Sistema universal resistente a perforaciones para neumáticos y contenedores flexibles


Oferta Tecnológica
Un clúster francés especializado en caucho y polímeros, que ofrece asistencia a pequeñas y medianas empresas para aumentar sus niveles de innovación y empleo, ha desarrollado y obtenido la patente de un sistema eficiente resistente a perforaciones para neumáticos de cualquier tamaño y otros contenedores flexibles, como barcos neumáticos, tanques flexibles y aplicaciones civiles y militares. El principal componente es una membrana textil que previene fugas de fluidos, como gases y líquidos, en caso de cortes y perforaciones en contenedores flexibles. Se buscan empresas interesadas en establecer acuerdos de fabricación y licencia de la patente.


French universal perforation-resistant system for tyres and flexible enclosures offered for licensing
A French innovative cluster has patented an efficient perforation-resistant system for all sizes of pneumatic tyres and other flexible enclosures such as pneumatic boats, flexible tanks for civil and/or military applications.
The cluster is seeking companies interested in a partnership for manufacturing and licensing patents.
The French cluster is specialized in rubber and polymers sectors.
It supports small and medium size companies, to increase their levels of innovation and employment. This cluster covers four regions and 70% of French employees in the rubber sector. This cluster is a member of the European Tire and Rubber Manufacturers´ Association with the aim of developing innovation partnership.

This technology is a new and universal puncture-resistant system. Its main component is a coated textile membrane which prevents any leakage of fluids materials such as gases or liquids in the event of perforations or cuts of the flexible enclosures e.g. every kinds and sizes of tyres and/or flexible containers.
This puncture-resistant system works thanks to:
- An airtight and flexible perforation-resistant membrane attached to the remote edges of the tyre tread by means of airtight adhesives or by any other molding process and which is able to move easily laterally and vertically along the inside of the enclosure even under a force of pressure.
- A greater meridian length than that of the flexible enclosure.
- Such a membrane is made of a perforation-resistant woven or non-woven fabric thanks to its high tenacity fibers materials and coated with airtight flexible polymers.
- A layer of ultra-light pressure-resistant lubricated micro spheres or non-adherent materials such as, but not only, PTFE, PU, dry lubricant (graphite).
The French cluster is looking for industrial partnership for manufacturing, marketing and licensing.
Advantages and Innovations:
This system offers many advantages unlike the existing solutions in the market such as puncture-repairs sprays, run-flat tyres technology, plugs, and so on.
- It prevents any loss of pressure should deep punctures of the tread (up to 7/8 cm - 3 inches), or large cuts of the sidewalls of the tires (up to 5 to 7 cm - 2 to 3 inches) occur. Therefore, in case of punctures it ensures a much safer car driving. For instance it allows the driver not to have to change his driving conditions such as the modification of the speed and no stop at all is even required. Thus it allows the driver, should a puncture or a cut of the sidewall occur, to retain his original speed contrary to the run-flat technology and the current products. Also it is adjustable to all sizes of conventional tires either new or used.
- This system fits all sizes of conventional tyres either used or new.
- It can be fitted on all vehicles and therefore it is intended for sale on the after-market
- It provides a complete protection against all kinds of perforations.
- It does not modify the comfort of the vehicles and does not need any modification of their suspension like the run-flat technology needs.
- It does not need any special device for its fitting.
- It allows the suppression of the spare wheel without risks.
- It ensures a much safer driving because it avoids any change in the driving conditions against severe punctures (up to 7/8 cm - 3 inches) or cuts (up to 5 to 7 cm - 2 to 3 inches).
