Why use NGR?

  • NGR closely matches natural & synthetic rubber characteristics.
  • NGR is much cheaper than virgin rubber.
  • NGR can replace natural & synthetic rubber (up to 70%), and, partially carbon black without loss of quality.
  • Much higher added value & significant cost savings for your products.
  • NGR is more effective & cheaper than world’s other similar solutions.
  • NGR is simple in production. The whole process is mechanical-chemical reaction and carried out at room temperature.
  • NGR is 100% environmentally safe. No dangerous chemicals are used and no hazardous emissions during production.
  • NGR is tested and proven by world’s leading laboratories.
  • NGR production and all related technologies are patented and certified under ISO 9001:2008.

How NGR is made?

NGR rubber is extracted (devulcanized) from pre-selected end-of-life car or truck tires.

The tire / truck rubber is devulcanized, the sulphur cross links in the polymer chain uncoupled, but its chemical composition is not changed.

Vulcanised Rubber

Devulcanised Rubber

Mechano-chemical treatment also creates highly developed surface of NGR that increases its interaction with virgin rubber.

Vulcanised Rubber (Source)

NGR (Devulcanised)

NGR production and devulcanisation is based on mechano-chemical processes using our Next Generation Devulcanizer which is now patented. 

The process is a mechanochemical reaction by nature, is such that it requires mechanical shear to expose fresh crumb surfaces so that the modifier reactant can effectively uncouple the sulphur cross links in the polymer chain.

Applied devulcanization process is based on the recognized effectiveness of several chemical reactions: free radical R• , organic cations R+ and acid / base A+ / B-.

The synergy between these reactions and tribologic effects in mechanical shear devices leads to the degree of devulcanization above 80% as determined by ASTM D 6814 standard.

The special equipment and technology allow us to obtain clean rubber crumb as an end product which does not contain any textile or steel wire.

In order to effectively uncouple the sulphur cross links in the polymer chain, the crumbs are going through  mechano-chemical reaction with our patented devulcanizer.

Following the mechano-chemical reaction  the obtained rubber can be re-used in manufacturing of PRODUCTS OF HIGH QUALITY RUBBER without degrading any of its properties.

We are Green

Next Generation Rubber: an innovative solution with environmental and business sense

Rubber Products LTD is focused on reduction of discrepancy between high growth in demand of rubber, low production from recycling industry and high volumes of accumulated rubber waste.

The increased demand in rubber tires results in the growth of waste rubber and stockpiles around the globe:

  • Total amount of rubber recycled at its end-of-life:3−15%
  • Amount of waste rubber re-used in some way (e.g.,retreading, new products and so on): 5−23%
  • Amount of waste rubber consumed for energy recovery:25−60%
  • Amount of waste rubber sent to landfill or stockpiled:20−30%

Next Generation Rubber technology helps to:

  • Recycle the world’s stock of rubber & tire waste
  • Reuse recycled rubber in production of new products without sacrificing quality
  • Reduce world consumption of oil and rubber trees

Partnership & Cooperation

Licensing and transfer of know-how is a short cut to producing high quality rubber products and lower costs:

Opportunity for Licensing

  • The license to use NGR ® technology for de-vulcanization of waste rubber and production of NGR ® products.
  • Turn-key construction of the production plant for the Licensees with all necessary equipment.
  • Necessary quantity of NGD® de-vulcanizer for production of NGR ® products.
  • Territorial exclusivity in selected regions.
  • Staff training and continuous consultation.
Tailored Solution

Required investment depend on individual specifications of the licensee and initial assessment of needs i.e. production capacity, geographical exclusivity, level of automatisation of the plant etc.

Availability of financing

Launching a plant with NGR® technology is an eco-friendly project which in some countries is subsidies by the government and additional financing is available through various programs, including from EC.

Required Investments

Exact calculation of required investments and overall costs is provided to potential licensees on demand.

Expected result

  • Modern, environmentally friendly and highly automated Next Generation Rubber production plant.
  • Significant cost saving in production of rubber compounds or end rubber products through use of NGR ® technology, including NGD ® de-vulcanizer.
  • Increased flexibility in production of high-quality rubber end products and overall competitiveness in rubber industry.
  • Decrease in business risk for companies in the rubber industry by eliminating the dependency on oil (used to produce synthetic rubber) and saving rubber trees (needed for extraction of natural rubber).
  • Quick return on investments. Estimated ROI time – 2,5 years
