Polyolefin vs PVC Heat Shrink Tubing – Which is Best?

When deciding between Polyolefin heat shrink and PVC heat shrink  (polyvinyl chloride) for a project, there are several factors to consider, such as the application, the environment in which the material will be used, and the desired properties of the finished product. 

Polyolefin Heat Shrink 

Polyolefin heat shrink is a type of plastic that is made from a polymer of ethylene and propylene. It also has a wide operating temperature range and is resistant to chemicals, oils, and fuels. These properties make polyolefin heat shrink a good choice for applications that require insulation and environmental resistance, such as electrical wiring and cable bundling.

PVC Heat Shrink Tubing

On the other hand, PVC heat shrink Tubing is made from polyvinyl chloride, which is a widely used plastic material. PVC heat shrink tubing is known for its flexibility and ease of use. This makes it a good choice for applications that require flexibility and ease of installation, such as labeling and identification. 

It also has a good resistance to abrasion, chemicals, and extreme temperature changes.

When choosing between polyolefin heat shrink and PVC heat shrink, it’s important to carefully evaluate the specific requirements of the project and the environment in which the material will be used. 

For example, if the project involves insulation, chemical resistance, and a wide operating temperature range, polyolefin heat shrink may be a better choice. If the project involves flexibility, ease of use, and abrasion resistance, PVC heat shrink may be a better choice. 

PVC is a type of plastic that shrinks at a lower temperature than Polyolefin. Because PVC requires less heat to shrink compared to Polyolefin tubing, it is more suitable for heat-sensitive projects.


Clear vs Glossy PVC 

Manufacturers can create PVC in various forms, such as clear and glossy.


Clear PVC 

Clear PVC offers improved visibility due to its transparency. This makes it the ideal material for applications where it is necessary to view the contents under a jacket or other item. 


Glossy PVC 

Glossy PVC has a shiny surface that gives it a sleek, polished appearance. In situations where visual presentation is important and people want a shiny finish, glossy PVC can enhance the overall look of a product.
