ESS-TOOL™ 705 is a new class of tooling board.  By using a thermoplastic syntactic structure, 705 triples flexural toughness and impact resistance while maintaining other properties critical to tooling materials.  705 is easily machined and provides excellent edge definition. It is engineered for use in applications where durability is of much greater significance than CTE. ESS-TOOL may be bonded using adhesives and techniques specifically designed for adhesion of thermoplastic materials.
