	Wafer Combs Wafer combs made of Semitron ESd 225 eliminate transfer equipment discharge problems that cause millions of dollars in lost wafers every year. (Prior materials: Nylon, Standard Acetal)
	Handling Trays Trays manufactured from SemitronTM ESd 410C dissipate static charges reliably and are dimensionally stable. (Prior materials: PPS, PEEK, Vespel* PI)

Static dissipative products are designed for use where electrical discharge in operation is a problem. They are commonly used for sensitive electronic components including: integrated circuits, hard disk drives and circuit boards. These materials are also an excellent choice for material handling applications, and components in high speed electronic printing and reproducing equipment.
