PP plastic antibacterial agent plastic mildew agent

Plastic antibacterial and antifungal agents are a type of broad-spectrum and highly efficient inorganic powdery antibacterial and antifungal agents produced by adding bactericidal metal ions into the inorganic carrier structure. In terms of heat resistance and other aspects, it has high advantages compared with existing antibacterial agents. It has been widely used in rubber and plastic fields such as home appliances, synthetic fiber packaging materials, household products, sanitary products, building materials, stationery products, etc.

2. Product Features
It has significant inhibitory effect on Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhi, Salmonella aerogenes, Candida albicans, Aspergillus niger, Aspergillus mucosus, Penicillium funiculata, etc. It can inhibit the occurrence of odor in products under harsh conditions and prevent mildew of products.
Good process compatibility. Does not significantly affect flow performance, does not produce pores and stains.
Provides long-lasting anti-bacterial and anti-mildew effects.
Does not change the transparency, impact resistance and color of the product.
Resistant to UV light and has excellent discoloration resistance.
Application and performance description of the three powders
It can be applied to the matrix resin in the same way as adding inorganic pigments. So far, it has been processed into various resins such as /B unsaturated polyester and other applications.
The heat-resistant temperature is excellent at ℃, and within the range of the general molding temperature of about ℃, there will be no problems with physical properties and antibacterial properties, and the color of the product will be stable under ultraviolet light.
A special coupling dispersant is added to ensure that the inorganic antibacterial powder is evenly dispersed in the resin phase. However, it is recommended that the injection compound containing high concentration be diluted to the specified concentration during use. Can more effectively improve dispersion.
Recommended addition amount, specific product addition ratio needs to be determined through testing.
The antibacterial performance in polypropylene has been evaluated with an antibacterial rate of 0.01%.
Precautions when processing and storing the powder
Since it is an ultra-fine substance, it has a certain degree of hygroscopicity. Please be careful not to absorb moisture.
