AI Technical Summary

Problems solved by technology

It provides an ultra-low resistance polymer conductive product by adding high-performance conductive carbon black and additives, and using a special modified manufacturing process. Its disadvantages are: the content of conductive carbon black is too high, the processing technology is complicated, and the production efficiency is low. , the toughness of the product is not high, and the fracture elongation of the material is less than 100%

Its disadvantages are: using nano-graphite as conductive filler, the conductivity is not high, the volume resistivity is relatively large, the production adopts twin-roll mixing processing, the process is backward, the quality stability is poor, and the efficiency is low

It uses three grades of POE as raw materials, thermoplastic rubber as a modifier, and adds 25 to 30 parts of superconducting carbon black, dispersant, lubricant, rheological agent and other additives to make high-conductivity plastic sheathing materials. Good electrical conductivity and tensile properties, its disadvantages are: the manufacturing process is complicated, the product quality between batches is not easy to control, and it is not easy to produce in large quantities; The internal copper core protection has adverse effects; the thermoplastic rubber SEBS (YH-403) added to the formula is a polymer with poor fluidity. Although a certain amount of rheological agent and lubricant is added, the flow of the material sex is still bad
