CMT Materials CTB 44 Composite Toolboard High Temperature
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	CTB-44 is manufactured by CMT Materials for a wide variety of vacuum forming applications. It is suitable for use up to 2500F (1210C). 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 Applications: CTB-44 is an excellent choice for constructing forming tools, master models, fixturing and other heat resistant applications. It may also be used for composite fabrication in pre-preg and autoclave cure, wet lay-up, vacuum infusion and other composite processes. Information Provided by CMT Materials, Inc.
