Application:
FEJ90, FEJ105, FEJ125 and FEJ150 are irradiation cross-linkable insulation compounds for wire and cables, which regards polyolefin resin
as the basic raw material, and adds anti-oxidant, cross-linkable agent and modified agents and other additives. They have excellent extruding
property and physical property and can be widely used for various control cables, instrument installment wires of automotive low-voltage wires,
and electrical wires. The highest working temperature is 90-150℃. Moreover, they don’t contain heavy mentals like Pb, Ba, Cd, Cr, Sn and Sb,
and all their properties can meet the requirements of ROHS Standard.
Processing Indicator
Recommend to use single-screw extruders with L/D= 20-25.
