Optimal Pipes, Tubes and HosesSealingsLubricationHigh-Temperature ComponentsMulti-Layer Extrusion
Polidan® PEX is used for small diameter pipes to transport fluids inside the vehicle.
Key features:
- Excellent temperature resistance (operating temperature range: -40°C up to 110°C)
- High environmental stress crack (ESCR) and notch resistance
- Good chemical resistance
- Good abrasion and Rapid Crack Propagation resistance
Algoflon® DF powders are used for pipes and tubings for fuel transport in automotive systems with exceptional performance:
- Chemical inertness in aggressive environments
- Thermal resistance
- Electrical properties
- Non-stick characteristics in a wide range of temperatures from cryogenic to 260°C
Solef® PVDF qualities of impermeability and chemical resistance recommend their use in automotive fuel transport systems. A layer of Solef® PVDF within the construction of a multi-layer fuel line enhances the strength, permeation resistance and durability of the hose.

- Ultra-low permeation
- Bio-diesel and flex fuel compatibility
- Long-term fuel contact from 60-125°C
- Continuous use from 120-180°C
- Resistance to automotive fluids,
- cleaners and road salts
- ESD and toughened grades available
Typical Applications
- Fuel flanges
- Rollover valves
- Quick connects
- Filter housings
- Fuel rails
- Sender units
- Fuel and vapor lines
- Throttle bodies
- Carburetors
Materials
Amodel PPA Fuel Compatability The compatibility of Amodel PPA with many current and potential future fuel blends was evaluated in extensive laboratory testing. This included exposure to bio-diesel, diesel, and diesel with aggressive water for 6,000 hours at 125°C (to simulate under-the-hood conditions) and exposure to fuel C, flex fuels, and auto-oxidized fuels for 5,000 hours at 60°C (to simulate fuel tank conditions).
Amodel PPA showed low weight gain, little dimensional change, and excellent retention of mechanical properties over the range of fuels and temperatures evaluated. Please contact your Solvay representative for detailed test results. Average Permeability Rates Over 28 DaysChemical Compatibility

Ixef® PARA Reduces Complexity and Cost with Fewer Layers
Ixef BXT-2000/0203 has been approved by the California Air Resources Board (CARB) and the U.S. Environmental Protection Agency (EPA) as a barrier solution for three-layer fuel tank systems for small-engine fuel tanks such as lawnmowers, snow blowers, weed trimmers and generators.
 Ixef BXT-2000/0203 is a reformulated extrusion and blow moldable polyarylamide (PARA) resin that offers a lower processing temperature, higher flow and a wider processing window than the previous BXT 2000 grade.
The material can also be used in two-layer barrier structures such as fuel lines, filler pipes and low-permeation fuel hoses because it can withstand direct contact with fuel.
Key Features
- Ultra-low permeation
- Excellent impact resistance to minus 40°C
- Direct contact with bio-diesel and high ethanol fuels
- Two-layer and three-layer barrier technology
- Exceptional processing stability
- Continuous barrier at pinch line
- Low extractibles in alcohol-based fuels
Typical Applications
- Small engine fuel tanks
- Delivery and vapor hoses
- Filler tubes
- Storage containers
- Sheet and film
Permeability
When exposed to CM15 fuel for 5,000 hours at 60°C, Ixef BXT 2000 showed low weight gain, little dimensional change and excellent retention of mechanical properties. Additional testing to confirm the material’s long-term compatibility with Fuel C, CE10, CE85, B20 SME, B20 RME and No. 2 diesel are near completion.
