Comparison of WPC and SPC for Wood-Plastic Floor and Stone-Plastic Floor

WPC combines the waterproof and stability of LVT. It is also easy to install as a reinforced floor. With the increase of cork and EVA pad, the feet feel and sound insulation effect are better than that of the lock floor of LVT. 
WPC is more environmentally friendly than reinforced flooring. 
In short: WPC has both advantages over LVT and Laminate. 
1. Composition of WPC: Wood Plastic Composition = LVT Layer + WPC Core 
1. The LVT and WPC layers of WPC are bonded by glue, and the peeling strength is good, even better than that of LVT's color film and grinding tablets after hot pressing. 
2. The stability of WPC is better than that of PVC. 
WPC floor in 80 degrees plus or minus 2 degrees of high temperature for 6 hours, take out and put in 23 degrees plus or minus 2 degrees of normal temperature, 50% humidity 24 hours to observe. The following conclusions are drawn: 
The shrinkage of length is 0.11%. 
The shrinkage of width is 0.07%. 
Warpage: 0.25mm 
LVT:0.08-0.15% 
Warpage: 0.5-1.2mm
