Epoxy Resins Continue to Advance – even into Liquid Crystalline Form…
One of the things about science, technology and chemistry that you can count on is their ongoing progress. Innovative advancements are the hallmarks of these areas of study and their business applications as well. And epoxy resin improvements are certainly an integral part of this scientific evolution, as well as beneficial recipient, of this ongoing process.
Epoxy resin is used in a wide variety of applications but was hindered in the past due in some sectors due to issues with brittleness, impact resistance and internal stress. However, great strides have been made in the performance of this polymer in recent years. Improvements in the “toughness” of epoxy resin in the recent past have broadened its applications even further…
A number of studies have shown that the addition of a toughening agent such as liquid rubber has made great strides in the longevity and structural integrity of the solutions for which epoxy resin may be applied. Increased tensile and flexural properties are realized - enabling polymers that withstand much higher critical stress levels - making this already versatile solution viable for an even broader range of commercial and industrial applications. *
Epoxy Resin Developments
Recent developments in multifunctional epoxy resins have been brought about by advancements in manufacturing processes as well - through improvements in both digital and automation integration. The result is enhanced reinforced polymers that feature improvements in toughness and other mechanical properties that provide a decrease in shrinkage, excellent thermal and structural stability and inflammability. **
Already an excellent solution for myriad applications for decades; epoxy resins have nonetheless made significant advancements over the past twenty years. Scientists continue to advance these polymers by creating hybrids of epoxy resin combined with liquid crystalline materials – further improving such performance aspects including enhanced barrier properties, excellent resistance to brittle cracking and chemical resistance. ***
“Additionally, if the resins are modified or combined with the filler to form composites, the produced materials, due to their properties, significantly exceed the previous achievements,” writes Maciej Kisiel and Beata Mossety-Leszczak in Development in Liquid Crystalline Epoxy Resins and Composites - A Review. The authors explain, “This direction is so promising that it has been successfully studied for many years until today and is used in such different, yet sophisticated, fields.” Sectors referenced include aerospace, the pharmaceutical industry, dentistry and robotics.
