「Co-polyacrylate Silver Salt」 - World Patent Development Technology
Silver-containing dressing formulation technology
Advantages of silver polymer in the application of silver-containing dressings
(1) An effective and safe supplier of silver ions Compared with the silver raw materials currently used in silver-containing dressings, silver polymer is a relatively effective and safe supplier of silver ions. Compared with small molecule materials, polymer materials are safer The above has surpassed a lot, and the silver ions bound to the polymer have been given relatively high safety. The test results of SGS show that the smaller molecular silver ions have a better antibacterial effect, which also gives the silver high Potential competitive advantage of molecules in silver-containing dressings
(2) Water Solubility
The water solubility of silver polymeric presents two competitive advantages. Firstly, it enables more effective delivery of silver ions to water-containing wound environments compared to most existing silver-containing dressings. Secondly, it facilitates easier processing and incorporation into dressings, particularly seamless integration with existing hydrogel materials, resulting in antimicrobial hydrogel dressings.
(3) Polymer Compatibility
In addition to its safety advantages, polymers exhibit excellent compatibility with certain polymer dressings. Especially with hydrogel materials like alginate, chitosan, and NaCMC, silver polymeric can be uniformly dispersed within these hydrogel materials, imparting exceptional antimicrobial properties.
(4) Adjustable Characteristics and Properties
Adjusting the silver content can modify the material properties of Copolyacrylate Silver Salt. By tailoring the silver content, we can meet the diverse requirements of various wounds and stages of wound healing, thereby altering the characteristics of Copolyacrylate Silver Salt to match the specific needs of different wound situations.
Silver polymer patented technology
Safety
Will not penetrate the skin and mucous membranes. Because the molecular weight of silver polymer is tens of thousands of times that of general small molecule antibacterial agents, silver polymer will not penetrate the skin and mucous membranes into the human body and affect human health. It is a very safe antibacterial agent. The pH is neutral and no irritation.

SilvRight silver-containing polymer dressing formulation technology
The adjustment of the silver content can change the physical properties of the silver polymer. The research and development technology of SilvRightd can adjust the silver content and change the characteristics of the silver polymer to meet the various needs of wounds.
Advantages of silver polymer in the application of silver-containing dressings
Effective and safe silver ion supplier
Compared with the silver raw materials currently used in silver-containing dressings, silver polymer is a relatively effective and safe provider of silver ions. Compared with small molecule materials, the safety of polymer materials is much higher than that of small molecule materials. It is combined with polymer materials. The silver ion is also given relatively high safety, and the test results of SGS show that the smaller molecule silver ion has a better antibacterial effect, which also gives the silver polymer a potential competitive advantage in silver-containing dressings.
Dissolved in water
The water solubility of silver polymer represents two competitive advantages. The first is that it can provide silver ions to the water-containing wound environment more effectively than most existing silver-containing dressings. The second is that it can be processed and added to the environment more easily. Among the dressings, especially, it can be perfectly combined with the existing hydrogel dressings to produce antibacterial hydrogel dressings.
Polymer
In addition to the safety advantages of polymers, they also have excellent compatibility with some polymer dressings, especially polymer hydrogel materials such as alginate, chitosan, NaCMC, and silver polymers can be evenly dispersed in these The water glue material gives them excellent antibacterial properties.
Adjustable characteristics and material properties
The adjustment of the silver content can change the physical properties of the silver polymer. We can adjust the silver content and change the characteristics of the silver polymer to meet the needs of various wounds and wounds in each stage.
