For manufacturers across various sectors, securing a consistent supply of high-quality raw materials is fundamental to operational success. Ethylene-Vinyl Acetate (EVA) copolymer, identified by CAS number 24937-78-8, is a highly sought-after polymer due to its versatile properties. As a leading manufacturer and supplier of fine chemicals in China, we aim to guide you through the process of sourcing this essential material.

EVA copolymer is a thermoplastic polymer formed by the copolymerization of ethylene and vinyl acetate. The specific grade of EVA is determined by the vinyl acetate (VA) content, which can range from a few percent up to 40% or more. This variation in VA content allows EVA to bridge the gap between traditional polyethylene and polyvinyl acetate, offering a unique balance of flexibility, toughness, clarity, and adhesion. Understanding these properties is key when you decide to buy Ethylene-Vinyl Acetate Copolymer.

Key Properties of EVA Copolymer:

  • Flexibility and Toughness: EVA exhibits excellent flexibility, even at low temperatures, making it suitable for applications subjected to stress and impact.
  • Adhesion: The polar nature imparted by the vinyl acetate groups enhances EVA's adhesive capabilities, allowing it to bond well with various substrates.
  • Softness and Tactile Properties: Compared to polyethylene, EVA is softer and has a more 'rubbery' feel, contributing to its use in products requiring comfort and grip.
  • Processability: EVA is readily processed using conventional thermoplastic methods such as extrusion, injection molding, and blow molding.

Major Industrial Applications of EVA:

When you plan to purchase EVA CAS 24937-78-8, consider its widespread use in:

  • Hot Melt Adhesives: EVA's tack and fast setting time make it a primary component in hot melt adhesives for packaging, bookbinding, and woodworking.
  • Films and Sheets: Used for flexible packaging, agricultural films, and protective sheeting due to its toughness and clarity.
  • Footwear: Widely incorporated into shoe midsoles and insoles for cushioning and shock absorption.
  • Wire and Cable Insulation: Its dielectric properties and flexibility are beneficial for jacketing and insulation.
  • Coatings and Sealants: Provides flexibility, adhesion, and weather resistance in various coating and sealant formulations.
