AFLAS® FEPM Lamination Technology Enables Multilayer Hose Constructions to Withstand Harsh Automotive Conditions

EXTON, Pa., February 28, 2020 – AFLAS^® FEPM fluoroelastomer lamination technology for multilayer automotive hose constructions is ideal for use in high-pressure, high-temperature areas near the engine, where they are also exposed to NOx, SOx, engine oils or other aggressive automotive fluids.  AGC Chemicals Americas will feature AFLAS at the ITB Automotive Energy Storage Systems Conference, March 4-5 in Novi, Michigan.

AFLAS FEPM fluoroelastomers can withstand continuous service temperatures up to 200 °C and have excellent acid, base, amine and steam resistance. This new FEPM material can be laminated directly to dissimilar elastomers, without the need for a tie-layer or adhesive, to achieve a peel strength in excess of 7 N/in at elevated operating temperatures.

AGC also will feature the following materials that are designed to improve the performance of fuel system components like tanks, seals, vapor lines, hoses, tubes, cabling, as well as under-the-hood components for HVAC, evaporative emission control (EVAP), exhaust and coolant systems.

AFLAS Fluoroelastomers

• These fluoroelastomers enhance performance and extend the life of pumps and seals because they are highly resistant to acids, strong bases, solvents, hydrocarbons, amines and coolants commonly found in lubricating and extended-life fluids.
• AFLAS is used in seals found in EVAP systems that capture evaporating gasoline fumes and other emissions. These resins can also withstand nitrogen oxide reduction agents used in diesel engines equipped with selective catalytic reduction (SCR) technology.
• AFLAS fluoroelastomers exhibit superior electrical, chemical and thermal resistance, making them ideal for transmission cable and HEV/EV cable insulations that need to be lightweight and perform reliably at high temperatures.

Fluon ETFE Resins and Compounds

• Components such as liquid and vapor fuel lines, coolant tubes, compressor hoses, fuel tanks and filler necks exhibit outstanding performance in any construction when they are made from adhesive Fluon ETFE resins.
• High-temperature Fluon ETFE is an ideal material for automotive wire and cable insulation.
• Low-melting adhesive Fluon ETFE is a cost-effective solution in applications such as hot water hoses, rubber hose mandrels and multilayer tubes that convey harsh materials.

Fluon+ PTFE Compounds

• Fluon-filled PTFE compounds are used in seal and gasket applications that need to withstand ongoing heat and pressure, like fuel tanks, connectors and oxygen sensors for fuel systems.
