The outer layer is a semi-rigid crosslinked polyolefin material as described in IEC 684-3-211, type 2. The inner layer is a substantially non-crosslinked polyolefin that flows and fuses during the shrinkage process to provide a seal. Sleeving of this type is normally available in bore sizes up to 25 mm.
