With the rapid development of decorative materials, various materials and manufacturing processes are constantly being updated. In the fields of doors and windows, pipes, and floors, the use of PVC and uPVC Wall Panel is becoming more and more widespread.
PVC has plasticisers, whereas uPVC does not.
Introduction to PVC and uPVC
PVC, full name Polyvinyl Chloride, is a thermoplastic resin material and is a commonly used plastic material. It has excellent stability, corrosion resistance, mechanical properties, and conductivity, among others. Because of its relatively low manufacturing cost and excellent performance, it has been widely used in the construction and engineering fields. PVC materials can also be modified by additives to produce various types such as UV stabilizers, anti-aging agents, and flame retardants.
uPVC, which stands for unplasticized Polyvinyl Chloride, also known as rigid PVC. It is a high-molecular-weight material that has been further modified based on PVC material to make it more rigid and stable. uPVC roof panel exhibits better corrosion resistance and high-temperature resistance, allowing it to withstand climate changes and various external environmental challenges. uPVC is often used in combination with materials such as fiberglass and aluminum to create various products such as doors, windows, and pipes.
Differences between PVC and uPVC
(1) Density
uPVC has a higher density than PVC due to the addition of special additives during the manufacturing process. These additives also affect the material's performance under high temperatures, making uPVC more stable and durable compared to PVC.
(2) Thermal stability
In high-temperature environments, PVC tends to expand and soften, making it more prone to deep yellowing and deformation in hot climates. uPVC, on the other hand, exhibits stronger resistance to high temperatures and can maintain stability without deformation even in hot desert regions.
(3) Strength and hardness
uPVC has higher hardness than PVC. Doors, windows, and pipes made of uPVC are more rigid and stable, capable of withstanding greater pressure.
(4) Cost
The manufacturing cost of PVC materials is relatively low, making PVC products, such as flooring, more popular. uPVC, due to the addition of more special additives, has a higher cost. Consequently, uPVC products are more high-end and of better quality, such as high-end doors, sliding doors, etc.
In summary, uPVC offers higher durability and stability compared to PVC, making it more suitable for various environmental challenges such as high temperatures and climate changes. Therefore, when selecting building materials, it is necessary to choose different materials based on specific circumstances.
