Which insulation type is described as 'FOAM (single expanded plastic)' in ICEA classifications?

In ICEA classifications, insulation types describe how the plastic around the conductor is built. FOAM (single expanded plastic) identifies a foam insulation with a single layer formed by expansion during extrusion. That creates air pockets, yielding lower density and a lower dielectric constant, which improves insulation performance and flexibility compared with solid plastic. This specific label distinguishes it from other constructions: PIC is solid plastic insulation without foam, DEPIC implies dual expanded plastic (two foam layers or a combined structure), and PVC denotes solid PVC insulation with no foam. Therefore, the insulation type described as "FOAM (single expanded plastic)" is the foam-in-single-layer classification.
