The performance is slightly different. Plastic floor with dense bottom plastic floor is a kind of plastic floor without foam layer, which has better compressive performance and is suitable for places with high pressure. The floor with dense plastic floor has better indentation resistance than the floor with foam floor. After a heavy object is placed for a long time, it will not leave a long-term indentation, even if there is an indentation, the indentation is not obvious. Foamed plastic floor will be more comfortable and sound-absorbing when used on sidewalks! However, under the long-term pressure of heavy objects, the plastic floor with foamed base is easy to leave indentation.
