Northfoam® 33, Northfoam® 140 & Northfoam® 170.



Closed cell polyethylene foam

Density 33, 140 and 170 Kg/m³

Northfoam® 33 is a lightweight padding material

Northfoam® 170 is a fairly dense foam, with a relatively smooth surface finish, making it suitable for a number of applications in orthotics and prosthetics. Northfoam® 170 is used in prosthetics mainly for BK socket liners, and in orthotics for foot orthotics for padding and lining purposes.

Northfoam® 140 is a slightly softer grade of Northfoam® 170, and is only available in a SilverShield® antimicrobial grade, flesh colour. Northfoam® 140 is suitable for manufacturing BK socket liners, and foot orthotics.

Northfoam® 33 is an extruded foam, which provides a skin on both surfaces of the material, no matter the thickness. This skin leaves no exposed “cells”, which capture dirt and microbes, providing a wipe clean surface. With a density of just 33kg/m3 , Northfoam® 33 has good cushioning properties. The main use is in orthotic applications for padding and lining purposes
