| DESCRIPTION Cosmic 224 is a dacron filled, general purpose diallyl ortho phthalate molding compound which is supplied in a flake form. It molds easily in standard compression or transfer equipment. FEATURES It has excellent electrical properties with an impact strength considerably higher than orlon filled material. A special processing enables 224 to retain its excellent volume and surface resistance after prolonged exposure to elevated temperature and 100% humidity. APPLICATIONS The inherent strength of dacron fibers makes this compound excellent for applications requiring high physical and/or electrical properties.&& |
