Product description

TenCate Amspand ES72A-2 is a 125°C (257°F) curing expanding unsupported epoxy resin film incorporating low density expanding microballons, and is supplied in sheets (625mm x 400mm). TenCate Amspand ES72A-2 expands using a closed cell process ensuring complete homogeneous cell structure, the density/strength may be altered simply by changing cure pressure or limiting the volume available for expansion, the material is capable of expanding up to 650%. TenCate Amspand ES72A-2 is available in a variety of thicknesses down to 1mm and can be easily contoured and shaped. TenCate Amspand ES72A-2 offers reduced processing, a one shot cure, the ability to anchor inserts or fastenings and increases the opportunity to consider light weight, thin walled composite structures.
