Components made of polyetherimide (PEI) and polyphenylensulfide (PPS) are characterized by their good mechanical, electrical and thermal properties and have therefore the potential to substitute metal parts. Filled with glass fibers those properties can be further improved. Processing is possible through injection molding. Complex structures can therefore be manufactured in high volumes at low prices. But only with a metallic top coat the substitution of metallic components becomes perfect. Biconex has developed a simple, solely chemical based process - chromium VI-free of course - to coat complex components made of polyetherimide with metals, i.e. nickel phosphorous alloys with high wear resistances.
Metal coated PPS parts have in spite of their low weight not only the look and feel of metal, but also their characteristic sound. Especially for visible elements like housings they are a perfect high value metal replacement.
