Göran Spetz had, when he started Elastocon, a great deal of experience in rubber technology, first as lab manager at Firestone in Borås for 11 years and later  as manager for the rubber testing at the National Testing Institute for 12 years.

Göran Spetz has participated in the standardisation of rubber test methods in the Swedish standards and in ISO TC 45 since 1978. During the development of the ISO test method standard for testing of stress relaxation Göran developed an instrument for continuous testing of stress relaxation. Later on some companies showed interest in buying this instrument. However, as with many home built instruments, the equipment needed further development to be sold commercially. Göran obtained permission from the testing institute to start a company and further develop the stress relaxation tester in his free time and after two years of further development the relaxation testing system was ready.

To be able to do the relaxation tests at elevated temperatures, Göran needed a precise ageing oven and so the first cell ageing oven was developed. The first cell oven was sold to a company even before it was finally designed, it was only a sketch on paper.

The next instrument developed was the fogging tester. A customer needed a fogging tester and Elastocon built one.

The business grew and when Göran got the offer to represent a manufacturer of rheological testing instruments in Scandinavia, he decided to leave the testing institute and work with Elastocon full time in 1989. The company also moved from the Spetz family garage to new renovated premises at a former hospital in Borås.

Since then Elastocon has developed about 30 new instrument  systems, from compression test rigs to automatic testing instruments. The design, development and electrical assembly is done by Elastocon  and the mechanical manufacturing by several subcontractors.

Elastocon also started a calibration service 1993 and is now able to  calibrate most testing instruments with traceability to international references.
