Amorphous thermoplastic polymer with high transparency, relative
density (30 ℃/4℃) 1.188-1.22. High transparency, light
transmittance 90%-92%, higher than inorganic glass, and can pass
through ultraviolet light up to 73.5%. Refractive index 1.49. High
mechanical strength, good toughness, tensile strength 60-75mpa,
impact strength 12-13kj /m, higher than inorganic glass 8-10 times.
It is stretchable and directional, and the impact strength is
increased by 1.5 times. It has excellent resistance to ultraviolet
and atmospheric aging. The vitrification temperature is 80-100 ℃,
and the decomposition temperature is >200 ℃. The service
temperature is -40 ~ 80℃. Resistance to alkali, dilute acid, water
soluble inorganic salts, alkanes and fats. Soluble in
dichloroethane, chloroform, acetone, glacial acetic acid, dioxane,
tetrahydrofuran, ethyl acetate, insoluble ethanol, ether, petroleum
ether, etc. Good electrical insulation. PMMA has the advantages of
light weight, low price and easy to shape.
Product use
Its molding methods include casting, injection molding, mechanical
processing, thermal molding and so on. In particular, injection
molding, can be mass production, simple process, low cost.
Therefore, its application is becoming more and more extensive. At
present, it is widely used in instrument parts, automobile lamps,
optical lenses, transparent pipes and so on
Acrylic, also known as the plexiglass of special treatment, is a
replacement product of plexiglass. The light box made of acrylic
has the characteristics of good light transmittance, pure color,
rich color, beautiful and smooth, giving consideration to both
effects of day and night, long service life, and does not affect
the use. In addition, acrylic sheet and aluminum plastic board
profiles, advanced screen printing can be perfectly combined to
meet the needs of businesses, acrylic plastic is to improve the
level of stores, unified corporate image of the best outdoor
advertising form. "Yakeli" is a transliterated word, which is
ACRYLIC. It's a chemical material. Chemical name "PMMA" is a kind
of polyacrylate, commonly known as "after special treatment of
plexiglass", in the application industry, the raw materials of
acrylic generally in the form of particles, plates, pipes. Acrylic
acid is a generic name for both Acrylic acid and methacrylic acid
chemicals. Including monomers, plates, grains, resins and
composites, acrylic plates are made of methyl methacrylate (MMA)
polymerized plexiglass, which is derived from the commercial name
"Oroglas" (a PMMA plate) and comes from "Organic Glass" (also known
as plexiglass).
