  • Water: max. water absorption: 0 %, up to +250°C resistant

  • Fire behavior: Oxygen index (LOI): 90 %, classification: V-0 (UL94)

ADVANTAGES

The advantages of ZX-550 over PTFE (polytetrafluoroethylene, teflon, ftoroplast-4):

​

  • 1000% higher wear resistance

  • Higher stiffness and hardness

  • The modulus of elasticity in flexture is 30% higher.

  • Lower expansion and wear coefficient

  • Improved pv-value
