ASA provides a multilayer elastomeric system  to replace the conventional rigid foam on this low process pipe work.  This kind of foam combine in a single material the key performance qualities that are traditionally only achieved through the labor-intensive combinations of several other materials (e.g. rigid foams combined with vapor retarders and contraction joints). They combine low thermal conductivity, in a light-weight (low density) foam that remains flexible at low temperatures. This flexibility provides a system that inherently absorbs vibrations and iimpact, to provide a robust and low-maintenance solutions to the insulation of cryogenic pipelines, vessels and equipment.
