SeaFlex® Flexible Thermoplastic Sheet

SeaFlex® is our second generation of flexible materials for orthotics and prosthetics. 

SeaFlex® is lighter in weight than any other flexible material currently available for P & O. A common problem with materials containing low density polyethylene is discolouration after a period of time being worn. This discolouration has a number of causes, the main one being exposure to human skin oil. SeaFlex® is much, much more resistant to discolouration and over 13 years of use has proven the fact that SeaFlex® does not discolour very easily. To give more choice to the amputee for comfort levels, SeaFlex® is produced in three distinct grades of flexibility, 100 (very flexible), 200 (flexible) and 300 (stiff).

The three grades of flexibility also provides more choice for use in the manufacture of various orthotic devices. SeaFlex® is used to manufacture SMO’s, wrist splints, protective helmets, neck braces, and body jackets.

SeaFlex® is a very stable, forgiving material when being moulded, and exhibits no shrinkage after it has been moulded.
