Static Dissipative Plate

Polstar Static Dissipative Plate (PSDP) is made of clear plastic sheet coated on both sides providing semi-permanent surface resistance of <10e9 ohm, which will help to eliminate static electricity effectively. PSDP is ideal for the speedy decay of static charge without the creation of harmful arcing to the surface of vulnerable components. PSDP satisfies electrical and optical requirements providing superior abrasion, non-scratchable surface and chemical resistance.

PSDP is available with Polycarbonate (high temperature performance, fire resistance and outstanding impact resistance), PMMA (strong surface hardness and optimum clarity), PVC (good chemical resistance) and Aluminum Composition Panel to meet wide applications in each industry.

The new designed PSDP series are also applicable for the special applications of bending and bonding (Polycarbonate is not suitable for the bonding applications) without any crack on the surface and changing the surface resistance after bending.

PSDP is made in Korea. Its manufacturing site and R&D Center are located in Korea as well, those are certified to ISO 9001, Quality Management System and ISO 14001, Environmental Management System. We also have facilities for product development, technical service and quality monitoring and after-sales service.

Maintenance, Handling, Caution

  • Recommendable storage conditions : less than 30℃, RH40-60%
  • To avoid scratches on the surface, remove the protective film after PSDP has been machined.
  • It is recommendable to have trials with test specimen to determine optimum settings before cutting or modification.
  • Static dissipative coating must be removed from the surface to be glued.
  • Isopropyl Alcohol (IPA) or alcohol based cleaning liquid is recommendable for cleaning.
  • PSDP is not required to be cleaned with antistatic plastic cleaners.
  • Loss of static dissipative performance will occur if excess scratching is concentrated in a particular area.
  • If PSDP is treated with a polishing machine, the performance of static dissipative coating cannot be guaranteed.
