Center of Rubex Group

RubEx Group Testing Center

Central Laboratory of  OJSC Kurskrezinotekhnika has been functioning since the very foundation of the plant. And now it is a multifunctional, technically equipped unit of RubEx Group holding. The laboratory includes testing center, which is certified by the Federal Service for accreditation (accreditation certificate №RA.RU.21AB16, issued on the 7th of April, 2015.), in compliance with GOST ISO/IEC 17025-2009 according approved trial area for a wide range of non-tire rubber products.

The experience of this unit’s activities is 29 years. During this time it was held more than 7 million different tests, tested more than 1000 kinds of ingredients, worked out manufacturing parameters for more than 22 000 products, and created more than 1500 types of rubber compounds. The testing center has at its disposal highly qualified specialists and more than 150 different types of the most modern testing and measuring equipment.

We carry out a wide range of non-tire rubber goods for compliance with the physical and mechanical, chemical, anti-static performance, thermal aging, fire safety and other types of tests related to the relevant groups of products.
