Polyurethane (PU) Foam Insert
Custom molded polyurethane (PU) foam inserts are the perfect choice for protecting your products against damage due to its high shock absorbent characteristic while creating a luxury look and feel. In addition, PU foam is an excellent choice for its lightweight and compressible (easy to store) nature.
- Lightweight and compressible for easy storage
- Shock absorbent material
- Custom-molded to your product
Overview
PU, short for polyurethane, is a kind of open-cell foam material that is lightweight and more compressible than other foam alternatives, making it very versatile in many packaging applications. In addition, due to its soft characteristic, PU foam has high shock absorbency, turning this material a standard selection among many industries looking for added protection. Our polyurethane foam inserts are available in a wide range of densities and colors.

Foam Fabrication Methods
Water Jet Cut
Process of cutting material with a high-pressure jet of water—ideal for producing extremely accurate shapes.
Knife/Router Cut
Process of cutting material using a router bit or knife—ideal for prototyping due to its imprecise finish.
Die Cut
Process of cutting material using a series of dies—ideal for simple two-dimensional cutouts.
Wire Cut
Process of cutting material using a heated metal wire to melt and vaporize foam to create clean, crisp cuts.
Laser Cut
Process of cutting material using a high-power laser beam to cut and vaporize foam for smooth edges.
