Ceramic molding methods that use binders include press molding, tape molding, casting molding, injection molding, and extrusion molding.
JMR can be used with a wide variety of inorganic materials and molding methods, and its properties are especially beneficial for molding oxidized inorganic materials, such as alumina and zirconia. |

*1 Degree of polymerization 600, degree of hydrolysis 88 mol%
*2 Type B Rotating Viscometer was used (20 rpm).
*3 Set the spray dry temperature 50ºC to 100ºC lower than that for general PVOH.
*4 Measured from the cyclone collection amount.
*5 [Photograph] Refers to "granules...Ease of Crushing"
*6 Increasing the concentration causes the formation of many dimples. |
