As a supplier of Blue PE Laminated Viscose, I've had numerous inquiries comparing it with PVC in terms of performance. This blog post aims to provide an in - depth analysis of how these two materials stack up against each other.
Physical Properties
Strength and Durability
Blue PE Laminated Viscose combines the softness of viscose with the strength of polyethylene (PE) lamination. The viscose base offers a natural, breathable feel, while the PE layer adds a protective shield. This combination results in a material that can withstand moderate wear and tear. For instance, in applications where the material needs to be folded or handled frequently, the Blue PE Laminated Viscose retains its integrity well.
On the other hand, PVC is known for its high strength and durability. It can endure more rigorous physical stress, such as heavy impacts and abrasions. In industrial settings where a tough, long - lasting material is required, PVC often has the upper hand. However, its rigid nature can sometimes be a drawback, as it may not be as flexible as Blue PE Laminated Viscose.
Flexibility
Blue PE Laminated Viscose is highly flexible. The viscose component gives it a natural drape, making it suitable for applications where conformability is essential. It can be easily shaped and bent without cracking or losing its form. This flexibility makes it a popular choice for products like medical gowns and soft packaging.
PVC, although it can be made flexible to some extent with the addition of plasticizers, generally has a more limited range of flexibility compared to Blue PE Laminated Viscose. Over time, PVC may become brittle, especially in colder temperatures, which can affect its performance in applications that require long - term flexibility.
Chemical Resistance
Resistance to Liquids
Blue PE Laminated Viscose has some level of liquid resistance due to the PE lamination. The PE layer acts as a barrier, preventing water and other liquids from penetrating the viscose base. However, it may not be completely impervious to all types of liquids, especially strong solvents. In applications where only mild liquid exposure is expected, such as in food packaging or light - duty medical use, it performs adequately.
PVC, on the other hand, offers excellent chemical resistance to a wide range of liquids, including many solvents, acids, and alkalis. This makes it a preferred choice in chemical processing plants, laboratories, and other environments where exposure to harsh chemicals is common.
Resistance to UV Radiation
Blue PE Laminated Viscose has limited resistance to UV radiation. Prolonged exposure to sunlight can cause the viscose to degrade and the PE layer to become discolored and brittle. Therefore, it is not suitable for outdoor applications where long - term UV exposure is expected.
PVC can be formulated to have good UV resistance. By adding stabilizers and other additives, it can withstand extended periods of sunlight without significant degradation. This makes PVC a better option for outdoor products like signage, awnings, and outdoor furniture covers.
Environmental Impact
Biodegradability
Blue PE Laminated Viscose has some environmental advantages in terms of biodegradability. Viscose is a natural fiber derived from wood pulp, which is biodegradable. Although the PE lamination is not biodegradable, the overall material can break down to some extent over time. This makes it a more eco - friendly option compared to PVC in applications where disposal is a concern.
PVC is a synthetic polymer that is not biodegradable. It can persist in the environment for a long time, contributing to pollution. Additionally, the production of PVC involves the use of toxic chemicals, such as chlorine, which can have negative environmental impacts.
Recycling
Blue PE Laminated Viscose can be more challenging to recycle due to the combination of different materials. However, with the development of advanced recycling technologies, it is becoming possible to separate and recycle the viscose and PE components.
PVC recycling is also complex, as different types of PVC may require different recycling processes. Moreover, the presence of additives in PVC can make the recycling process more difficult. In general, the recycling rates of both materials are still relatively low, but Blue PE Laminated Viscose may have more potential for future - friendly recycling solutions due to the natural nature of viscose.
Cost - effectiveness
Production Costs
The production cost of Blue PE Laminated Viscose is relatively moderate. The raw materials, viscose and PE, are widely available, and the lamination process is not overly complex. This makes it a cost - effective option for many applications, especially when compared to some high - end specialty materials.
PVC production can be more expensive, especially when considering the costs associated with the use of toxic chemicals and the need for strict environmental controls during manufacturing. However, in large - scale production, the economies of scale can sometimes reduce the per - unit cost of PVC.
Lifecycle Costs
When considering the lifecycle costs, Blue PE Laminated Viscose may be more cost - effective in applications where its performance meets the requirements. Its flexibility and relative ease of use can reduce labor costs during manufacturing and assembly. Additionally, its potential for biodegradability can reduce disposal costs in the long run.
PVC, due to its high strength and durability, may have lower replacement costs in applications where a long - lasting material is required. However, the environmental costs associated with its production and disposal need to be factored in when evaluating its lifecycle costs.
Applications
Blue PE Laminated Viscose Applications
Blue PE Laminated Viscose is commonly used in the medical industry for products such as surgical gowns, drapes, and wound dressings. Its softness, breathability, and moderate liquid resistance make it suitable for these applications. It is also used in the packaging industry for products like food wraps and soft packaging due to its flexibility and ability to conform to different shapes.

PVC Applications
PVC is widely used in the construction industry for pipes, window frames, and flooring due to its strength, durability, and chemical resistance. It is also used in the automotive industry for interior components, wiring insulation, and exterior trim. In the industrial sector, PVC is used for chemical storage tanks and conveyor belts.

Conclusion
In conclusion, Blue PE Laminated Viscose and PVC have their own unique performance characteristics. Blue PE Laminated Viscose offers flexibility, breathability, and some level of environmental friendliness, making it suitable for applications where comfort and eco - friendliness are important. PVC, on the other hand, is known for its high strength, durability, and chemical resistance, making it a better choice for more demanding industrial and outdoor applications.
