Contec achieves major milestone: GumLab revolutionizes rubber industry research

“From the very beginning, quality was our top priority. Setting up the laboratory and installing the equipment for regular quality control was one thing, but these novel products do not always behave like regular, well-known virgin carbon blacks in every application. Over time, we realized that future investment in more advanced rubber testing will be crucial. Therefore, from the product development perspective, expanding our laboratory capabilities through rubber testing equipment was clearly a natural step forward to help our clients use our products with even better success. Achieving this goal demanded perfect synchronization of tasks between several departments, dedication, and specific knowledge at every stage” – Klaudia Końska, R&D Manager.

GumLab is equipped with cutting-edge test machines, enabling the development and testing of high-quality rubber compounds. The facility is equipped with advanced mixing and processing systems, as well as curing, rheological, physical, chemical, and mechanical testing capabilities. These capabilities allow Contec to evaluate critical properties affected by the fillers, such as recovered carbon blacks. The laboratory conducts comprehensive testing across multiple areas to gather complete knowledge about each application, compound or filler type. This includes:

  • Rubber Mixing & Processing – Experimental batch production using a Banbury mixer and a two-roll mill.
  • Cure and Rheology Analysis – Assessing the properties of rubber during processing and vulcanization to optimize performance and production procedures (ASTM D1646, ASTM D2084, D8059).
  • Physical Property Evaluation – Measuring filler dispersion and compound uniformity, essential for maximizing the benefits of recovered carbon black (ASTM D7723).
  • Mechanical Performance Testing – Examining tensile strength, tear strength, abrasion resistance, compression set, and hardness to predict real-world performance and durability (ASTM D412, D5963, D395, D2240).
  • Composition Analysis – Utilizing thermogravimetric analysis (TGA) and heating loss measurements to determine material composition and stability (ASTM D6370, ASTM D1278).
  • Aging Studies – Investigating the long-term resistance of cured rubber to environmental factors such as temperature fluctuations over time (ASTM D573).

“The launch of GumLab reinforces our commitment to innovation and sustainability,” said Przemysław Rakoczy, Business Development Director.” By investing in in-house research and development, we’re able to enhance our processes, elevate product quality, and provide even greater value to our partners in the rubber industry.”

Rubber testing opens for external partners

Beyond its internal research, Contec plans to make GumLab available for commercial use, offering external partners access to its advanced testing and development capabilities. This initiative will enable companies to leverage Contec’s expertise and infrastructure for their own rubber-related innovations and quality assessments.
