Expeka for the Rubber Industry.

The Expeka Method offers a new approach to address the ever-increasing complexity of manufacturing in the Rubber Industry.

Case Studies

The Expeka method has been used for a wide range of applications in the Rubber Industry. Its Flexibility and Capabilities are well-suited for the demanding world of Rubber. From the laboratory to the shop floor, the Expeka Method is a unique approach to experimentation.

Variation Reduction in Rubber Mixing

Goal : Reduce Non-Quality Losses caused by high batch-to-batch variations.

Outline: 15 variables/15 responses/42 runs

Results: Non-Quality losses reduced by 50% and productivity increased by 25%

New Compound Formulation

Goal: Develop a new recipe based on a CR-SBR polymer blend.

Outline: 15 variables/15 responses/30 tests

Results: Reliable models of the physical properties of the cured compound and rheological properties of the uncured compound. Ability to optimize for minimum recipe cost.

Modification to an Existing Compound

Goal : Minimize Weight-Based Cost without compromising physical characteristics.

Outline: 3 variables/16 responses/17 runs

Results: 15% Weight-Based Cost Reduction.


Goal : Solve poor dimensional stability, rough surfaces and heat buildup of the extrudate by studying different types of carbon black.

Outline: 7 variables/18 responses/19 runs

Results: Achieved better Extrudate at a lower cost.

About the Expeka Method

The Expeka Method is a systematic approach to experimentation facilitating the investigation and understanding of complex processes like rubber Mixing and Compounding.


Its AI-supported algorithms are used to guide experiments by suggesting the best combinations of factors that maximize new information and help define the boundaries of the process. It can be useful in new compound development, modifications to existing compounds, scale-ups and solving mixing and processing problems.


Results from each new test are taken into account for the selection of the next test to be performed. This interactive approach helps reduce the number of tests required to achieve a sufficient understanding of the process factors and their interactions.


The resulting data set contains all the information required to create predictive models of the process and identify the relations between the variables and responses to address or eliminate problems. The Expeka Method is a powerful tool to study, control, and understand the complex processes of the Rubber Industry.
