The full name of EVA is Ethylene Vinyl Acetate. EVA in Chinese means "ethylene-vinyl acetate copolymer" or "ethylene-vinyl acetate". It is an elastic polymer made of ethylene and vinyl acetate. EVA is light and flexible, and has shock-resistant elasticity like rubber. It also has stable chemical properties, a low melting point, and is easy to process and shape. Therefore, EVA has a wide range of applications.
Features
Waterproof: High-density pore structure, not easy to absorb water, high waterproofness.
Sound insulation: High damping sound absorption, with good sound insulation effect.
Seismic resistance: High elasticity and seismic resistance, with good buffering capacity.
Thermal insulation: Heat-resistant and UV-resistant, heat-insulating and cold-proof.
Insulation: Excellent insulation performance, able to prevent the flow of current.
Corrosion resistance: Oil-resistant, alcohol-resistant, acid-resistant, and alkali-resistant, with good corrosion resistance.
Processability: EVA material is easy to dye, cut and cut, hot-pressed, and glued.
Environmental protection: EVA material is non-toxic and odorless, recyclable and reusable.
EVA material
The weight percentage of vinyl acetate is usually 10% to 50%, and the rest is ethylene. EVA is presented in three different materials: film, foam, and rubber, and the change in its texture depends on the content of vinyl acetate (VA).
Uses
EVA materials have a wide range of applications, among which EVA products are mostly foamed soles, and others include EVA glue,
EVA film, EVA foam, etc.
EVA glue
When EVA is heated to a certain degree, it becomes a liquid with a certain viscosity, which can be used to make adhesives and binding glue.
For example: hot melt glue, foam glue, back glue, binding packaging glue, plywood glue
EVA film
EVA film is flexible, durable and transparent, and can be used for functional greenhouse film and packaging film.
For example: greenhouse agricultural greenhouse film, solar EVA film, HDPE engineering waterproof film, packaging film
Insulating material
EVA material has good flame retardancy and good electrical insulation ability.
For example: wire and cable insulation, pipeline insulation coating
Foaming material
EVA foam has good elasticity and has functions such as shockproof, pressure-proof, heat insulation and heat preservation.
For example: protective pads, anti-collision foam, sound insulation, yoga mats, toys, helmets, fishing rods
EVA rubber
EVA rubber has good resilience, durability and is easy to shape, as a substitute for traditional rubber.
For example: EVA slippers, insoles, soles of sports shoes or casual shoes, rubber wheels
