This video demonstrates how to use Vac-Master 25 & 50 in making tools for vacuum forming. Vac-Master 50 contains over 50% aluminum and has great heat transfer for reproduced production cycles in vacuum forming, RIM, and foam. Machinability and polishability are excellent. Vac-Master 50 also has a high heat deflection. Vac-Master 25 is a great general-purpose tooling resin for less demanding applications.
