Our Products


Nowadays, there is one problem which is giving headache to the many part of the world particularly Europe and Middle East. In fact, this problem lies everywhere but has been handled to a great extent. The problem is pile of used truck & car tires. The reason why it’s been a problem in Europe and Middle East is because there is more use of radial tires. The radial tires are much difficult to recycle and hence been neglected. At the other end, a Bias Ply tire uses less steel wire and can be recycled easily due to high proportion of rubber used in it. Varun Polymers GmbH has especially focused and gives you edge over this limitation of recycling radial tires but we are also capable to process also any kind of vulcanized industrial rubber waste.

Rubber DeVulcanization Chemicals

We are manufacturer of rubber de-vulcanization chemicals and also traditional reclaiming agent which are continuously used in Reclaim Rubber Industries as per their unique and different types of manufacturing process & methods. We advice to our clients about the uses of these rubber reclaiming agent in their Rubber Reclamation plants according to their adopted methods and circumstances under which they are working.

AmR-NHRDe078Devulcanizing Catalyst

AmR-NHRDe078 has been developed during year 2012 / 2013 and is used in medium pressure methods like Rotary Autoclave method and getting pressure only up to 240PSI to 250PSI and temperature up to 221,8 Degree Celsius. Especially developed to process rubber crumb out of radial tire which are most popular in western hemisphere.


AmR-NHRDe078 is used as a catalyst in the process of making de-vulcanized rubber crumb. Any kind of rubber (vulcanized rubber scrap) whether synthetic rubber or natural rubber can be reclaimed (de-vulcanized) by the using this rubber reclaiming agent at unbeatable quality.


AmR-NHRDe078 makes the process of de-vulcanization of rubber faster that too at a lower temperature & therefore reduces power consumption of rubber processing plant, saves process timing, rubber can be de-vulcanized at a lower temperature, improve the efficiency of plant, saves the intake of fuel, improves the quality of resulting reclaim rubber and risk of hardening is reduced.

AmR-NHRMo054: Rubber Modifier

AmR-NHRMo054 is used to staple the de-vulcanized material at high quality level for longer storage. This modifier is used to reduce the manufacturing cost at client factory since with this modifier it is not necessary to sheet the de-vulcanized rubber on a rubber mill. De-vulcanized rubber powder can be easily packed in melt bags and directly used in master batch compounding. The benefit for our customers are lower energy costs and lower compounding costs.

Rubber Reclaiming Agent


DTDS : Devulcanizing Agent

DTDS is used in low pressure methods like Devulcanizer methods & Rotary Autoclave method and getting pressure only up to 200PSI to 300PSI and temperature up to 180 Degree Celsius to 210 Degree Celsius. The Results with this chemical is very good.

DXDS – Di Xylene Di Sulphide:

Di Xylene Di Sulphide or DXDS also know as Rubber Reclaiming Agent is used in high pressure method where the steam pressure goes up to 600PSI and temperature up to 250 Degree Celsius to 280 Degree Celsius and in this process underground Autoclave(fixed) is used.

TMBDS – Try Methyl Benzene Di Sulphide:

Try Methyl Benzene Di Sulphide also called as Tri Methyl Benzene Di Sulphide(another type of Rubber Reclaiming Agent) is very good Devocalizing Agent for the medium and direct heating process like Thermo Pec System and Microwave Systems or Infra red Systems etc., where only the temperature play an important roles of cracking media and steam pressure creates a homogeneity inside the rotary autoclave with the rubber molecules, addition of water creates the steam pressure and then temperature inside the rotary autoclave system. So, TMBDS play an important role in minimizing the pollution in these types of processes.

DPTMS – D.P.T. Mono Sulphide (Odorless):

DPTMS or D.P.T. Mono Sulphide (Odorless) (also another type of Rubber Reclaiming Agent) is used in medium pressure, Rotary Autoclave systems, kneeder systems, benbury sustems and inter mixer systems. It gives very good results in all the processes and reduces the pollution problems also up to the lowest level, where the systems pressure stands up to 350 PSI and temperature from 210 Degree Celsius and 220 Degree Celsius, which is quite suitable for the Reclamation processes.
