According to the company, the patent covers a specially formulated polypropylene compound using proprietary non-halogent flame retardant technology that it says is ideally suited for injection molding recyclable plastic computer housings and constructions boards.
JJI Technologies (Painesville, OH) is a developer and supplier of flame retardants with its focus on environmentally friendly grades of these additives. The European patent is was granted for the material for fully recylable computer housings, EP2045288, could grab the attention of OEMs that in Europe must follow the Waste Electrical Electronic Equipment (WEEE) directives. These directives mandate that suppliers of electronic devices sold in Europe must finance the cost of treating and recovering the types of products they import, rebrand or manufacture. The products also must meet Restriction of Hazardous Substances (RoHS) directives that limit the use of brominated and halogenated flame retardants, among other substances, in some products.
JJI reports there have been assembled prototypes of the housings and the material has been independently tested to confirm that the flame retardant material may be recycled at least five times without loss of the UL94 V0 flammability standard with minimal impact on physical properties....
