Ethylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity […]
1.EVA can be added to the formulation excipients very complex. Talk about some of the major bar. A scrap. After the product is made of scrap some of the excess material tail, side bars or something. They are already foaming over the. Such things are cost killer, using it can greatly reduce the production cost, of
Soles rather complex structure, broad terms, which may include all material and other bottom outsole, midsole and heel. According to the narrow sense, it refers only to the outsole, the general characteristics of common sole material should have abrasion, water, oil, heat, pressure, impact resistance, flexibility, and easy to fit feet, after setting easy to
Ethylene-vinyl acetate (EVA), also known as poly(ethylene-vinyl acetate) (PEVA), is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. Broadly speaking, there are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used. The EVA copolymer which is
Good or bad quality identification method: 1. Take a PVC yoga mat and don’t open it. Use your nose to smell the top of the mat. If there is a pungent smell, it is likely that the quality is off. 2. Use your thumb and forefinger to pinch the yoga mat and try out the
What is EVA Foam Scrap? It should be unclear to many people, what is this material, perhaps knowing it is a material but not knowing what it is mainly doing, what its market is. Let us first analyze the market analysis, policy and analysis of this material. At present, there is no clear standard for
