How should ABS material choose antibacterial agent

Antibacterial plastic is a kind of plastic that inhibits or kills bacteria, molds, alcohol mother bacteria, algae and even viruses in the use environment, and keeps itself clean by inhibiting the reproduction of microorganisms. At present, antibacterial plastics are mainly obtained by adding a small amount of antimicrobial agents to common plastics.

In the use of antibacterial plastics, first of all, the necessary requirements for the physical, chemical, mechanical and other properties of the plastic as a basic material should be met, and at the same time, the requirements for the special function of antibacterial and the resulting additional factors should be considered. Therefore, antibacterial plastics should have good mechanical strength appearance, chemical stability, good machinability. In terms of antibacterial, antibacterial plastics should be able to adapt to the use environment, and should have high efficiency, broad spectrum, long-term antibacterial properties. Because the antibacterial plastic contains a small amount of antibacterial agent, so the requirements of the antibacterial agent used to achieve the specified health safety, and make the ultimate antibacterial plastic products to achieve non-toxic, no smell, harmless to the environment.

ABS plastic is acrylonitrile (A), butadiene (B), styrene (S) three monomers of the terpolymer, the relative content of the three monomers can be arbitrarily changed, made of various resins. ABS has the common performance of three kinds of components, A makes it resistant to chemical corrosion, heat resistance, and has A certain surface hardness, B makes it has high elasticity and toughness, S makes it has the processing and forming characteristics of thermoplastic plastic and improve electrical performance. Therefore, ABS plastic is a kind of raw material is easy to get, good comprehensive performance, cheap, widely used "tough, hard, rigid" material. ABS plastics have been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemical industry.

ABS products related to antibacterial industry: home appliances, bathroom, sports equipment, etc

This requirement has the following characteristics:

A: production performance: antibacterial agent as low as possible, can not affect the mechanical performance such as tensile, surface finish is high, can not affect the surface flatness.

Two: color requirements: color stability, to maintain a stable product appearance!

III. Safety: RoHS and REACH shall be met. In certain circumstances, must meet the GB9685 (through the GB4806 test), FDA precipitation test, can not bring secondary pollution!

So how should we choose antimicrobial agents? Evenclean recommends inorganic antibacterial agent, which can well meet the food contact level, low addition ratio (0.5%-0.6%), temperature resistance up to 400-500℃ or more, color stability, no precipitation, no odor. Such as our JP-940 (silver antibacterial agent) JP-928 (zinc antibacterial agent). Eliminate safety, odor, color, and precipitation problems associated with organic antimicrobials. Can be stable through GB/T 31402, GB/T 21551, ISO 22196, JIS Z 2801 GB/T 36391 and so on.
