Product Describe：  The electronic grade copper oxide is based on 100%electronic copper powder as raw material by advanced and no pollution production process produced. Has the followingcharacteristics: 1, high content (CuO content of 99.5%). 2,fewer impurities (in line with the EU REACH standard SGSreport). 3, strong activity (ultrafine particles of 400 orders to ensure product activity). 4, the quality is stable (100%copper powder as raw material and non pollution productionprocess to ensure product consistency). 5, price concessions (than the imports of copper oxide has a higher price).
Packaging: 50 kg / barrel.
Storage: keep in a cool and dry.
