Essemplex

CRG Industries, LLC

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

Please call or e-mail us for more information about Essemplex or to discuss your application.

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

Possible Applications

Custom molds
Toys
Furniture
Architectural elements
Smart fasteners
Switchable mounting brackets
