Application:
EHW90K is 90℃cracking resistant low-smoke halogen-free flame-retardant jacketing compound, which doesn’t contain any heavy metals like Pb,
Ba, Cd, Cr, Sn and Sb. The properties can meet RoHS Standard. It has excellent physical and mechanical properties, especially good thermal-shock
resistant performance. Its temperature resistant is from -40 ℃to 90℃and mainly used for communication cables, control cables and power cables,
which have strict cracking-resistant requirements.
Processing Indicator
Recommend to use special screw for low-smoke halogen-free compound with L/D=20-25.
