ETFE PELLET
Ethylene-tetrafluoroethylene, also known as ETFE, is one of the strongest fluorine plastics with good mechanical properties, weather resistance, flame retardant, gas barrier properties and chemical resistance. In addition to the similar properties like other fluorine resins, it also shows good radiation resistance, strong adhesion with metal surface, and is lighter than other fluorinated materials.

Attention
1. When dealing with ETFE powder for deep processing, operators must wear protective cloth and mask to avoid potential safety hazards, such as inhalation of dust and toxic gas, or hurt by high temperature. No open flame and smoking in workplace. Exhaust devices should be installed.
2. When dealing with ETFE pellet for deep processing, operators must strictly control processing technic. Processing temperature should not be kept no more than 350℃. Wear protective cloth and mask to avoid potential safety hazards, such as inhalation of dust and toxic gas, or hurt by high temperature. The workplace should be tidy and ventilated.
3. Product waste must be handled properly following local laws and regulations.
Packaging, Transportation and Storage
1. Single-layer bag, 20Kg/bag.
2. The product should be stored in cool ventilated place and away from fire source and heat source. It should also be prevented against moisture and sunshine, kept in upright position and handled with great care.
3. Once opened, unused product should be repacked to avoid any dust or contamination.
