ISOLOSS™ LS Polyurethane
(Poron Equivalent)
What is LS Polyurethane Foam Used For
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.
Durable
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.
LS part Number Designation
Example: LS-1025LM
LS - Material Family
10 - Density (ft/lb3 or lcf)
25 - Thickness (hundreds of an inch)
LM/HM - Low/High Modulus
If no modulus rating is listed the material is considered a standard modulus/stiffness for that density.
