Vacuum forming tooling board

REN Shape 5008 is a tooling board specifically designed for use in vacuum forming. It is designed for use up to 250F and is well-suited for building vacuum forming molds as well as master models, lay-up tools for pre-preg curing and other heat resistant tooling. This moderate density epoxy system features a low coefficient of thermal expansion for outstanding accuracy and dimensional stability.

REN Shape 5008 also offers the following advantages:

  • Good machinability
  • Superior edge definition and dimensional stability
  • Outstanding surface finish
