四氟包覆EPDM垫夹水线 (ASME B16.20)
When PTFE layers heated, the PTFE layers would bonded
with EPDM rubber, then this kind of gaskets have the good
advantages of both PTFE and EPDM, has good corrosion resistance
of PTFE, and also has good elasticity of EPDM.
PTFE bonded EPDM gaskets are suitable for PVC pipes, and enameling pipes
use for sealing function.
We can make the PTFE bonded EPDM gaskets in standards of:
ANSI/ASME B16.5 CLASS 150
JIS10K
DIN 2501 PN10
DIN 2501 PN16
SABS1123 1000/3
-
EPDM - durometer A, hardness 65 - 68
-
PTFE bonded EPDM for maximum corrosion resistance
-
Perfect sealing at low bolt tightening torque ratings; longer gasket life
-
Ideal for plastic piping systems, as well as metal or plastic-lined metal systems
-
Working temperature:
-
EPDM: - 40 - 195F
-
PTFE-bonded: - 40 - 250F
