First look at the EVA formula and final foam material requirements
Shoe materials, cushion materials and other EVA foam products have different density, colour and rebound requirements. When selecting, clearly identify the existing mixing, foaming and subsequent processes, record the main materials, fillers, and colorants, and then use actual foam materials to compare the impact of antibacterial additions on the original quality.
Select additives and masterbatch separately
| Add route | Specific products available for viewing | Main inspection items |
|---|---|---|
| Add liquid additives to the mix | AEM5700-BF, AEM5700-A06 | Dispersion, material mixing and foaming state |
| EVA carrier masterbatch mix | AEM5700-E10 | Carrier compatibility, particle dispersion and moulding performance |
| EVA application direction of PE carrier masterbatch | PE101, PE103 | EVA recipe matches masterbatch vector |
Create dosing records during the batching and mixing stages
Liquid additives and granular masterbatch are measured according to the model respectively, and then foaming occurs after thorough mixing. We record the ingredients and moulding conditions of the original formula and the added sample, and compare the cells and product functions.
Compare cells, colour and performance together
We incorporate cells, surface, colour, odour, density and rebound into foam development, and optimize the addition process by combining dispersion and moulding conditions.
Antifungal culture and antibacterial evaluation
Anti-mould and antibacterial use corresponding evaluation items respectively, using foam materials that have been formed in the same batch. The laminating, coating or cleaning scenarios are equipped with corresponding post-processing samples to analyze the performance of the two functions in actual use.

Frequently asked questions
How do BF and E10 access EVA ingredients?
BF liquid and E10 particle masterbatch adopt corresponding metering and mixing methods respectively. Engineers compare cells, density, appearance and functionality within the same EVA formula to provide product route recommendations.
How do you match EVA and PE carrier masterbatch?
We compare the mixing and dispersion of PE carriers in EVA, connect foaming and cells, density, and rebound evaluation, and provide corresponding addition and moulding suggestions.
If the anti-mould evaluation is passed, does it mean that the antibacterial requirements are also met?
Material culture and observation are used for mould prevention, and antibacterial evaluation is based on corresponding items. Both moulded foam materials are used, and the two functional performances are analyzed respectively.
How do you provide technical support when colour difference or uneven cells occur?
We compare the measurement, mixing, fillers and colorants of the original formula, analyze the dispersion and foaming conditions, and adjust the ingredients and small batch moulding process.
