% of the components had unknown harm to the aquatic environment.
First aid measures
Eye contact: immediately flush eyes with plenty of water for at least 15 minutes. Do not remove the hot melt. See a doctor immediately.
Skin contact: wash the affected area with soap and water. Do not remove the hot melt. Cover the affected area with a clean cloth. Seek medical advice immediately
Inhalation: remove the patient to fresh air. If symptoms worsen, seek medical treatment.
Ingestion: no need for first aid. If symptoms / symptoms worsen, seek medical attention immediately.
Fire fighting measures
Suitable extinguishing agent:
Contact hazard during combustion: this material will not burn. Contact with extreme heat can cause thermal decomposition. Avoid raising the dust, reduce dust ignition or explosion, and there is the risk of electrostatic ignition during operation and use. The product should be properly grounded in accordance with the method described in nfpa77
Fire fighting procedures: wear a full set of protective equipment (Bunker Gear) and self provided breathing apparatus (SCBA).
Special guidance for fire protection: dust cloud of this material may explode when encountering fire source.
Performance description: the hot deformation temperature of modified poly (p-phenylenediamine) (PPA) plastics is up to 300 ℃ and 170 ℃ continuously, which can meet the short-term and long-term thermal properties you need. It can maintain its superior mechanical properties strength, hardness, fatigue resistance and creep resistance in a wide temperature range and high humidity environment. Toughened Lu grade PPA combines superior toughness with a certain range of hardness and flexibility, which requires disposable rigidity in fasteners and good flexibility in repeated use. At the same time, special grade products are provided for application on the surface that can be sprayed and electroplated, and the application of fire resistance, glycol resistance and reflexivity requirements
