Application:
TEWR960 is a kind of thermoplastic low-smoke halogen-free flame-retardant jacketing compounds. It has good mechanical property,
high-temperature resistant and processability, especially good irradiation-resistant and aging resistant properties. It is low-smoke and
halogen-free, especially suitable for the jacketing which has strict aging property requirements. It is also suitable for the jacketing of K1,
K3 nulcear power cables. According to The Arrhenius Equation, this product can reach 90℃and 60-year service life.
Processing Indicator
Recommend to use special screw for low-smoke halogen-free compound with L/D=20-25.
