There are several types of PVC flooring, including homogeneous vinyl sheet and heterogeneous vinyl flooring. So what is the difference between them? They are both referred to as PVC flooring or plastic flooring. Their main raw material is PVC. although both are PVC flooring, they are very different. Let's look at the details.
Homogeneous vinyl sheet: Homogeneous is a material that is of the same quality from the surface to the entire thickness of the floor (from the surface to the bottom).
Heterogeneous vinyl flooring is made in multiple layers by a special process, usually five layers from top to bottom. They are the UV coating, the wear layer, the printing layer, the glass fiber layer and the foam backing layer. Its wear resistance is mainly reflected in the wear layer.
Therefore, structurally, homogeneous flooring is a single-layer structure. The heterogeneous flooring is a multi-layer structure.
Homogeneous vinyl sheet is made of PVC particles of various colors by a special process. It has a relatively homogeneous pattern. There are only two patterns: a non-directional floral pattern and a directional pattern.
Since the heterogeneous vinyl sheet is a layered structure, the printing layer determines the color. The printing layer can change the color and pattern at will. That is why it is available in a variety of colors: wood grain, stone grain, carpet grain, and various patterns. In other words, heterogeneous flooring has more color design options, while homogeneous vinyl flooring is relatively single.
The designs and colors are different. So the technology is very different. Homogeneous vinyl sheet products are the high-end products in PVC flooring. As the color pattern on the whole floor is 2mm thick, the mechanism of pattern formation is difficult and the production process is quite complicated. The whole production process must strictly control the uniformity of color and color difference. It is not an easy task.
And the color of heterogeneous sheets is a very simple principle of printing layers. Generally speaking, the cost of homogeneous line is five times more than that of heterogeneous line.
① PUR protective special maintenance treatment
② Compacted homogeneous floor covering
Homogeneous flooring has a higher content of stone powder. So the fire resistance is better than heterogeneous flooring, and the indentation resistance is also better.
Since homogeneous flooring is a single layer structure, its color runs through the whole thickness. This feature gives it a renovation function. Slight scratches can be ground off with a grinder, polished and repaired, and re-waxed as new for a longer service life. But not for heterogeneous flooring.
Because heterogeneous vinyl flooring contains a foam layer, it absorbs sound much better than homogeneous flooring.
Homogeneous vinyl sheet is mostly used in industrial places with high traffic due to its better wear resistance and fire resistance. For example, hospitals, educational institutions, healthcare systems, etc.
And heterogeneous vinyl flooring is mainly used for home decoration due to its rich color selection.
