Disintegrating Mold Material (DMM)
DMM was created for the aircraft and plastics industries for the formation of mandrels and cores for the production of plastic ductwork, filament winding, weldments, and other similar parts. The Disintegrating Mold Material™ (DMM™) disintegrates easily upon introduction into the disintegrating solution to a lesser degree in plain water. It has the ability to withstand rapid heating or cooling without cracking or breaking due to its very low thermal expansion or contraction in the temperature range of 0 to 600°F. Because of its extremely low-setting expansion, the problem of removal from dies is minimized.
• Material disintegrates easily
• Very low thermal expansion
• Easy removal from dies
