Acrylonitrile - butadiene - styrene copolymer English name:
Acrylonitrile butadiene Styrene copolymers, hereinafter referred to
as ABS.ABS is a kind of high strength, good toughness, easy
processing and molding of thermoplastic polymer material
structure.ABS resin is, 1, 3 - butadiene acrylonitrile, styrene
terpolymer.Can be in 25 ℃ ~ 60 ℃ under the environment of
performance is normal, and has good formability, processing the
product surface is bright and clean, easy to dyeing and
electroplating.But also with a variety of resin with composite
blend.Now mainly used for metal, plastic and ABS.
ABS resin is (Acrylonitrile), 1, 3 - Butadiene Acrylonitrile
(Butadiene), Styrene (Styrene) of three kinds of monomer graft
copolymer.Its molecular formula can be written as (C8H8 C4H6 C3H3N)
x, but in fact is often contain the graft copolymerization of
With A mixture of acrylonitrile/styrene copolymer, among them, the
acrylonitrile accounted for 15% ~ 35%, butadiene accounted for 5% ~
5%, 40% ~ 60% styrene, emulsion method of ABS in proportion to the
most common is A: B: S = 22:17:6 1, and the method of ontology in
ABS B tend to be low, the proportion of about 13%.ABS plastic
molding temperature is 180-250 ℃, but had better not exceed 240 ℃,
the resin will be decomposed.
The material properties
The ternary copolymer of acrylonitrile, butadiene and styrene,
acrylonitrile A representative, B on behalf of butadiene, styrene S
The product has the characteristics of high strength, low
weight.Opaque, the pale ivory color appearance, non-toxic,
tasteless, the characteristics of both tough, hard, just slow
combustion, flame yellow, have black smoke, plastic softening after
burning, burning, issued a special cinnamon smell, but no molten
dripping phenomenon.Is a common engineering plastics.Weight: 1.05
g/cm3, molding shrinkage: 0.4 0.7%, molding temperature: 200-240 ℃,
dry conditions: 80-90 ℃ / 2 hours.
ABS resin is yellowish solid, has a certain toughness, density of
about 1.04 ~ 1.06 g/cm3.Its resistance to acid, alkali, salt
corrosion ability is strong, also can dissolve in organic solvents
to some extent tolerance.
ABS resin electroplating can be in 25 ℃ ~ 60 ℃ under the
environment of performance is normal, and has good formability,
processing the product surface is bright and clean, easy to dyeing
and electroplating.So it can be used in home appliances, toys and
other daily necessities.Common lego is ABS products.
With a variety of ABS resin with composite resin blend, such as
PC/ABS, PA, ABS/PVC/ABS, PBT/ABS, etc., to generate new properties
and new application areas, such as: combine the ABS resin and PMMA,
can produce the transparent ABS resin.
The chemical characteristics of
Comprehensive performance is good, high impact strength, chemical
stability, good performance.
Excellent welding pieces and 372 organic glass, make double color
plastic parts, and can be chrome plated surface, spray paint
Pieces have high impact, high heat resistance, flame retardant,
enhancement, transparency level, etc.
Liquidity than HIPS nearly, is better than PMMA, PC and so on, good
1, amorphous materials, liquid medium, moisture absorption, must be
fully dry, shiny plastic parts quality requirements must be long
preheating dry 80-80 degrees, 3 hours.
2, YiQu high temperature, anti-embrittlement temperature, but the
temperature is too high to decomposition temperature (> 270
degree).For high precision plastic parts, die temperature YiQu 50
to 60 degrees, the high gloss. Heat resistant plastic parts, die
temperature YiQu 60-80 degrees.
3, if you need to solve water lines, to improve the material
liquid, to adopt high temperature material temperature, the
anti-embrittlement, or change into the water.
Levels 4, such as forming heat or flame retardant material, the
production of 3 to 7 days after the mold surface residual plastic
decomposition, cause mould surface bright, clear in a timely manner
to die, and die surface to increase exhaust location.
5, high strength, impact resistance ability.
ABS is developed in the 1940 s general thermoplastic engineering
plastic, generally cars, appliances and electronic appliances is
ABS resin three applications, however, different regions and
countries there are considerable differences in their consumption
structure of ABS resin, the United States and Western Europe in the
field of car consumption is higher, accounting for about 22-24%,
Japan accounted for 15%, accounted for only 5% of the far east
region, Japan accounted for 27% in terms of equipment, 24% in
Western Europe, the United States accounted for 20%, in the far
east in the field of electrical and electronic proportion is as
high as 50%, Japan's Western Europe accounted for about 23-26%, the
United States accounts for only about 10%.Besides Japan in
groceries up to 28% of the United States in the aspect of building
materials application proportion accounted for 13-16%.Can ABS resin
injection molding, extrusion or hot forming.
