Veriflex® is a two-part, fully formable, thermoset shape memory polymer (SMP) resin system. Cured Veriflex has unique “shape memory” properties. When heated above its activation temperature (Tg), Veriflex changes from a rigid plastic to a flexible elastomer. In its elastic state, it can be twisted, pulled, bent, and stretched, reaching up to 200% elongation. If cooled while constrained in this new shape, the polymer hardens and can maintain its new shape. When heated, unconstrained, above its Tg, this polymer returns to the shape in which it was cured. This process can be repeated indefinitely without loss of the memory shape or degradation of the material. Standard Veriflex resin is engineered with a Tg of 62 °C (144 °F). Uncured Veriflex resin has a low viscosity that makes it easy for RTM or VARTM processing and composite fabrication. Typical applications include customizable and reusable molds, toys, architectural applications, furniture, deployment mechanisms, containers, shipping and packaging, thermal sensors, and actuators. |
