BASE TYPE
ZX-550
Replace ceramic and PTFE sliding units
ZX-550 (PTFE) - is a thermoplastic synthetic composite material.
FEATURES
-

-
Hydrolysis resistance
-
Weathering resistant
-
No water absorption
-
Good machinability
-
Bondable
-
Chemical resistance to organic solvents and chemicals, petroleum products
CHARACTERISTICS
-
Working temperature: -250°C to +240°C (+260°C)
-
Surface pressure (p): max. 8 (12) MPa
-
Sliding speed (v): max. 250 m/min
-
Fatigue (S): tensile fatigue strength at 20 °C and 1E06 stress cycles, 1 Hz = 7 MPa
-
UV-radiation: resistant (1000 hours Xenon DIN 53597). Gamma-radiation: Limit absorbed dose 50 kGy
-
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
