Composition for lubricant content polyoxymethylene formation, the use and formation item

摘要

The polyoxymethylene which adds the lubricant blend which from aliphatic ester and the polyethylene wax is formed when it compares with the polyoxymethylene which includes only aliphatic ester, improves in - feed behavior to the injection molding machine without substantially changing tribology behavior. Also strength of the weld line of the formation item improves. The composition for formation seems that runs on the hard material, it is used for the formation item of the optional type whose tribology efficiency request is high.
