There are two kinds of heat shrink tubing of adhesive lined heat shrink tubing . One kind is dual wall heat shrink tubing , we named it DHST , another is medium wall heat shrink tubing , we named it MHST .

The difference between them :

  1. The wall thickness , medium wall heat shrink tubing is more thick then dual wall heat shrink tubing .
  2. Glue coating process is different . The glue in dual wall heat shrink tubing was coated at the same time as produce heat shrink tubing . The glue inside medium wall heat shrink tubing was coated after the tubing produced .
  3. Dual wall heat shrink tubing
    Suitable for electronic equipment wiring waterproof, air leakage, water pump and submersible pump wiring waterproof, underwater lighting, automotive tubing, senior wire harness and other occasions .
  4. Medium wall heat shrink tubing
    Suitable for small diameter steel pipe, stainless steel and other hard objects of external corrosion, such as sound detection pipe, concrete buried steel pipe connection waterproof, anticorrosive

As the pictures above , there are two methods to coat glue in medium wall heat shrink tubing . Screw glue lined and Straight glue lined .
