Polstar Static Dissipative Plate (PSDP) features a special ESD hard-coating on both surfaces, providing a semi- permanent surface resistance of <10e9 ohms, effectively eliminating static electricity. PSDP is ideal for rapidly dissipating static charges without causing harmful arcing on the surface of vulnerable components. PSDP meets electrical and optical requirements while offering superior abrasion resistance, a non-scratchable surface, and chemical resistance. PSDP is available in Polycarbonate (for high-temperature performance, fire resistance, and outstanding impact resistance), PMMA (offering high pencil hardness and excellent clarity), PVC (with excellent chemical resistance), and Aluminum Composite Panels, catering to a wide range of applications across various industries. The newly designed PSDP series is also available for specialized bending and bonding applications (please note that Polycarbonate is not suitable for bonding) without developing surface cracks and without altering surface resistance after the bending process.

Maintenance, Handling, Caution
- Recommendable storage conditions: less than 30℃, RH 40 ~ 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.
