Medical grade heat shrinkable tubing made of medical grade polyolefin with a 2:1 shrink ratio has a thicker wall thickness value compared to MT2 medical tubing, which can meet more stringent electrical insulation requirements and anti-wear mechanical properties, and is often designed for the insulation protection of laparoscopic medical instruments.
