4Dresyn TF-HV1, Tough & Foldable High Viscosity 4D resin
Product description
4Dresyn® TF-HV1 is a tough and foldable high viscosity 4D photopolymer designed to exhibit temperature-dependent mechanical behavior, transitioning from rigid below 0 °C to tough and flexible above 15 °C. It is intended to be combined with other 4Dresyn® materials to achieve customized 4D performance and programmed mechanical response.
Application framework
