EVA wax emulsion is a functional material widely used in coatings, inks, textiles and papermaking industries, with excellent lubricity, wear resistance and dispersibility. When choosing EVA wax emulsion, how to evaluate its quality is an important step to ensure product performance. This article will analyze how to evaluate the quality of EVA wax emulsion from multiple perspectives to help you find suitable suppliers and products.
The stability of EVA wax emulsion is one of the important indicators to measure its quality. High-quality EVA wax emulsion should have good storage stability and avoid phenomena such as stratification, flocculation or precipitation. The evaluation methods include:
Observe the state changes of the emulsion during storage;
Check whether its performance is stable under different temperature conditions.
The particle size distribution directly affects the effect of EVA wax emulsion in the final application. High-quality EVA wax emulsion should have a small and uniform particle size distribution, which can ensure the smoothness and dispersion effect of the coating. It can be tested in the following ways:
Use a particle size analyzer to detect the particle size distribution;
Observe the smoothness after film formation.
The solid content and viscosity of EVA wax emulsion have a direct impact on its performance. Emulsions with high solid content and moderate viscosity usually have higher performance stability and use efficiency. When evaluating, the following points should be noted:
Check whether the solid content of the emulsion meets the technical parameter requirements;
Whether the viscosity is suitable for your specific application area.
During the application process, the abrasion resistance and gloss of EVA wax emulsion are important manifestations of its performance. For example, in coatings or inks, the emulsion needs to provide excellent wear protection while improving the gloss effect of the surface. Test methods include:
Testing through wear test equipment;
Comparing gloss test data.
The current market demand for environmentally friendly products is increasing, and it is particularly important to choose EVA wax emulsions with good environmental performance. High-quality EVA wax emulsions should comply with relevant environmental regulations, such as low VOC content and non-toxicity. When evaluating, you can refer to the environmental certification report and safety data sheet (SDS) provided by the supplier.
The supplier's qualifications and service quality are directly related to the reliability of the products you purchase. When choosing an EVA wax emulsion supplier, you can pay attention to the following points:
Whether the supplier has rich industry experience;
Whether it can provide complete technical support and after-sales service;
Whether the product has passed ISO quality management system certification.
