Nanotechnology Experts in Iran Make Antibacterial Polyethylene Masterbatch
‘Parsa Polymer Sharif’ and ‘Taban Andish Berjis’ companies have made the product which is a ceramic nanoparticles-modified polyethylene masterbatch, in which oxide nanoparticles are added to the polyethylene matrix.
The addition of ZnO nanoparticles to the polyethylene masterbatch has resulted in emergence of antibacterial activities.
The special masterbatch can be applied in manufacturing automotive parts and accessories, home appliances, containers, electrical/electronic devices, packaging, and other industries.
In a relevant development in April, an Iranian knowledge-based firm had introduced new packaging method for foodstuffs which is safe and environmentally friendly and keeps the food item fresh for longer time by using a special masterbatch.
The managing director of an Iranian knowledge-based company, Foad Mashayekhi, said that he and research teammates have designed and introduced oxygen-reducing masterbatches (OBMB) to achieve food packaging methods with safety features and longer storage time.
“This product is specially designed to reduce gas passage and absorb oxygen trapped in the package, which reduces the volume of oxygen passing through the packages. This masterbatch added to the main polymer during the production process, and it can be produced based on different polymers according to the customer's demand,” he said.
“Reducing gas infiltration, being anti-UV and antibacterial, increasing inhibitory properties, preventing color change in the product and oxidation, improving mechanical properties and resistance against heat, increasing the shelf life of the product, and maintaining the quality of food containing lipids are among the properties of these polymers,” according to the researcher.
Mashayekhi said that his company's product is plastic raw materials and his customers are a variety of industries such as household items, auto industries, water and gas transmission pipelines that require large steel pipes with plastic coating.
