PVC Foam Board Recognition Three Major Misunderstandings
- Nov 14, 2018 -

1、Flame retardant is not "burning"

Some people want to use a lighter to burn PVC foam board, to see if it can be burned up, it is not fireproof when burned, it is flame retardant. This is a common misunderstanding. The national requirements for the fire-retardant grade of PVC foam board are up to BF1-T0. According to the national standard, non-combustible materials are classified as fire-proof grade A, such as stone, brick, etc. Bf1-T0 flame retardant standard The technology contains cotton balls with a diameter of 10mm. The alcohol is placed on the PVC floor and burned naturally. After the cotton balls are burned out, the diameter of the burnt PVC floor marks is measured. If it is less than 50mm, it is BF1-T0. Flame retardant standard.


2、Not environmental protection is not based on "nose smell"

PVC material itself is formaldehyde-free. PVC flooring is also not allowed to use formaldehyde in the production process. Some advanced PVC foam boards will use new calcium carbonate raw materials, and the freshly produced products will have a faint taste. It can cause harm to people's bodies and it will not make people feel uncomfortable. After being placed in the ventilation for a while, it will dissipate.


3、"Abrasion resistance" is not "do not scratch with a sharp weapon"

When some people ask about the service life and wear resistance of PVC foam board, they can take out sharp tools such as knives or keys and cut them on the surface of PVC floor. If they are scratched, they are not wearable. In fact, the national abrasion resistance test for PVC flooring is not simply a sharp surface on the surface, but is determined by the national inspection agency.
