How to choose the appropriate EVA additive

Choosing the appropriate EVA additive requires comprehensive consideration of material properties, application scenarios, and performance requirements.

1. Clarify the application scenarios

Photovoltaic modules: Choose modified styrene elastomers or light stabilizers to enhance weather resistance and power stability.

Shoe materials and foam products: Priority should be given to wear-resistant and demolding agents to improve wear resistance and production efficiency.

Plastic products: use deodorizers and processing aids to optimize environmental and processing performance.

2. Pay attention to material characteristics

Hardness and Elasticity: Choose EVA additives with different hardness levels according to your needs, such as 20-25 degrees suitable for high protection scenarios, and 38 degrees suitable for general packaging materials.

Density and thickness: High density EVA additives are more durable and suitable for long-term use; Low density is suitable for scenes that require portability.

3. Performance requirements

Chemical resistance: Choose chemical resistant additives to ensure compatibility with drugs or chemicals, suitable for scenarios such as first aid kits.

Processing performance: Choose additives that are easy to cut, polish, and paste to reduce production difficulty and time costs.

4. Brands and suppliers

Reliability: Choose a brand with good reputation and word-of-mouth to ensure product quality and after-sales service.

5. Cost and Budget

Cost effectiveness: Choose EVA additives with reasonable prices based on the budget to avoid high or low costs.
