Product Name:Ethylene-Vinyl Acetate Copolymer (EVA)
English Name:Ethylene-Vinyl Acetate Copolymer (EVA)
CAS No.:24937-78-8
Aliases:EVA, EVA resin, Ethylene vinyl acetate copolymer
Molecular Formula:(C₂H₄)ₓ(C₄H₆O₂)ᵧ
Physical Properties:White semi-transparent granular solid with a density of approximately 0.948 g/cm³ and a melt flow rate of 4 g/10min (190°C/2.16kg). It exhibits good flexibility, high elasticity, crosslinkability, and optical performance, along with low-temperature softness and resistance to stress cracking. The vinyl acetate content varies between 9% and 28% depending on the grade, with corresponding variations in density and flowability.
Uses:Primarily used in the production of crosslinked foamed materials such as foamed shoe soles and crosslinked foam boards. It is also applied in shock-absorbing cushioning materials, masterbatch carriers, extruded building materials (pipes, profiles), and hot-melt adhesives. Due to its high elasticity and flexibility, it is especially suitable for applications requiring cushioning and resilience.
Technical Specifications:
Density: 0.948 g/cm³
Melt flow rate: 4 g/10min (190°C, 2.16kg)
Tensile strength: 13.7 MPa
Elongation at break: 800%
Flexural modulus: 6.86 MPa
