Characteristics
:
• Brushes minimize static charge generation and remove electrostatic charges to
ground when held by grounded personnel
• Dissipative polypropylene black handles remove charges when grounded
• Available in two kinds of bristles - semi fine, firm
• Semi-fine bristles are ideal for chemical and electronics applications
• Firm bristles are mainly for electronics, especially circuit boards
• Conductive handle’s ESD properties are not effected by humidity as are wooden
handle brushes
• Conductive copper based nylon bristles with hog hair and two other natural fibers.
• Volume Resistance of conductive fibers:
1 x 103 to < 1 x 105 ohms per ANSI/ESD STM11.12
• Volume Resistance of dissipative handle:
1 x 104 to < 1 x 1011 ohms per ANSI/ESD STM11.12

ESD Handbook TR20.20 Table 1 lists under Typical Static Electricity Sources
“Brushes (camel/pig hair and synthetic bristles).” “It should be understood
that any object, item, material or person could be a source of static electricity
in the work environment. Removal of unnecessary nonconductors, replacing
nonconductive materials with dissipative or conductive materials and grounding
all conductors are the principle methods of controlling static electricity in the
workplace, regardless of the activity.” (TR 20.20 section 2.4)

Synthetic vs. Natural Bristles
Synthetic bristles can easily become charged with static in standard humidity conditions.
Natural hair usually builds static in areas of low humidity, but due to the conductive fibers in our brushes,
this problem does not take effect.
Generally speaking, once the conductive yarn is added to the bristles, it neutralizes the possibility of static
build up caused by the natural hair.
