Narrow the selection range according to resin and appearance requirements
PP, PE, ABS, PC and other materials have different carriers, processing conditions and appearance requirements. We first distinguish between transparent parts, opaque parts, film and thick-walled parts, and then choose the directly added antibacterial powder or corresponding resin masterbatch. For parts with high transparency requirements, prototypes must be made with actual thickness to check light transmission, haze and colour changes.
Powder and masterbatch, two processing routes
| Processing requirements | Viewable Products | Supporting process services |
|---|---|---|
| Directly add plastic raw materials | AEM5700-A, AEM5700-A2 | Powder dispersion, colour and actual moulding conditions |
| PE, PP, PS, TPU, TPR and other organic antibacterial directions | AEM5700-MB | Specific resin formula, processing temperature and residence time |
| Follow the particle batching process | PP20, PE101 / PE103, ABS103 / ABS106, PC10, etc. masterbatch | The carrier resin matches the substrate, colour and moulding method respectively. |
is metered in during the raw material mixing stage
The powder and masterbatch are measured separately according to the model, and then mixed evenly before entering the injection moulding, extrusion and other processes. We record the resin, masterbatch, dosage and processing temperature, and provide ingredients and process suggestions for subsequent trial production.
Simultaneous inspection of antibacterial and product quality
We use the same batch of added samples and control samples to compare dispersion, colour difference, surface, size and material properties, and support the antibacterial evaluation of moulded parts and samples after cleaning, friction or aging.
Implement qualified samples into small batch production
After selecting the formula, engineers will connect raw materials, feeding and moulding records to small batch trial production, follow up on changes in resin, recycled materials, masterbatch and processing conditions, and provide dispersion and appearance adjustment services.

Frequently asked questions
How to measure antibacterial powder and masterbatch?
Powder and masterbatch use corresponding addition amounts according to their respective active compositions and carriers. Engineers recommend products based on the same base material and moulding route, and provide metering and mixing suggestions.
Which type of products should I look at first for transparent parts?
You can first check the high transmittance silver ion AEM5700-A and the transparent direction masterbatch matching the substrate, then make a sample with the actual wall thickness and colour materials to check the light transmission, haze and colour.
Why does the lab trial run normally, but colour spots or surface changes appear after mass production?
We analyze the changes, measurement, mixing, actual temperature and residence time of raw materials and colour masterbatch, and compare the same batch of raw materials with abnormal parts to locate the adjustment positions of the dispersion and moulding processes.
How do you conduct testing of plastic antimicrobial products?
We use moulded parts to carry out antibacterial evaluation, and simultaneously analyze the formula, thickness, dispersion and surface state; when there are cleaning, friction and aging scenarios, corresponding sample parts are used for evaluation.
