ESD & CONDUCORE
ESD – electrostatic discharge i.e. a flow of electricity between two differently- charged objects.
Static electricity occurs when two objects are rubbed together and pushed away.
Examples of static electricity (build-up of electric charge)
- moving plastic items,
- rubbing parts of clothes which are prone to build-up of static charge,
- walking on a synthetic flooring
- extension of stretchable bands,
- brushing your hair with a plastic comb,
- rubbing plastic items …
Bringing two differently-charged items into contact can cause a flashover (spark) from the negatively charged conductor/item to the positively charged one.
Static electricity is characterised by high voltage, i.e. above 10kV, which is common in the working environment; however, it can reach up to 30kV when humidity is below 20%.
So as to eliminate this phenomenon negatively affecting devices sensitive to ESD, earthing techniques are applied, starting from flooring, tables and other workshop devices, as well as personal protection equipment suitable for dissipating and draining electrostatic charge.
ESD earthing equipment often requires an individual approach both at the stage of engineering and manufacturing of ESD protection equipment, taking into account individual solutions suitable for certain location and issue concerned.
Taking this approach, we can design and manufacture ESD parts using our proprietary and patented CONDUCORE technology for manufacturing dissipative and conductive composite parts.
CONDUCORE technology offers great opportunities for manufacturing ESD composites exhibiting excellent mechanical and strength properties. Possibility to choose desired electrostatic properties of composite material is a great advantage. This is achieved through the selection and adaptation of raw materials to the desired conductive or dissipative properties, as early as at the stage of [Uwaga tłumacza: brak dalszej części zdania]
EPA equipment may include, inter alia, the following elements:
- workshop equipment,
- parts of machines,
- transportation trays and pallets,
- company handling equipment,
- workshop tables, shelves, racks....
CONDUCORE technology allows for utilisation of excellent strength and anti-static properties of composites, as well as for flexible selection of materials such as conductive materials, static-dissipative materials or insulative materials.
Our products may come with the following electrical properties:
- Conductive materials
Low electrical resistance (less than 10^5 Ω); easily allow the charges to flow to ground.
Conductive materials include, inter alia, carbon, metals, conductive plastics, human sweat…
- Static-dissipative materials
Dissipative materials have a surface resistivity ranging between 10^5 and 10^12 Ω. For these materials charges flow to the ground more slowly than with conductive materials and potential negative effect is reduced.
- Insulative materials
Insulative materials are defined as those having a surface resistivity exceeding 10^12 Ω.
Insulative materials are difficult to ground and static charges remain in place on these materials for a very long time.
Insulative materials include: glass, rubber, dielectric materials, air…
Majority of ESD-resistant components can be made of composites.
