Heat shrink sleeving is a versatile and essential component used in various electrical and mechanical applications. And among the many types available, LSZH (Low Smoke Zero Halogen) heat shrink sleeving has gained popularity due to its unique properties.
Thus, in this blog, we’ll compare LSZH heat shrink sleeving with other common types of sleeving, examining their benefits, applications, and differences. By the end, you’ll have a clear understanding of which type of sleeving might be the best fit for your needs.
So, let’s have a look.
What is LSZH Heat Shrink Sleeving?
LSZH heat shrink sleeving is a type of protective tubing used to insulate wires and cables. What sets LSZH apart is its composition. Unlike traditional materials, LSZH sleeving is made from materials that emit minimal smoke and no halogen when exposed to fire.
This makes it an excellent choice for environments where safety is a top priority, such as public buildings, transportation systems, and confined spaces.
The Benefits of LSZH Heat Shrink Sleeving
● Safety
The primary advantage of LSZH heat shrink sleeving is its safety. In the event of a fire, LSZH materials produce very little smoke and do not release toxic halogen gases like chlorine or bromine. This significantly reduces the risk of inhalation injuries and improves visibility, aiding in safe evacuations.
● Environmental Impact
LSZH materials are also more environmentally friendly compared to traditional halogenated materials. They do not release harmful gases that can contribute to acid rain and other environmental issues. This makes LSZH a greener option for various applications.
● Compliance with Regulations
In many industries, especially those involving public safety, regulations require the use of low smoke and halogen-free materials. LSZH heat shrink sleeving complies with these stringent standards, making it a go-to choice for compliance-sensitive projects.
Other Types of Heat Shrink Sleeving
● Polyolefin Heat Shrink Sleeving
Polyolefin is the most common material used for heat shrink sleeving. It is highly flexible, flame-retardant, and offers excellent insulation properties. Polyolefin sleeving is widely used in automotive, electrical, and electronic applications due to its versatility and cost-effectiveness.
Some of the advantages of polyolefin heat shrink sleeving are highlighted below.
- Versatile and flexible
- Flame-retardant
- Good electrical insulation
- Cost-effective
Moving on, let’s look at some of the disadvantages of polyolefin heat shrink sleeving.
- Releases toxic fumes when burned
- Higher smoke production compared to LSZH
● PVC Heat Shrink Sleeving
PVC (Polyvinyl Chloride) heat shrink sleeving is another widely used type. It is known for its durability and resistance to chemicals, making it suitable for industrial applications. However, PVC is not as environmentally friendly as LSZH or polyolefin.

Some of the advantages of PVC heat shrink sleeving are given below.
- Durable and chemical-resistant
- Cost-effective
- Available in various colours
Moving on, let’s look at some of the disadvantages of PVC heat shrink sleeving.
- Releases harmful chlorine gas when burned
- Higher smoke production compared to LSZH
- Less flexible than polyolefin
● Silicone Heat Shrink Sleeving
Silicone heat shrink sleeving is prized for its high-temperature resistance and flexibility. It is often used in aerospace, automotive, and industrial applications where extreme temperatures are common.
Some of the advantages of silicone heat shrink sleeving are highlighted below.
- Excellent high-temperature resistance
- Highly flexible
- Good electrical insulation
However, silicone heat shrink sleeving can have certain disadvantages as highlighted below.
- Expensive
- Not as widely available as polyolefin or PVC
- Can be overkill for standard applications
Comparing LSZH with Other Types of Sleeving
● Safety and Environmental Impact
When it comes to safety and environmental impact, LSZH heat shrink sleeving stands out. Unlike polyolefin and PVC, LSZH does not emit harmful halogen gases when burned, reducing health risks and environmental damage.
This makes LSZH the preferred choice for applications in confined spaces, public buildings, and transportation systems where fire safety is crucial.
● Flexibility and Versatility
Polyolefin and silicone sleeving are known for their flexibility and versatility. Polyolefin is cost-effective and widely used in many applications, while silicone offers superior high-temperature resistance. LSZH, although flexible, may not match the extreme flexibility of silicone.
However, it strikes a good balance, offering sufficient flexibility for most applications while providing added safety benefits.
● Cost Considerations
Cost is an important factor in selecting heat shrink sleeving. Polyolefin and PVC are generally more affordable compared to LSZH and silicone. LSZH tends to be more expensive due to its specialised composition and safety features.
Silicone, being the most specialised, is often the costliest. For budget-conscious projects, polyolefin and PVC may be more attractive, but the long-term safety and compliance benefits of LSZH can justify the higher initial investment.
● Application Specificity
The choice of heat shrink sleeving often depends on the specific application requirements. For general-purpose applications, polyolefin is a reliable and cost-effective choice.
In environments where chemical resistance is needed, PVC might be suitable. For high-temperature applications, silicone is the best bet. However, for projects where fire safety, low smoke production, and environmental impact are critical, LSZH is the ideal choice.
Conclusion
Thus, LSZH heat shrink sleeving offers significant advantages in terms of safety and environmental impact. This makes it a preferred choice for applications where these factors are paramount.
And while other types of sleeving like polyolefin, PVC, and silicone each have their own strengths, LSZH provides a balanced solution for many modern applications. Thus, when selecting the right heat shrink sleeving, consider the specific needs of your project, including safety, flexibility, cost, and environmental impact.
By doing so, you can ensure that you choose the best material for your needs, which will ultimately enhance the performance and safety of your electrical and mechanical systems.
