Title: Jussi Laurell: Innovator in Polymer Technology
Introduction
Jussi Laurell, a distinguished inventor based in Borgå, Finland, has made significant contributions to the field of polymer technology. With a remarkable portfolio of three patents, Laurell has been at the forefront of innovations that enhance the performance and durability of polymer products, particularly in the pipe manufacturing industry.
Latest Patents
Among Jussi Laurell's latest patents is a groundbreaking polymer composition specifically designed for pipes. This multimodal polymer composition consists of a multimodal polyethylene with a density ranging from 0.930 to 0.965 g/cm³. Notably, it maintains a viscosity at a shear stress of 747 Pa of at least 650 Pa.s. This composition is characterized by both a low molecular weight ethylene homopolymer fraction and a high molecular weight ethylene copolymer fraction, where the weight ratio of the LMW to HMW fraction is strategically set between 35-55 to 65-45. The resulting pipe exhibits exceptional properties, capable of withstanding stress levels up to 8.0 MPa gauge for a duration of 50 years at a temperature of 20°C. In addition, this pipe is designed to resist rapid crack propagation under harsh conditions and boasts a slow crack propagation resistance of at least 500 hours at specified conditions.
Another important patent from Laurell is the process for the reduction of reactor fouling in radical-initiated high-pressure polymerization of ethylene (co)polymers. This innovative process involves the addition of an adhesion-reducing silicon-containing compound, such as hexadecyl trimethoxy silane, in amounts ranging from 0.001% to 3% by weight, relative to the polymer produced, significantly improving the efficiency of the polymerization process.
