Areas of research

#1 – Modifiers rubber compounds Members of the Department develope new high-performance rubber cord adhesion promoters on the basis of the molecular complexes of unsaturated dibasic organic acids (maleic and/or fumaric) with hexamethylenetetramine.

Preliminary tests show that the rubber containing this modifying complex exceed rubber, containing modifier RU.

#3 – Silicic acid fillers Members of the Department explore new additives to enhance performance rubbers containing colloidal silica and silanes.

The introduction of these additives will improve the technological properties of the rubber mixes (reduce viscosity, improve the dispersion of colloidal silicic acid) and vulcanizates characteristics (increase the strength and elongation, to reduce the hysteresis loss). Currently the content of additives and silane curing agent is optimizing.

Areas of research

#4 – Nano-sized technical black carbon Urgent track, including the tire industry is the ability to study the use of rubber in the carbon nanomaterials.

Currently the effect of doses of carbon nanotubes on the properties of the elastomer compositions is studying.

Areas of research

#5 – Diffusion of plasticizers Great importance for the prediction of the behavior and characteristics of polymeric materials has study of diffusion of ingredients. Obtained data will allow to create a mathematical model of the processes of diffusion of the plasticizer in the polymer, which will predict the properties of the finished product.

Areas of research

#6 – Biodegradable polymers Work on the creation of biodegradable polymer composites based on polyhydroxybutyrate is conducting at the Department.

We plan to create promising modern polymer materials to degrade in the soil and in the open air.
