ABS Sheets and its various properties
ABS Sheets are the
common thermoplastic sheets, Its also known by Acrylonitrile Butadiene Styrene (ABS) Sheet. The glass transition temperature of
these sheets is 105 degrees Centigrade approximately. These ABS sheets do
not have any true melting point because these sheets are amorphous.
These sheets are terpolymer and are fabricated by polymerizing
acrylonitrite and styrene in the presence of polybutadiene. The
proportions produced can vary and acrylonitrite is produced about 15
to 35 %, styrene is 40 to 60 % and butadiene is 5 to 30 %. A
criss-crossed long chain of polybutadiene is the result along with
some poly styrene-co-acrylonitrite shorter chains.
The nitrile chains being polar attract
other neighbouring chains and together the chains are bound which
makes pure polystyrene and these sheets stronger. An impervious and
shiny surface is provided by the styrene. Resilience is provided by
the rubbery substance butadiene even at low temperatures. These
sheets for majority of applications can be utilized between -4
degrees and 176 degrees Fahrenheit or -20 degrees and 80 degrees
Centigrade and with temperature the mechanical properties of these
sheets vary. Rubber toughening creates the properties where
throughout the rigid matrix the distribution of fine particles of
elastomer takes place.
The most significant mechanical
properties of ABS Sheets are toughness and impact resistance. A
variety of modifications can be made to these sheets to increase the
impact resistance, heat resistance and toughness. The proportions of
polybutadiene relative to acrylonitrite and styrene can be increased
to amplify the impact resistance although other properties are also
reflected with these changes. At lower temperatures the impact
resistance does not get down quickly. With limited loads excellent
stability is there of these sheets under load.
The polymers of ABS Sheets are
resistant to alkalis, aqueous acids, phosphoric acids, concentrated
hydrochloric, alcohols and vegetable, animal and mineral oils but
these sheets can be swollen by carbon tetrachloride, glacial acetic
acid and aromatic hydrocarbons. The polymers of these sheets are
attacked by nitric acids and concentrated sulphuric acids. The
polymers of these sheets are soluble in ketones, esters, acetones and
ethylene dichloride. For mechanical purposes these sheets are largely
used and these also have extensive range of frequencies and fairly
constant over electrical properties. These properties of these sheets
are very less affected by atmospheric humidity and temperature in
temperatures’ acceptable operating range.
When exposed to high temperatures these
sheets are flammable like a wood fire. These sheets will first melt
and then these would boil and at this point of time the hot flames
are produced by bursting of the intense vapours. Any persistent
organic pollutants are not produced when combustion takes place
because these sheets do not contain halogens and the toxic products
as a result of combustion produced are hydrogen cyanide and carbon
monoxide. These sheets can be recycled and are also damaged by UV
rays.
These ABS Sheets are light weight and these
are used in the manufacturing products of musical instruments like
piano movements, plastic clarinets, recorders, in drain waste vent
pipe systems, automotive trim components, golf club heads, enclosures
for electronic and electrical assemblies, blood accessibility medical
devices, white water canoes, buffer edging for joinery panels and
furniture, protective carrying cases and luggage etc.
