What difference between Customized Extrusion Line of PVC UH Pipe and Customized Extrusion Line of UPVCUH Pipe

The difference between a Customized Extrusion Line of PVC-UH Pipe and a Customized Extrusion Line of UPVC-UH Pipe primarily relates to the material composition of the pipes they are designed to produce:

1. Material Difference

PVC-UH (Polyvinyl Chloride - Unplasticized, High Strength): This material refers to unplasticized PVC with enhanced mechanical properties, especially in terms of higher strength, pressure resistance, and durability. It is used for heavy-duty applications, such as pressure piping for water or industrial fluids.

UPVC-UH (Unplasticized Polyvinyl Chloride - Ultra High): UPVC is simply unplasticized PVC (rigid PVC), but "UH" (Ultra High) signifies a particular grade with superior mechanical properties, just like PVC-UH. The terms PVC-UH and UPVC-UH are sometimes used interchangeably, but UPVC tends to emphasize that the PVC is rigid and has not been softened with plasticizers.

2. Terminology

PVC-UH and UPVC-UH may technically refer to the same material. However, the industry uses different terms in various regions:

In European markets or industries, UPVC is the commonly accepted term for rigid, unplasticized PVC.

In other regions or specific industries, PVC-U or PVC-UH may be used.

3. Extrusion Line Differences

Customized Extrusion Line for PVC-UH Pipe: This line is designed for producing high-strength PVC-UH pipes, which require more precise control over processing parameters to maintain the enhanced mechanical properties of the material.

Customized Extrusion Line for UPVC-UH Pipe: Similarly, this line is geared towards producing UPVC-UH pipes but may focus more on regions or markets where the term UPVC is used. The equipment would still be designed to handle the rigid and high-performance characteristics of the material.

4. Applications and Specifications

PVC-UH Pipes: Typically used for pressure applications, water supply, sewage systems, and industrial piping systems where high mechanical strength and resistance to corrosion are crucial.

UPVC-UH Pipes: Similar applications but may also include additional markets or industries that specify the use of UPVC by name.

In summary, the difference is mainly terminological, with PVC-UH and UPVC-UH referring to the same type of high-strength, unplasticized PVC, and the extrusion lines being designed specifically to meet the processing needs of these materials. The choice of term often depends on regional preferences or specific industry standards.
