2. The Basics of Heat Shrink Technology • Heat shrink tubing is a thermoplastic cylinder constructed with cross-linking polymers that offer strain relief, moisture resistance, protection, and insulation to wires, cables, and terminals. • It was invented by a chemical engineer in the 1950s by using radiation or heat to create a tubing that would shrink when heated. • Heat shrink is available in various sizes and can be applied to various sized wires and cables. • The shrink ratio refers to the rate of shrink. For example, a 2-1 ratio means the heat shrink will shrink to one half its diameter.

3. Introduction to Double-Wall Heat Shrink • Double-wall heat shrink tubing is a multi-layer thermoplastic product with an interior adhesive lining for extra protection and insulation of the encompassed product. • The outer layer of the double-wall tubing acts as an extra layer of protection from impact, abrasion, and tears. • Dual wall heat shrink tubing works as a strain relief of wires and connections while doubling as an insulator from extreme temperatures. • This type of heat shrink tubing is available in shrink ratios ranging from 2:1 to 4:1.

4. The Science Behind Double-Wall Heat Shrink • There are several types of materials used to create a double-wall heat shrink tubing product. While basic polyvinyl chloride (PVC) is a cheaper material cost-wise, polyolefin offers superior protection and insulation without breaking the bank. • Polyolefin is a synthetic substance that can be easily manipulated without compromising the quality and durability. • It offers high resistance to liquids, moisture, chemicals, and fluctuating extreme temperatures. The material itself can withstand temperatures ranging from 125°C to 135°C.

5. The Superior Performance of Double-Wall Heat Shrink • The function of dual-wall adhesive heat shrink tubing is to provide a higher level of insulation and protection in situations where the components are exposed to harsh environmental conditions. • The composition of the double-wall tubing offers resistance to moisture, chemicals, ultraviolet light, and corrosion. • Constructed with durable materials, the dual-wall heat shrink tubing can withstand high voltages and protect against impact, tears, and abrasions. • Having a double layer can also extend the longevity of the protected components as it provides strain relief, reducing the risk of damage from vibration, movement, and weight stress.

6. Applications of Double-Wall Heat Shrink With adhesive-lined heat shrink tubing, the application possibilities are endless. Protection and identification of wires, cables, connectors, and terminals are essential for all industries including medical, marine, and military fields. • Electrical and electronics industry: This industry is a top user of double-wall heat shrink tubing to protect and insulate wires and cables. • Automotive and aerospace industry: As dual-wall tubing shields components from exposure to harsh weather conditions and movement from vibration, this industry is a top customer of tubing manufacturers. • Telecommunications and data communication industry: With the advancement of modern technology, this industry sees new developments on a daily basis that call for having an extra layer of protection and insulation for optical fibers, cables, and wires.

7. ShrinkShop's Double-Wall Heat Shrink Solution r Performance of Double-Wall Heat Shrink • As a prominent dual-wall heat shrink supplier, ShrinkShop uses specialized materials and polyolefin to offer superior quality for all applications. • Our tubing features durable adhesive lining, ultraviolet protection, and a resilient outer layer to protect against moisture, temperatures, corrosion, and abrasion. • By using color-coded heat shrink tubing or custom-printed heat shrink tubing, your businesses can label wiring for easy identification and include your company logo. • We can print your company logo or product information on one or both sides of the double-wall heating shrink tubing so that the text will not be distorted once the heat is applied to the tubing.
