AGC Chemicals Americas
Introduces AFLAS® FEPM
Lamination Technology
for Multilayer Automotive
Hose Constructions
AGC Chemicals Americas Inc. introduces
two new AFLAS FEPM (tetrafluoroethylene
propylene) grades for use in high-temperature,
high-pressure automotive engine areas. AFLAS
400E and AFLAS 600X can be laminated directly
to dissimilar elastomers without using a tie
layer or adhesive.
AFLAS 400E and 600X can withstand continuous
temperatures up to 200 °C and offer manufacturers
a superior alternative to traditional materials like
acrylic rubber, silicone rubber and FKM. Adding a
layer of AFLAS 400E or 600X to a hose construction
enables it to function reliably despite ongoing
exposure to engine oils, acids, bases and steam.
AFLAS 400E and 600X are ideal for automotive
hose applications including intercooler, blow-by,
turbocharger, oil cooler, oil return, positive crankcase
ventilation (PCV), exhaust gas recirculation (EGR),
charge air cooler (CAC), automatic transmission fluid
(ATF) and coolant.
AFLAS is typically used in the innermost layer of
the hose, covered with an intermediate like AEM,
ACM, VMQ, EPDM or FKM. The hose is then covered
by textile reinforcement and finally an outer cover.
These new grades are colorable and cure rapidly for
easier processing. Suggested processing methods
include extrusion and coiling iron core.
