ProductsFor material analyses and development works we have created (and recently published) a new principle for rheology polymer structure analyses based on control theory and polymer-chain dynamics. The associated computations are performed using self-coded RheoPower and DataPower software packages.
We have found a linear relation between structure and different viscoelastic properties, which potentially offers widespread applications.
The best proof of principle is the favourable computation results obtained from the new theory. RheoAnalyzer is used to model viscosity flow thousands of times more accurately than previous models.
CustomersConfidence is essential in our consultancy work and software sales. Polymerization plants, laboratories, universities and some of the world’s leading chemical companies are using our software and consultancy services, from China to the United States and Europe.
Our cooperation partners and customers also need tailored software and interfaces for use with their own software products.
MissionFor decades it was hoped that linear relations would be found between polymer structure and properties. We have combined strong practical extrusion experience, academic research and modern software application development tools to find solutions to well-known major problems in the field. Our interests can be summarized as follows:
Developing new polymer technologies for manufacturing industry based on the actual relations between structure and properties.
Finish line and goalOn these pages are proved that macromolecules do not behave exactly similar way as classical Maxwell models and continuum done “dogmatic” models copied from dielectric phenomena, which describes for viscoelastic materials originally only on stress relaxation states. - Our presented principle with tight scientific and well approved mathematical background is free of these limitations and useable for different type flows and states of heterogeneous things and materials.

InventorTommi Borg is a world expert on polymer rheology analyses and plastics manufacturing. Tommi started in 1968 as a young trainee operating extruder lines at factories and performing experiments at polymerization plants during school vacations, during which he made his first rheological calculations for engineers. These experiences were followed by formal studies during the 1970s in physics and computer science at the University of Oulu, which led to his first self-coded programs in 1975, a Finnish patent being granted in 1977 and an international patent being granted in 1989 for a heat-shrinkable sleeve. He has decades of experience in engineering, modernizing and inventing extrusion lines, die designs and extrusion processes. He worked at extrusion plants from 1979 until 1993, since when he has worked as an independent researcher and plastics and software consultant.
During the 1970s Tommi concentrated on developing models of viscoelasticity that were more accurate than the existing Maxwell and power-law models. This revealed a lack of accurate models for practical extrusion design and engineering, which further prompted his development of new models for different polymer melt flows, with solutions found using control theory. Tommi has given presentations on this topic at various international conferences since 1995, and the principles have recently been published in many papers in prestigious international journals. To capitalize on his fundamental studies with practical applications in the polymer industry, Tommi has written numerous RheoPower and DataPower software packages, dozens of copies of which have been sold to major polymerization plants and research laboratories.
