Essemplex

Essemplex is a fully formable, thermoplastic shape memory polymer (SMP) resin. Like other thermoplastics, the polymer is easily processed into memory shapes using conventional methods. Once formed, the polymer exhibits shape memory properties.

CRG Industries offers two versions of Essemplex, with SMP activation temperatures of 34°C and 43°C. The material will be supplied in pelleted form. The SMP heating and reshaping process can be repeated without loss of the memory shape or degradation of the material.

Features and Benefits

   • Reconfigurable
   • Formable
   • Versatile design options
   • Compatible with conventional processing
      methods such as:
      o Injection molding
      o Thermoforming
      o Extrusion

Temperature Properties
Above melt temperature (Tm) • Can be molded and cooled to
   hold nearly any memory
   shape
• Can be melted and remolded
   into a new memory shape
Above activation temperature (Tg) • Can be shaped and cooled
   into a new shape if
   constrained
• Will return to original memory
   shape if left unconstrained
Below Tg • Remains rigid in the desired
   shape
