DATASHEET

 

What is 3:1 Heat Shrink Tubing?

 

 

3:1 heat shrink tubing is a type of thermoplastic tubing designed to shrink its diameter to one-third of its original size when heated. This feature makes it an excellent solution for insulating wires, offering mechanical protection, and bundling cables in various electrical and industrial applications. Non adhesive heat shrink tubing, like the 25m rolls we provide, ensures flexibility and durability without inner glue lining, ideal for situations where residue-free removal or specific environmental resistance is required.

 

 

Benefits of Non Adhesive 3:1 Heat Shrink Tubing

 

 

The non adhesive 3:1 heat shrink tubing delivers strong protection against abrasion, moisture, and environmental factors while remaining easy to remove if necessary. Its 3:1 shrink ratio allows it to fit tightly around irregular objects, providing a reliable seal and excellent strain relief for cables and connectors. The 25m rolls offer convenience for larger projects and bulk use, making it a cost-effective choice for professionals and DIY enthusiasts alike.

 

 

Applications and Usage Tips

 

 

This 3:1 heat shrink tubing is widely used in electrical wiring, automotive repairs, marine applications, and general cable management tasks. To apply, slide the tubing over the targeted area and heat with a heat gun evenly until it shrinks securely around the surface. The non adhesive nature ensures no sticky residue, making it ideal for temporary fixes or areas where future adjustments may be needed. Its versatile design supports various wire sizes due to its significant shrink ratio.

Perfect!
Size: 3 Pairs - Gray, Green, Pink
When my heel skin started cracking, I of course found the internet hacks that went along the lines of put some moisturizing something (cream, Vaseline) on your feet and put socks on and go to sleep. Somehow many issues. While putting on the socks, I already wiped off the moisturizer. It feels terrible. My sleeping self hates socks apparently! I always kick them off, the socks are covered in moisturizer, and it’s all over my blanket. Yuck! So when I found these socks I was unsure but willing to try. These are exactly what I needed! They have this gel-y coating inside that does not absorb the moisturizer, so it actually gets absorbed into your skin. They are snug without cutting off circulation, and along with kerasal, my heels are being healed! Could not recommend enough.

They keep sheets from getting greasy.
Size: 3 Pairs - Gray
These are good. I like that I can put lotion on my heels when I go to bed and not get my sheets greasy. They do a good job on that and a pretty good job keeping the moisturizer on. Since the toes are open, they aren’t hot. The gel doesn’t seem to do anything, though.
