Heat shrink tubing waterproof seal
2:1 shrink ratio
Flame retardant, inner adhesive self extinguished
Super sealing against water, moisture or other contaminants
Continuous operating temperature: -55℃~ 125℃
Shrink temperature: 120℃
Adhesive lined heat shrink tubing, designed to insulate and seal electrical and mechanical components against water and moisture, applications include general electrical insulation, mechanical protection and cable and harness bundling. Adhesive lined heat shrink tubing is widely used in marine, automotive, electrical and general industrial industries.
What are some important specifications to consider when choosing heat shrink tubing?
The maximum diameter of your cable bundle and the temperature range required by your application are both important factors to consider when choosing heat shrink tubing.
If the wire or cable OD changes drastically, the heat shrink ratio is also an important spec to consider so that you get the correct fit for your heat shrinkable tubing.
What makes heat shrink tubing shrinkable?
You've probably noticed that most plastics you come in contact with won't just shrink down if they're heated – so what makes heat shrink tubing different? The answer is cross-linking, the process of exposing a polymer to radiation in order to create covalent bonds between that polymer's atoms. it was discovered that radiation was capable of altering the molecular structure of certain plastics so that they wouldn't melt or develop a flowing consistency, no matter what temperatures they were exposed to. Covalent bonds also give polymers plastic memory, which means that once a polymer has been cross-linked and stretched into an expanded shape, it will automatically shrink back to its original dimensions when a certain amount of heat is applied.
