Is PVC flooring really as environmentally friendly as advertised?

Speaking of this topic, we must first explain what is pvc?

Pvc is an abbreviation of Poly Vinyl Chloride, a polymer material that uses one chlorine atom to replace one hydrogen atom in polyethylene. The structure of this material is as follows: [?CH2?CHCl?]n

"Pvc flooring" refers to floors made of PVC materials. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants, and other auxiliary materials are added. On a sheet-like continuous substrate, a coating process or a calendar, extrusion, or extrusion is applied. Process production. It has many advantages such as strong decoration, easy installation, environmental regeneration, ultra-light, thin, wear-resistant, and convenient maintenance. However, people are still more concerned about whether the pvc flooring is as environmentally-friendly and safe as it is advertised.

Is pvc flooring harmful to people?

1. The pvc material is non-toxic, colorless, and odorless, but it will slowly decompose hydrogen chloride gas at high temperatures. The burning of PVC is divided into two steps. The hydrogen chloride gas and the diene containing double bonds are first burned and decomposed at 240°C-340°C, and then carbon combustion occurs at 400-470°C.

2. pvc flooring slowly decomposes hydrogen chloride gas harmful to human body in the highest continuous use temperature above 130°C. This gas is mainly produced in polyvinyl chloride and DOP (molecular formula: C24H3804, molecular weight: 390.30).

However, the average temperature of human skin and body is usually 25-35°C, and the HCL harmful gas in pvc floor is released in a continuous high temperature environment above 130°C. Pvc flooring releases HCL and other harmful gases at a specific temperature (above 130°C) and environment (boiling water above 100°C). In other environments, pvc flooring is an environmentally friendly decoration material that is very suitable for human living and activities in the interior space.
