Why TPRR®

New possibilities. Over and over again.

The secret behind TPRR® is a unique and patented method that – highly simplified – works like this:

  1. Discarded image tires are collected. We use all kind of tires, and for the TPRR® method the vulcanisation actually ensures that the end product is as good or better than a material that would use virgin rubber as the base.
  2. The tires are cut into smaller pieces and the rubber is separated from the metal and the fabric. The rubber is then grounded into a powder and mixed with different kinds of recycled plastic.
  3. The bond between the rubber and the plastic is reinforced with a special kind of copolymer molecule. Depending on the hardness of the material, and the desired properties of the finished materiel, the recipe is varied and mixed with different types of fibers for additional strength.
  4. The result is called TPRR® a category of materials that all are based on thermoplastic recycled rubber. The mixture can then be formed in a variety of ways, from rolling or punching to advanced extrusion or injection technics
  5. The new materials can be recycled over and over again, making both the production and the life-cycle of the end products very environmental friendly.

(Left) This picture shows that the bond between the rubber particles and the plastics are so strong that the rubber particles are cut in half. If the bond would not be so strong the particles would have dug pits! (Right) EcoRub will have a fully equipped laboratory to be able to test and produce a wide range of materials.

 

What characteristics are you looking for?

Since the TPRR® provides a mix of preferred features of both rubber and plastics, the material is highly customisable. There is almost no limit to what characteristics your TRPP material can have. Are you looking for a highly shockproof or extremely durable solution? Or would your end product rather be easily biodegradable in order to minimise unwanted nature impact? Do you need a material that withstands UV radiation or something that is resistant to fungi and bacteria? There is a TPRR® solution available. Or are you interested of your own recipe that creates material features that the world have never seen. We help you all the way.

A new material category. And the solution to a growing problem

Vulcanization has one dramatic side effect: It changes the rubber material structure in a way that is virually irreversible, which means that the material is virtually impossible to recycle.

In Europe, 300 million used car and truck tires are disposed each year, and in the US the figure is just as high. Since there has been no way to reverse the vulcanization the, countries and companies try other ways to stop the tyre mountain to grow: As land fill, as granules for play and sports areas, as  combustible substance for energy, etc etc. Or simply nothing and just watch the mountain grow (or export the problem to another country).

Up until now, that is.

Best of both worlds…

With Ecorub’s patented method, vulcanized rubber is no longer a problem. We have discovered a way to reverse the irreversable molecule structure of the vulcanized rubber. By mixing the recycled rubber with a special copolymer, different kinds of recycled consumer plastics and biological fibres or microbes we are able to create a thermoplastic rubber that enables a whole range of new desirable features and totally eliminates the problems that normally are associated with rubber and plastic combinations. We call this new category of material TPRR® – thermoplastic recycled rubber)

TPRR® materials can be formed/extruded in the same ways as a thermoplastic – even using the same equipment. The end product also inherits the same desirable characteristics one would find in rubber materials, such as:

WELDABLE

The material is weldable. This means the fabrics we manufacture can be welded together to larger areas, without any risk that the material will burst in the joint. For example, it is good solution if you want a large fluid barrier over a surface under a pond or a landfill.

UV RESISTANT

The material is resistant to UV light. The rubber particles contained in the material are enclosed in plastic, making the material more UV-cured than virgin rubber. It may be good if you intend to use the material for outdoor purposes.

CONFORMABLE

The TPRR® behaves like a thermoplastic. Because the material is not vulcanized to gain its strength, it can be used in the same way as a thermoplastic in an extrusion process, or in other molding processes. This allows you to shape more complex forms and use the material to a wide variety of components.

SHOCK ABSORBENT

Although TPRR® are very durable, it also retains the properties of the natural rubber, making it extremely shock absorbent and suitable for vibration reductions. The material regains its shape ever after very rough treatment. This makes it perfect for details in harsh or exposed environments

…and for the next generation

Adding to all these features is the fact that TPRR® as its name implies, is fully recyclable. Not one, not twice but over and over again. We are even able to re-separate the different components of the TPRR® if needed, making it a perfect choice for products that want to combine superior material characteristics with environmental sustainability. TPRR® is truly a material for the circular economy.
