CTB-44 Toolboard
High temperature, long life and easily machined for smooth surface finishes
CTB-44 is manufactured by CMT Materials for a wide variety of vacuum forming applications. It is suitable for use up to 250F (121C). CTB-44 utilizes a copolymer base material and smaller cell structure than most boards, providing improved mechanical properties and a smoother surface finish.
- Excellent machinability
- Superior edge definition
- Good dimensional stability
- Outstanding surface finish
