Russian and Serbian scientists have developed a safe alternative to phthalates, components commonly used in medical devices. They replaced them with aliphatic acid esters. This significantly improved the safety of plastic products for human health, according to Irina Vikhareva, Senior Researcher at the Nanotechnology Research and Education Center of the South Ural State University (SUSU), Candidate of Chemical Sciences.
The scientific problem that we solved together with our Serbian colleague Dragan Manojlovic is that plastic products based on phthalates, which are widely used in medicine, are not safe for humans. They can lead to plastic migration and its entry into the body. We have created and obtained a new type of plastic, where aliphatic acid esters were used instead of phthalates.
She said that industrial samples of suspension polyvinyl chloride, supplied by a Russian company, were used as a basis for creating new types of plastics. Instead of phthalates, aliphatic esters of adipic, azelaic and sebacic acids were taken. A special chemical plant was used to synthesize these esters.
Plastics containing aliphatic acid esters are more resistant to high and low temperatures compared to traditional ones.
Earlier, Petrozavodsk State University created a program designed for computer analysis of welded joints used in industrial production. The model is based on neural networks and is part of a hardware and software complex. The complex includes a camera and a computing device that provide the transmission and processing of information in real time.
