Ethylene Vinyl Acetate (EVA)
Ethylene vinyl acetate (EVA) is a copolymer of ethylene and vinyl acetate that is chemically similar to PE, with the difference that EVA has some vinyl acetate (VA) in the form of branching or branches that can be produced in different grades. Ethylene vinyl acetate (EVA) is one of the most widely used polymers in the group of acetates, which is used in various fields of manufacturing industries due to its absorption and compatibility with the environment.
EVA Granule Grades
EVA granules, or EVA compounds, are produced based on two weights of 18% and 28%. The uses of each are different depending on the type of consumption. The difference between 18% and 28% EVA granules is only in their appearance, degree of hardness, and softness. Copolymers produced from this combination are widely used in the packaging industry and the production of plastic goods.
VS430 is one of the famous grades of EVA granules, or EVA compound 18%, which is used in the production of foam, greenhouse films, shoe soles, and some other products. About 10 to 40% of the weight of EVA sheets is made up of vinyl acetate. The main uses of EVA granules or EVA compound include the production of EVA adhesive, slippers and sandals, sports equipment (boots, skis, and sports tatami), craft foam sheets, children's foam stickers, and artificial flower production. It is also used in the plastics, textiles, packaging, etc. industries.

EVA Granule Formulation
Ethylene vinyl acetate (EVA) is a copolymer of ethylene and vinyl acetate, where the weight percentage of vinyl acetate is usually from 10 to 50%. There are two methods of producing EVA:
- In this EVA production method, the most important part for the production of EVA Pellets is the reaction between ethylene and acetic acid with a palladium catalyst, which has the following molecular formula:
C2H4+CH3CO2H+1/2 O2-----CH3CO2CHCH2+H2O
- This EVA production method is more difficult than the other method. In this method, vinyl acetate is produced from the thermal decomposition of diacetate, during which vinyl acetate must be polymerized, which causes the production of unstable radicals. The molecular formula of this method is as follows:
(CH3CO2)2CHCH3-----CH3CO2CHCH2+CH3CO2H
The EVA production involves a process called copolymerization. This process uses heat and pressure to combine ethylene and vinyl acetate monomers to produce a copolymer chain with different levels of vinyl acetate, depending on the intended use of the material.
The formulation of EVA compounding can include various additives, polyolefin elastomers (POEs), foaming and cross-linking agents, and other components based on the desired properties of the final product.
Preparation of EVA compounding involves processes such as kneading and mixing to ensure good dispersion of the components in the compound. After mixing, the material is processed through extrusion to form sheets or rolls.
Extrusion involves pressing mixed materials through a mold to form the desired shape and thickness. Then it can be further processed to use the extruded material in different applications.
Formulation specifications for the production of EVA compounding are different depending on the type of application. For example, for the production of EVA copolymer foams, methods such as cross-linking through high-energy electron beam irradiation are used to achieve the desired properties.
The specifications of the formulation for preparing EVA foams may be different depending on the desired characteristics of the foams, and the effect of parameters such as radiation dose is considered in the formulation.
