1, what are the advantages and disadvantages of foamed bottom and dense bottom?

(1) Composite PVC floor with foamed bottom has two advantages: stronger sound absorption and more comfortable foot feeling because of the special honeycomb structure of foamed layer. This is because foaming agent is added to the foaming layer in the production process of PVC floor. However, it is precisely because of the addition of foaming agent that the mechanical properties and mechanical properties of the material itself decrease. Foaming agent will destroy the stable network structure of polymer to a certain extent, which is also the reason for the poor bearing capacity of foamed PVC floor, such as leaving obvious dents after pushing the cart or tables and chairs. In terms of performance, foamed PVC floor is more suitable for kindergartens, fitness centers, early education centers and other places.

(2) PVC floor with dense bottom has good compressive performance, which is the choice of factories and hospitals (except for special wards that need electrostatic conduction function).
