Characteristics:

• Brushes minimise static charge generation and remove electrostatic charges to ground when held by grounded personnel
• Dissipative polypropylene black handles are able to remove charges to ground
• Volume Resistance of conductive fibres: 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
• Two kinds of bristles: soft and hard
• Soft bristles are ideal for chemical and electronics applications
• Hard bristles are mainly for electronics, especially circuit boards

Soft bristles are made of conductive yarn and horse hair. Hard bristles are made of conductive yarn, pig hair and horse hair. Generally speaking, once the conductive yarn is added to the bristles, it neutralises the possibility of static build-up caused by the natural hair. 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 fibres in our brushes, this problem does not take effect.
