ETFE Pellet for Molding SF-4026 with MFR 16.1-20
Product Description
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. Double-layered polyethylene sealed and then packed in carton.
10Kg/bag, 20Kg/carton.
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
