Syntac® TMax

Syntac® TMax

Syntac® TMax is a high performance syntactic foam. A rigid, high strength composite of epoxy resin and hollow glass microspheres. Syntac® TMax maintains its strength right up to the maximum running temperature and exhibits reduced plug build up while operating at these high temperatures. In addition, Syntac® TMax also exhibits excellent abrasion resistant properties coupled with a maximum running temperature of 450 °F / 232 °C. Syntac® TMax was developed to meet and exceed the distinctive expectations of our thermoforming customers.
