At Melrose, we believe in the power of knowledge sharing through our “Sharing is Caring” initiative. We use industry-leading materials for customer projects to ensure quality and durability over the long term. This article spotlights ISOLOSS™ LS foams, manufactured by Aearo Technologies LLC, to share valuable insights for your engineering needs.

What are ISOLOSS™ LS Polyether Polyurethane Foams?

ISOLOSS™ LS Foams are a superior material choice composed of polyether polyurethane foams. This formulation offers significant advantages over traditional polyester polyurethane foams, particularly in terms of durability and performance in challenging environments. The material composition of these foams provides a solution for gasketing, cushioning, energy control, and sealing challenges.

The microcellular, open-cell structure ensures low compression design, meaning the shape stays intact even after prolonged pressure or impact. These foams are available in various densities such as LS-10xxLM, LS-15xx, LS-20xx, and LS-25xx. These variants make the material ideal for engineers to use for specific application requirements. You can use the datasheet to access more technical information about the typical properties of these variants.

With features such as excellent shock absorption, vibration isolation, and low outgassing, these foams provide a reliable and versatile solution for various engineering challenges.
