Black heat shrink tube 30mm price per metre
This black 30mm heat shrink tube is an essential accessory for electronics and soldering projects. It is used to insulate, protect and reinforce cables and electrical connections, ensuring durability and safety in installations.
- Material: Heat-resistant thermoplastic.
- Diameter: 30mm before shrinking.
- Colour: Black, ideal for professional and home applications.
- Presentation: Sold by the metre, allowing you to buy the exact amount you need.
This tube is compatible with a wide variety of cables and electronic connections, and is widely used in soldering stations, electronic repairs and DIY projects. Its heat shrink capability means that, when heat is applied, the tube contracts to fit tightly around the cable or component, offering optimum protection against moisture, dust and mechanical wear.
Typical uses:
- Insulating electrical and electronic cables.
- Protecting soldered connections to prevent short circuits.
- Reinforcing cables in electronic and electrical installations.
- Organising and bundling cables for a professional finish.
This product is ideal for technicians, electronics hobbyists and professionals looking for a reliable and economical product for soldering and repair work.
For best results, apply heat evenly with a hot air gun or similar, ensuring the tube shrinks correctly and fits snugly.
- Black heat shrink tube with 30mm diameter
- Sold by the metre for greater flexibility
- Ideal for cable insulation and protection
- Heat-resistant thermoplastic material
- Suitable for multiple electronic and electrical applications
Customer Questions & Answers
What are the main uses recommended for the 30 mm heat shrink tubing, and what advantages does it offer over other insulation solutions?
The 30 mm heat shrink tubing is ideal for insulating, protecting and bundling cables, especially in medium-to-large diameter electrical connections. It provides a neat, abrasion-resistant solution and is easier to apply than insulating tape, ensuring a more uniform seal when heated properly.
What is the shrink range of the tubing, and what are its dimensions and physical characteristics before and after heat is applied?
The tube has an initial diameter of 30 mm and typically a 2:1 shrink ratio, reducing to approx. 15 mm internal diameter after heat application. The wall thickness usually increases slightly after shrinking, offering greater mechanical resistance; the length may reduce by up to 10%.
What material is the heat shrink tubing made from, and what is its operating and shrink temperature range?
This type of tubing is usually made from polyolefin, a flexible material resistant to chemicals. It operates correctly between -55°C and +125°C and its typical shrink range is between 90°C and 120°C, depending on thickness and the specific brand.
What are the installation recommendations and what tools are needed to achieve an even seal?
It is recommended to cut the tubing to the desired length and place it over the cable/object before heating. For an even shrink without burning, the best option is to use a hot air gun (700–900 W, at around 200–300°C), moving it regularly. Avoid open flames so as not to damage the material.
Does the tubing comply with any electrical safety or flammability standard, and what limitations should be considered in certified installations?
Most polyolefin tubes comply with standards such as UL224 (VW-1 flammability) and RoHS directives, but it is recommended to check specific certifications with the supplier. It is not suitable for applications requiring high-voltage insulation (>1 kV) or continuous exposure to temperatures above its operating limit.
What is the black 30mm heat shrink tube used for?
It is used to insulate, protect and reinforce electrical and electronic cables and connections by shrinking when heat is applied.
How do you use this heat shrink tube?
Place it over the cable or connection and apply heat with a hot air gun so it shrinks and fits tightly.
Is it sold by the metre or in rolls?
This product is sold by the metre, allowing you to buy the exact amount needed.
Is it heat resistant?
Yes, it is made from heat-resistant thermoplastic material suitable for electronics and soldering applications.
