CLAMPABLE, RECYCLABLE THERMOPLASTIC FUEL TUBING FOR LOW-PRESSURE APPLICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240017517 titled 'CLAMPABLE, RECYCLABLE THERMOPLASTIC FUEL TUBING FOR LOW-PRESSURE APPLICATIONS

Simplified Explanation

The patent application describes a multilayered tubing for low-pressure fuel applications. The tubing consists of a first thermoplastic layer that defines an interior cavity and a second thermoplastic layer that encases the first layer. The first layer is made of an extrudable thermoplastic fluoropolymer, while the second layer may include a semi-crystalline thermoplastic polymer. In some variations, an adhesive is placed between the first and second layers. In other variations, a third thermoplastic layer is added between the first and second layers, with a first adhesive between the first and third layers and/or a second adhesive between the third and second layers.

  • The patent application describes a multilayered tubing for low-pressure fuel applications.
  • The tubing includes a first thermoplastic layer that defines an interior cavity and a second thermoplastic layer that encases the first layer.
  • The first layer is made of an extrudable thermoplastic fluoropolymer.
  • The second layer may include a semi-crystalline thermoplastic polymer.
  • An adhesive can be placed between the first and second layers.
  • In some variations, a third thermoplastic layer is added between the first and second layers.
  • A first adhesive can be placed between the first and third layers, and/or a second adhesive can be placed between the third and second layers.

Potential applications of this technology:

  • Low-pressure fuel systems in automotive vehicles
  • Fuel delivery systems in aircraft
  • Fuel transfer systems in marine vessels

Problems solved by this technology:

  • Enhanced durability and resistance to fuel degradation
  • Improved flexibility and ease of installation
  • Reduced risk of fuel leakage

Benefits of this technology:

  • Increased safety and reliability in fuel applications
  • Extended lifespan of fuel tubing
  • Cost-effective solution for low-pressure fuel systems


Original Abstract Submitted

a multilayered tubing for low-pressure fuel applications is provided. the multilayered tubing includes a first thermoplastic layer defining an interior cavity and a second thermoplastic layer encasing the first thermoplastic layer. the first thermoplastic layer includes an extrudable thermoplastic fluoropolymer, and the second thermoplastic layer may include a semi-crystalline thermoplastic polymer. in certain variations, an adhesive is disposed between the first thermoplastic layer and the second thermoplastic layer. in still other variations, a third thermoplastic layer is disposed between the first thermoplastic layer and the second thermoplastic layer. in such instances, a first adhesive can be disposed between the first thermoplastic layer and the third thermoplastic layer and/or a second adhesive can be disposed between the third thermoplastic layer and the second thermoplastic layer.
