What is the reason why EVA toughens PP?

Effectively improve the impact resistance, elongation at break and melt index of filled PP, and the surface gloss of the product.

According to the official website of Huanyu High-tech Materials Co., Ltd., the reason for EVA-toughened PP is that the mixture of EVA-modified filled PP can effectively improve the impact resistance and elongation at break of filled PP. The rate and melt index are also improved, and the surface gloss of the product is also improved. Due to the influence of molecular structure and aggregation state, PP has shortcomings such as high brittleness, high shrinkage rate, and prone to warping deformation of injection molded products, which limits its application in engineering.

EVA is a polymer of ethylene and vinyl acetate. The Chinese scientific name is: ethylene-vinyl acetate polymer (ethylene-vinyl acetate polymer). Applications of EVA The field is quite wide, and my country's market consumption is constantly increasing every year, especially in the shoemaking industry, where it is used in mid-to-high-end travel shoes, etc.
