🔬 At a molar fraction of 5% vinyl acetate, the mechanical properties of EVA (ethylene vinyl acetate copolymers) become very similar to those of soft PVC.EVA is flexible in its own right, which gives it a number of advantages, such as the disadvantage of avoiding the migration of plasticizers, which is the main reason for the gradual replacement of PVC.

💪 These copolymers have a higher modulus and better processing properties than typical elastomers and do not require vulcanization considerations. Polyvinyl alcohol can be obtained by hydrolysis of polyvinyl acetate. Poly(vinyl alcohol) is an atactic cubic polymer but does not disrupt the lattice structure due to the small hydroxyl groups. Therefore, ester bases that are not sufficiently hydrolyzed reduce crystallinity and the number of intermolecular hydrogen bonds.

💧 Highly hydrolyzed poly(vinyl acetate) (containing fewer unhydrolyzed ester groups) has a higher crystallinity. As the degree of hydrolysis increases, the molecules become easily crystallized. If these molecules are not sufficiently dispersed before dissolution, hydrogen bonding will cause them to associate with each other. In order to achieve hydrolysis levels above 98%, manufacturers need to operate at a low temperature of 96°C to ensure that the larger molecules have sufficient thermal energy to dissolve.

EVOH (ethylene vinyl acetate copolymer) is a polymer with excellent gas barrier properties and is commonly used in food packaging, medical products, and protective materials for automotive and electronic products. Due to the high molar fraction of vinyl acetate, EVOH exhibits excellent gas barrier properties, especially for oxygen and nitrogen, and is therefore often used in food packaging to extend the shelf life of products.

The gas barrier properties of EVOH stem from its highly crystalline structure, which allows the molecular chains to be arranged more tightly, reducing the path of gas molecules through the material. In order to improve the properties of EVOH, different degrees of hydrolysis are often used to adjust the degree of crystallinity. The higher the degree of hydrolysis, the higher the crystallinity of EVOH and the consequent increase in barrier properties. Therefore, the degree of hydrolysis of EVOH must be strictly controlled during the production process to ensure that the material has ideal gas barrier properties. In China, EVOH products (EW-3201 and EW-3801) produced by Sinopec are highly recognized.

EVOH also offers significant advantages over other plastics in terms of chemical resistance, high temperature resistance and transparency. Its excellent processability allows it to be used directly in multilayer composites without the need for complex post-treatment operations during production, thus enhancing the functionality and economy of the final product.
