SPC floor ** does not require ** to use glue, the following is a specific explanation and summary:

1. ** Material composition ** : SPC floor is a new type of stone plastic composite material, mainly using calcium powder as raw materials, through the plasticization process, by the substrate layer, transparent layer, wear-resistant layer, decorative layer and other multi-layer combination.

2. ** Production process ** : SPC floor does not need to use glue in the production process. It is usually a stable substrate layer formed by high temperature hot pressing of high-precision equipment, avoiding problems such as formaldehyde that may be caused by glue bonding.

3. ** Structural characteristics ** : The structure of SPC floor includes PUR transparent layer, pure PVC wear-resistant layer, rich color film layer, SPC polymer substrate layer, soft and quiet rebound layer, etc. These layers are closely combined through a specific process, without the use of glue.

4. ** Environmental protection ** : Because no glue is used, SPC floor will not produce harmful substances such as formaldehyde during manufacturing and use, which is an environmentally friendly and non-toxic material.

In summary, SPC flooring does not need to use glue, and its unique production process and material combination make it an environmentally friendly, non-toxic and formaldehyde-free flooring material.
