The global market for heat shrink tubing and materials is at approximately $1.8 billion. By 2027, this number is projected to reach $2.6 billion. However, we know that ultimately the value of heat shrink boils down to how it benefits and makes your life easier. This article will cover the basics of heat shrink followed by four of its applications spanning numerous industries.
Heat shrink is a plastic film that can wrap around any wire or object no matter its size. The capabilities of heat shrink were discovered after World War II when they found that radiation was capable of modifying the molecular structure of certain plastics. Paul Cook, the founder of Raychem, used radiation chemistry to create covalent bonds between a polymer’s atoms. This explains why plastic can be cross-linked and stretched into an expanded form that once heat is applied, it automatically shrinks back to its original form (referred to as plastic memory).
These versatile features of heat shrink make it ideal for these four (among many others) uses:
- Protects Equipment and Valuables: Heat shrink ensures a watertight seal. This protects the enclosed equipment/wires from being damaged by dust, dirt, or moisture
- Conserves Space: Heat shrink is a very affordable option when it comes to organization and clutter reduction. You can use different colors of heat shrink to distinguish keys or other similar objects from each other. It’s also great at tackling wire management by bundling multiple wires together and preventing them from getting tangled
- Withstands Extreme Weather Conditions: Heat shrink is designed with durability in mind. It is resistant to tears and punctures and will not become weak or brittle when exposed to the elements/extreme temperatures
- Adaptable to Fit Any Dimensions Required: Heat shrink is available in a wide range of sizes and even shapes, such as end caps, right angle boots, and breakout boots just to name a few. It can even be designed to meet custom size requirements. These convenient options make it possible to take on any size project with confidence
Overall, although most people don’t think about heat shrink until they need it, it’s a top go-to when it comes to work and home projects. It only requires the right heat shrink application material and a heat source, and you are on your way to a watertight seal!
