Since 2004, PTG/e has supported many companies with its knowledge and expertise in the field of polymers. Some of our projects have resulted in patents and scientific publications. Information on these can be found on the Patents and Scientific Publications sections of this website. PTG/e news and other relevant news can be found in the News section.
Examples of projects we have performed in the past are highlighted in the Cases section.
NEW UV-vis Spectroscopy
We are excited to announce a new addition to our infrastructure, UV-vis spectroscopy. UV-vis spectroscopy is a powerful tool for determining how molecules and materials interact with light. For a range of wavelengths, a beam of monochrome light is passed through the sample.
Suitable samples absorb part of the light within a specific wavelength range, which provides information on the concentration of certain molecules in a sample when compared to a reference of known concentration. Additionally, UV-vis spectroscopy can be used to follow the kinetics of (chemical) reactions occurring in a sample over time.
Curious about what UV-vis can do for you? Feel free to reach out and discover the possibilities
Small-Scale Polyolefin Reactors
Polyolefins are among the most widely used plastics in the world. With roughly 80 million tons being produced every year, polyethylene is the most well-known and most important polyolefin in the world. Other well-known polyolefins are polypropylene (PP), polybutylene (PB) and polyisobutylene (PIB). The properties of these polyolefins are crucial for the role they need to fulfill in all sorts of products such as packaging materials, furniture and electronics.
To be able to reach certain properties, the synthesis parameters must be controlled precisely during polymerization. In order to achieve the best settings, a lot of research is still being done. Because every system is different and requires its own set of parameters, optimization on small scale synthesis is a mandatory step before getting a pilot plant followed by industrial scale up.
PTG/e owns a unique platform of not one but five small scale polyolefin reactors. The reactors are designed for testing homogeneous as well as heterogeneous catalysts in slurry or solution. The four 125 mL and one 1 L autoclaves can be used to optimize the olefin polymerization process for different monomers, catalysts as well as synthesis conditions as they are equipped with extensive parameter monitoring. With such a setup, we can perform different experiments simultaneously, making it a highly efficient and quick way to test various parameters, such as temperature, pressure and ethylene/propylene uptake. In addition, olefin polymerization reactions can be quenched with carbon dioxide and the catalysts can be rejuvenated or can undergo chain transfer via the introduction of controlled small amounts of hydrogen.
If you are interested, please feel free to reach out, to discuss how our small scale olefin polymerization platform can benefit your projects.

NEW THF Size Exclusion Chromatography (SEC) system!
We are excited to announce a new addition to our infrastructure with the integration of our new Size Exclusion Chromatography (SEC) system of Agilent. This new SEC system utilizes tetrahydrofuran (THF) as the mobile phase, combined with a highly sensitive Refractive Index (RI) detector.
This THF-SEC is meticulously calibrated using Polystyrene (PS) standards, empowering us to determine the molecular weight of polymers within a wide range, from 200 up to 400,000 Da.
Our team at PTG/e is highly experienced with polymers of all kinds. By expanding our existing SEC systems line-up with this THF-SEC, we can now tackle molecular weight determinations of almost any polymeric material with utmost efficiency and reliability.
