Water Soluble Mandrel
Product Introduction
WSM-1014, Water Soluble Mandrel, is a white powder water-soluble mandrel. It is suitable for the formation of special-shaped components. The operation process is simple that it can be casted after adding a certain proportion of water and mixing them well. The mandrel after heating has high strength, low thermal expansion coefficient and good heat resistance that can be used in common thermosetting or thermoplastic composites.
