There are three misunderstandings in the common understanding of PVC foam board crusting board.
1. Environmental protection is not environmental protection and does not rely on "nose smell";
PVC material itself is formaldehyde-free, PVC flooring is not allowed to use formaldehyde in the production process, some high-grade PVC foam board will use new calcium carbonate raw materials, just made of products will have a faint taste, will not cause harm to people's bodies, will not make people feel uncomfortable. It will dissipate after leaving it for ventilation for a while.
2. Flame retardant is not "unburnable";
Some people want to take a lighter to burn the PVC foam board to see if it can be burned, and if it burns, it is not fireproof, and if it can't be burned, it is flame retardant. This is a common misunderstanding, the national requirements for the fire rating of PVC foam board to meet the standard of BF1-T0 level, according to the national standard non-combustible materials are set as fire class A, such as stone, face bricks, etc. The technical content of the BF1-T0 flame retardant standard is a cotton ball with a diameter of 10, dipped in alcohol, placed on the PVC floor for natural burning, after the cotton ball is burned out, the diameter of the burned PVC floor traces is measured, if it is less than 50, it is the BF1-T0 flame retardant standard.
3. "Wear-resistant, high hardness" is not "no scratches with sharp weapons";
When some people ask about the service life and wear resistance of PVC foam board, they take out a knife or key and other sharp tools, and scratch the surface of PVC flooring. In fact, the national abrasion resistance test of PVC flooring is not simply scratched on the surface with sharp weapons, but specially determined by the national testing agency.
