First identify the PU foam material to be protected
We design antibacterial samples according to the use of PU soft foam, hard foam and products, and establish a comparison between the original formula and the added sample based on quality requirements such as contact surface, colour, odour, density and rebound.
Antibacterial raw material adaptation in PU formula
AEM5700-Z has a foam sponge application direction and can be used for candidate raw material screening. We carry out dispersion and foaming adaptation in specific PU formulas, design the adding position and sample amount, and coordinate foam material quality and antibacterial development.
Connect the feeding record and foaming record
We maintain the original PU component ratio and the benchmark moulding process, design the adding position and dispersion method of candidate raw materials during the batching stage, record the dosage, sequence and moulding status, and optimize the process by combining cells and antibacterial performance.
Foam quality is an inspection item in parallel with antibacterial
- Compare the cells, surface and uniformity of the original and added samples.
- Compare density, hardness, rebound and properties required for product use.
- Check to see if colour, odour, and back-end lamination or wrapping are affected.
- Use foam materials that have been formed and post-processed to evaluate antibacterial performance, and keep formula and process records.
Formula development and small batch process coordination
Small batch production continues to check the consistency of foam materials at different locations. After adjustments to the original formula, fillers, colors, foaming conditions or subsequent processes, review the original quality and antibacterial performance; separate samples will be arranged based on actual applications for long-term use, cleaning or friction requirements.

Frequently asked questions
Can PU foam directly use the amount of EVA foam added?
PU is added according to its own components and foaming process design. Engineers provide process suggestions for the formula through a small amount of ingredients and moulded samples, as well as dispersion, foaming and antibacterial evaluation.
Z has a sponge application direction, does it mean it is suitable for all PU soft foam and hard foam?
Engineers carry out dispersion and foaming adaptation of candidate raw materials in specific PU formulas, and select routes based on the original performance and antibacterial performance of the foam material.
Which component of the PU formula should be added to the antibacterial raw material?
The adding position is designed according to the PU formula components and mixing methods. We provide measurement, dispersion and moulding suggestions, and keep component proportions, sequences and process records.
The antibacterial results are normal but the rebound or cells have changed. Can it be produced directly?
We simultaneously analyze antibacterial, cells, density, rebound, appearance and post-processing, adjust ingredients and moulding conditions, and cooperate with small batch trial production.
