Electrostatic influences

The increasing level of electronic equipment used in many sectors of industry have resulted in a huge rise in the importance of antistatic and discharging materials. Electrostatic charges not only have an important role to play in protecting people - equipment and materials also need to be protected. This makes the use of electrically conductive or antistatic materials essential if the high voltage
pulses that arise in the rapid discharge of electrostatically charged materials are to
be prevented through controlled discharges.

We offer an extensive range of materials for this sector with an expanded range of stock products.
