Product Data Sheets



There are three types of HYTAC materials (full descriptions on our products pages):

1. Thermoset Syntactic Foam (also referred to as Epoxy Syntactic, Epoxy Composite, 350 or 450) is a homogeneous blend of microspheres and a special epoxy binder system resulting in a low thermal conductivity plug.

2. Copolymer Thermoset Syntactic Foam is formulated to balance plug performance with easy machining/polishing without dust and a longer lasting, more durable plug.

3. Thermoplastic Syntactic Foam is the most durable plug material and combines the benefits of syntactic foam with long life even in the most abusive production environments. It machines in large shavings with no dust and provides excellent material distribution in a mold. 


METAPOR® is a composite material consisting of two major components. Different granules, such as aluminium or ceramic materials, and binders are currently used in thermoforming tools. The material is air-permeable over the entire surface, due to its micro-porous structure. In contrast to sintered materials, the pores are not closed off after machining. The numerous advantages are useful in the thermoforming industry as well as for vacuum clamping and air cushion devices. Design flexibility is enhanced because micro-vents are an integral part of the complete surface. The material‘s inherent properties eliminate the need to design and manufacture complex venting systems.

Tooling Board Products

CTB, Rampf® and Ren Shape® tooling and modeling board. Vacuum formers and thermoformers use these products for prototype and low volume production molds when forming in applications where metal molds do not make sense due to time or cost considerations. CMT can help in selecting the proper board material for specific forming applications considering factors such as surface quality, ease in machining, tool durability, and forming temperature. See our Comparison List for details on all available tool board products.
