ST-Poly is a true breakthrough in materials science.
ST-Poly is a unique "conductive polymer plating" that can be attached to almost any base plastic material. It is ideal for both formed and molded trays.
ST-Poly provides various industries affected by ESD problems with a clean, low-cost transparent ESD solution: ST-Poly contains no carbon, no metal, no corrosive agents. It is very clean and can be used in the toughest cleanrooms AND be rewashed in either ultrasonic DI or IPA without any degradation or contamination.
It can replace expensive contaminating non-transparent vacuum formed and molded trays with a low cost, clean and transparent recyclable solution. Never has a truly dissipative/conductive material been transparent to the point of barcode scannability until ST-Poly. You can see ST-Poly(on the left) vs carbon coated to the right and the difference is CLEAR.

How it works
ST-Poly technology coats a molded (or extruded) product with a conductive monomer having an electronic conjugated system. A uniform conductive polymer film is produced through a polymerization reaction, and is then applied. The new method achieves a cleanliness level that can be used in information-related equipment and cuts costs by about 1/2 compared to existing methods.
Currently available anti-electrostatic measures for molded products include the application of a paint containing conductive fillers, such as metal granules and carbon, or a conductive material such as a surfactant. However, these methods are expensive and carbon fall-out results in contamination. Therefore, they have particularly been problematic for components used in information-related equipment, such as HDD components, which require a high level of cleanliness.
