Synthetic Fill Material
Gordon Brush's selection of
synthetic fill brushes includes abrasive brushes and buffs, flow thru brushes,
forensic brushes, cleaning brushes, ESD and clean room brushes, and much more.
Some of the synthetic fill materials we use are: carbon steel, fiberglass,
nylon (abrasive; type 6; type 6.6; type 6.12, conductive; static dissipative),
polyester, PEEK, polyethylene, polypropylene, polystyrene, PTFE, Taklon, and
Thunderon®.
Carbon Steel
Carbon fiber is a very fine [0.00030] fiber of 94%
pure carbon. The fiber has a tensile strength of 525 Ksi, a tensile modulus of
33 Msi, and an electrical resistivity of 0.00055 Ohms-in.
Fiberglass
Fiberglass brushes are manufactured from spun glass
in two grades of material: course and fine. A gentle brushing action cleans and
polishes a variety of surfaces, metallic and non-metallic. Fiberglass brushes
will not contaminate or alter the electrical properties of the surfaces
cleaned. They are ideal for cleaning printed circuit boards, precious metal
surfaces, electrical contacts, solder joints, motor commumatators, or removing
epoxy, epoxy adhesives, rust, paint oxidation, corrosion, etc. They may also be
used for cleaning and polishing plastic molds.
Abrasive Nylon
Abrasive nylon is a long wearing filament
impregnated with silicon carbide particles. We stock several filament diameters
and silicon carbide particle sizes.
Nylon - Type 6
Nylon - Type 6
provides a good durable nylon with good recovery, temperature stability and
abrasion resistance at a low cost.
Nylon - Type 6.6
Nylon - Type 6.6 is a top quality, medium- priced
with higher stiffness, recovery, and abrasion resistance than type 6. It has
the highest heat distortion temperature of the three nylons at 300°F.
Nylon - Type 6.12
Nylon - Type 6.12 is a superior type nylon used in
applications calling for low water absorption. It has excellent bend recovery,
and abrasion resistance. This is the highest-grade nylon and they resist rot
and mildew and discourage bacterial growth. Type 6.12 Nylon bristles are FDA approved
and widely used in medical brushes, pharmaceutical brushes and food service
brushes.
Nylon – Conductive
Conductive nylon is a type of 6.6 nylon with an
electrically conductive coating suffused onto the surface for antistatic
bristle brush applications.
Static Dissipative Nylon
Static Dissipative Nylon is a type 6.12 Nylon with
a surface resistivity of 109 that does not shed or slough and is clean room
compatible. This also includes Statigo 9, a static dissipative nylon that is
thick enough to do mechanical work, and does not shed or slough and is clean
room compatible.
Polyester
Polyester bristle is a polymer that replaces horsehair. Its
features of toughness and high temperature resistance resemble those of Nylon,
but Polyester is noted for its ability to recover without whip or slapping
action – it will not mat. Polyester has excellent resistance to all acids,
alkalis, alcohols, gasoline, benzene and most cleaning solvents. It is a
medium- priced filament that resists mildew, bacteria and fungus growth.
PEEK
PEEK is a durable thermoplastic that offers good
chemical resistance and is ideal for high heat and corrosive environments. Peek
provides excellent flexural and tensile strength up to 480°F and
is a great alternative to polypropylene.
Polyethylene
Polyethylene is a soft durable material suitable
for applications where abrasion is to be avoided. These flexible bristles are
very efficient for thorough washing and polishing of delicate fruits and
vegetables. Polyethylene is ideal for soft wiping instead of a brushing action.
Polypropylene
Polypropylene is a versatile low cost filament used
for a wide variety of applications. Polypropylene will not absorb moisture or
odors and sheds dirt easily. It has excellent wet stiffness, abrasive tip cleaning
action, non- brittle, and is inert to most solvents, oil, acids, and chemicals.
It is, in fact, one of the most chemically resistant synthetic filament
materials.
Polystyrene is a material that has replaced natural
bristles for use where chemical resistance is needed. Its stiff aggressive
properties make it ideal for utility brushes, coffee urn brushes, deck scrub
brushes, and floor and garage brushes. Polystyrene bristles wear longer,
perform better, and yet carry a comparable price tag to natural bristles.
PTFE
A Polymer that is inert to most chemicals,
resistant to strong mineral and oxidizing acids, along with alcohols, ketones,
ethers, amines, esters, chlorinated compounds and common cleaning solvents.
PTFE has excellent property resilience up to 500°F.
Taklon
Taklon is made out of thermoplastic
polyester, sometimes referred to as PBT (Polybutylene Therephthalate). Taklon mimic
the characteristics of natural sable. It is a bit softer than the earliest
nylon brushes and a touch better at picking up powder than nylon, but not by
much. Talkon artist brushes hold
their shape and maintain their fine points under the toughest conditions.
Thunderon®
Thunderon® is an acrylic fiber that has been chemically
bonded with a layer of copper sulfide. This outer layer becomes a part of the
host fiber itself, which precludes the 'flaking' problem experienced by other
conductive fibers. The fiber diameter is as fine as 0.004 cm (0.0015") and
its conductive layer is a super thin 300-1,000A (angstroms). It has electrical
specific resistance of 101 - 102 Ω /cm.
Gordon Brush is well stocked with standard
brushes using these materials. However, if you don't see what you are looking
for, we can always customize a brush for you.
If a brush exists, we have it…If it doesn't,
we'll make it!
