Plastic antibacterial agent Plastic antifungal agent

Plastic antibacterial and mildewproofing agent
It is a broad-spectrum, highly efficient inorganic powdery antibacterial and mildewproofing agent produced by adding bactericidal metal ions into the inorganic carrier structure. It has antibacterial properties, durability, Compared with existing antibacterial agents, it has high advantages in terms of discoloration resistance, UV resistance and heat resistance. It has been widely used in rubber and plastic fields such as home appliances, synthetic fibers, packaging materials, household products, sanitary products, building materials products, and stationery products.

3. Application and performance description of (powder)
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,,M,,B,/B, unsaturated polyester and other resins.
The heat-resistant temperature is excellent (℃). 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 to make an injection compound containing a high concentration of sulfide (the concentration is usually %) and dilute it when using it. To the specified concentration, dispersion can be improved more effectively.
Recommended addition amount: ..%, the specific product addition ratio needs to be determined through testing.
The antibacterial performance in polypropylene has been evaluated: the antibacterial rate is .%%% when the added amount is .%%%.
4. Precautions when processing and storing (powder)
Because it is an ultrafine substance, it has a certain degree of hygroscopicity. Please be careful to avoid moisture absorption
