- Product Overview
The energy from the constant vibration and heat of running parts in machinery and equipment can cause a lot of wear and tear. In addition to being highly shock absorbent, these durable foams also provide flame and chemical resistance in extreme environments. 3M™ ISOLOSS™ LS foams provide strength and longevity in applications, even in temperatures ranging from -40°F (-40°C) to 225°F (107.2°C).

Technical Details & Test Data
- When is LS™ Foam Not Recommended?
Despite the microcellular structure which appears to be closed cell, LS is an open cell foam. Outdoor enclosures that are subjected to rain and temperature extremes may not be sealed properly with LS gaskets. Conditions where LS may be flexed or repeatedly compressed and relaxed in standing water may cause water to be wicked into the gasket. Temperatures below -20°F will cause LS to stiffen, and LS is not recommended for constant temperatures above 158°F. Outdoor conditions may be better served with silicone sponge or high grade neoprene or EPDM sponge materials.
