Zusammenfassung:	PURPOSE: Structural foam plastic having electrostatic dissipative properties, a movable cart embodying the same, and a method of using the same are provided to prevent unexpected breakage of electrical parts caused by an electrostatic charge. CONSTITUTION: An electrostatic dissipative cart comprises a cart body(10) which is grounded and has a resistivity in the range of 10¬6 ohms/square and 10¬9 ohms/square as measured between ground and substantially all exterior points on the cart body, and at least one rolling member(14) supporting the cart body. The cart body includes at least one electrostatic dissipative material. The cart body is formed substantially entirely of electrostatic dissipative material. 정전기 소산 재료로 만들어진 사출 성형 이동성 보수 카트는 10옴/스퀘어 내지 10옴/스퀘어 범위의 저항을 영구히 일관되게 나타내고 제어된다. 카트는 정전기 소산 재료를 포함하는 구조적 발포 플라스틱으로 만들어진다. 부품을 운반하는 카트를 통과하는 정전기 전하에 의한 불의의 전자 부품의 파손은 카트가 정전기 소산 재료로 만들어짐으로써 방지된다.
