Trelleborg TC760X is a medium temperature, low density syntactic epoxy tooling board designed to act as a more durable/higher temperature master molding base or facilitate direct-to-part tooling.
TC760X is a superior quality tooling board, offering crack resistance and dust free machining.
Maintains its shape at elevated temperatures, increased durability, no cracking, reduced edge chipping in machining
Direct-to-part tooling with standard 120 °C prepregs
Reduced rework on molded component surfaces due to superior tool surface quality
Reducing surface preparation time prior to sealing/Reduced sealant usage as compared to standard epoxy boards
TC760X is available in a standard board size of 24” x 60” at the following thickness: 2”, 3”, 4” and 6”
TC760X can be sawn using carbide or diamond coated saw blades or cutting wheels
Large patterns can be constructed from boards using the appropriately selected epoxy adhesive system. Trelleborg adhesive system 551A/B is recommended. The adhesive system must offer adequate pot life and be capable of meeting the mechanical and thermal properties of the tooling board.
