What is LS Polyurethane Foam Used For

Whether the application is for gasketing, cushioning, sealing, vibration  management, or acoustics control — LS Polyurethane Foams provide  an all purpose solution across many industries. LS Foams are microcellular  open cell polyurethane foams with a low compression set to maintain  the components original fit, form, and function throughout the product's  lifecycle. The highly shock absorbent, and flame and chemical resistant  foams provide strength and longevity in extreme environments with  a wide temperature range.

LS Foams are low compression set, high density urethane foams for gasketing, sealing and damping applications, and include a variety of thicknesses and densities to meet most application requirements.

Low Compression Set

The foam rebounds to maintain the same fit, form, and function throughout the product's lifecycle.


Highly shock absorbent, and flame and chemical resistant foams provide strength and longevity in extreme environments and temperatures.

Variety of Densities & Thicknesses

A unique combination of design features allow for custom made solutions for different applications.

Energy Control

From sensitive electronics to earth shaking heavy equipment, protect critical equipment from impact, shock, and vibration.

Gasketing & Sealing

UL gasket & sealing rated and pairs well with 3M™ Laminating Adhesives.

Cushioning & Support

Soft and supportive foam that conforms to the design and fills gaps to protect equipment.
