The Application of Antibacterial Masterbatch in TPU Cast Film
The application of antibacterial masterbatches in TPU cast films mainly lies in endowing TPU cast films with antibacterial properties, expanding their application fields, and enhancing the added value and market competitiveness of the products. The following is a detailed introduction from four aspects: the characteristics of antibacterial masterbatches, their application methods in TPU cast films, application effects, and application fields
The characteristics of antibacterial masterbatches
High-efficiency sterilization: Nano-antibacterial masterbatch refines antibacterial agents to the nanometer level through nanotechnology, featuring a larger specific surface area and higher activity, capable of rapidly killing bacteria, viruses and other microorganisms.
Long-lasting antibacterial: The antibacterial effect of nano antibacterial masterbatch is long-lasting. Even after multiple washes or long-term use, it can still maintain good antibacterial performance.
High safety: It adopts natural or environmentally friendly antibacterial agents, which are non-toxic and harmless to the human body, and are safe and reliable to use.
Broad-spectrum antibacterial: It has a good killing effect on various bacteria, viruses and other microorganisms, and has a broad antibacterial spectrum.
The application mode of antibacterial masterbatch in TPU cast film
Blending modification: By blending and modifying antibacterial masterbatches with TPU substrates and granulating them, TPU materials with antibacterial properties are produced. For instance, Dalian Tianwei uses inorganic materials such as nano-silver and nano-zinc oxide as the main antibacterial components, and thermoplastic polyurethane elastomer (TPU) as the base material, with the addition of some dispersants and antioxidants. Through co-rotating twin-screw extruders for blending and modification granulation, it produces antibacterial masterbatches with a milky white and opaque appearance.
Direct addition: During the production process of TPU cast film, antibacterial masterbatches are directly added to the raw materials, and TPU cast film with antibacterial properties is made through processes such as melt extrusion and cast film molding.
The application effect of antibacterial masterbatch in TPU cast film
Excellent antibacterial performance: The addition of antibacterial masterbatch can significantly enhance the antibacterial performance of TPU cast film, effectively inhibiting the growth and reproduction of bacteria, mold and other microorganisms. For instance, some antibacterial TPU films can achieve a sterilization rate of over 99% against common bacterial species such as Escherichia coli and Staphylococcus aureus.
Stable physical properties: The addition of antibacterial masterbatch has a relatively small impact on the physical properties of TPU cast film, and can maintain its original excellent characteristics such as strength, toughness and wear resistance.
Safety and environmental protection: The antibacterial masterbatch uses natural or environmentally friendly antibacterial agents, meeting environmental protection requirements, being non-toxic and harmless to the human body, and is safe and reliable to use.
The application fields of antibacterial masterbatch in TPU cast film
In the medical field, antibacterial TPU cast film can be used to prepare antibacterial products such as medical devices, medical gloves, and medical shoe covers, effectively inhibiting the growth of bacteria and reducing the risk of cross-infection.
In the field of food packaging: Antibacterial TPU cast film can be applied to food packaging films, preservation bags and other products, effectively inhibiting the reproduction of bacteria and mold in food and extending the preservation period of food.
In the field of household goods: Antibacterial TPU cast film can be used to prepare antibacterial flooring, antibacterial mattresses, antibacterial curtains and other products, maintaining the cleanliness and hygiene of the home environment.
Other fields: Antibacterial TPU cast film can also be used in automotive interior parts, electronic device shells, sports equipment and other fields, enhancing the added value and market competitiveness of products.
