Polyurethane (PU) IsoGel®

A visco-elastic polyurethane material with 3-axis liquid-like deformation that helps absorb pressure while having memory properties like that of a solid in order to rebound to its original shape and provide support where needed.

 

Pittsburgh Plastics Manufacturing’s PU IsoGel® is a cross-linked system that maintains its shape while being stretched or compressed in any direction. The molecular structure provides shock absorption through a fluid-like slip of the cross-link chains; however as the chains are long and dispersed through the material, IsoGel® can support a large amount of weight (load) without bottoming out. The unique cross-link structure provides high elasticity with high tensile strength.


The fluid-like properties also allow for even weight distribution and vibration dampening. Even though the gel has properties like that of a fluid, it will not leak or run. Its exceptional soft cushioning properties allow for shear force reduction to the user’s skin and body.

PU IsoGel® polymer has been tested and confirmed as stable, non-toxic, and non-irritating according to ISO 10993 biocompatibility tests parts 5, 10, 11, and 12. PU IsoGel® does not include Latex, Silicone, or Plasticizers.

 

The polyurethane IsoGel® system provides high thermal stability with its low thermal conductivity by acting like an insulator. Similarly, IsoGel® is electrically non-conductive, x-ray translucent, and appropriate for use in operating rooms and magnetic resonance imaging (MRI) machines. The unique chemical stability of this IsoGel® will not harden over time and is resistant to oils and greases.

 

PU IsoGel® can be molded into various shapes or be used as gel filler inside of cushions. It can be manufactured to a wide scale of durometers from the Shore A scale to below the Shore OOO range and into cone penetration levels. PU IsoGel® can be customized to almost any color including but not limited to clear, white, black, blue, red, yellow, and even glow in the dark! 

*Note: color availability is product dependent

 

Multiple additives and formulations of the base polyurethane IsoGel® system allow for the following variations of the IsoGel® product:

 

  • SSCP (Super Soft Cone Penetration) IsoGel®: Cone Penetration depth of 200 mm to 10 “OOO” durometer
  • UHR (Ultra High Resiliency) IsoGel®: 10 “OOO” to 80 “OO” durometer
  • ULR (Ultra Low Resiliency) IsoGel®: 10 “OOO” to 80 “OO” durometer
