Ethylene Vinyl Acetate (EVA)
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
EVA is a copolymer of ethylene and vinyl acetate monomer(VA). Its elasticity, heat sealing temperature, durability and permeability vary depending on the content of vinyl acetate monomers. It is used in a variety of areas from value-added products such as photovoltaic sheets to shoe soles, life vests, and more.

Frequently Asked Questions
What are the applications of Ethylene Vinyl Acetate EVA?
EVA is a copolymer of
ethylene and
acetic acid. The Chinese
chemical
name: Ethylene
Vinyl Acetate
Copolymer,
and
the English chemical name:
Ethylene Vinyl Acetate
Copolymer.
EVA
has a wide range of
applications,
especially in the
shoe industry, where it is
used in
the
soles and interior
materials of
mid-to-high-end
tourist shoes, hiking
shoes,
slippers,
and sandals. It is also
widely
used in
the field of
new energy, such as
photovoltaic
materials and solar cell
adhesives.1.
The main products of
EVA with vinyl acetate
content
below
5% are films, wires and
cables,
LDPE
modifiers,
adhesives, etc.; 2.EVA
products
with
vinyl
acetate content
between 5% and 10% are
elastic
films,
etc.; 3. EVA with 20-28%
vinyl
acetate
is mainly used
for hot melt adhesives and
coating
products; EVA is made by
copolymerization of LLDPE
(linear low density
polyethylene)
and
acetic acid (VA).
Comment on the water repellency of Ethylene Vinyl Acetate
According to the water resistance of EVA emulsion polymer, it can be divided into two categories: general purpose and waterproof. EVA polymer of general product grade has good rigidity, high bonding strength, but poor water resistance; Waterproof product brand EVA polymer has good flexibility, good water resistance, but low bonding strength. According to the application performance of EVA, copolymer composition and the third monomer type of copolymerization, EVA emulsions can be divided into two categories: adhesive and spinning. Adhesive type EVA is mostly used as a general purpose adhesive, and textile type adhesive is mostly used as a textile fiber adhesive, but there is no absolute boundary between the two.
What are the precautions for operation ?
Pleasec provide closed operation and good natural ventilation conditions. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a self-priming filter dust mask, chemical safety glasses, protective work clothes, and rubber gloves. Keep away from fire and heat. No smoking in the workplace. Use explosion-proof ventilation systems and equipment. Avoid producing dust. Avoid contact with oxidants and alkalis. When handling, light loading and unloading should be done to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Empty containers may have harmful residues.
