Is A Square Carpet Better With A PVC Base Or Environmentally Friendly Asphalt?

PVC square carpets and environmentally friendly asphalt square carpets are two commonly seen office carpets on the market. What are the advantages and disadvantages of the two types of square carpets? We start from the source.

1.The source of PVC

The chemical name of PVC is polyvinyl chloride, which is a non-toxic and odorless white powder. It has high chemical stability and good plasticity. Except for a few organic solvents, it can withstand any concentration of hydrochloric acid, less than 90% sulfuric acid, 50-60% nitric acid, and less than 20% caustic soda at room temperature, and is also quite stable for salts; PVC has poor thermal stability and light resistance. It can start to decompose and release hydrogen chloride (HCl) gas above 140 ℃, causing PVC to change color. PVC has excellent electrical insulation properties and generally does not burn. It can burn on flames and release HCl, but it extinguishes itself when it leaves the flame. It is a "self extinguishing" and "difficult to ignite" substance.

2.Sources of environmentally friendly asphalt

Asphalt is a product of the crude oil processing process, which is a viscous liquid, semi-solid or solid with black or black brown color at room temperature. It mainly contains hydrocarbons and non hydrocarbon derivatives soluble in trichloroethylene, and its properties and composition vary with the source of crude oil and production methods. 90% of carpets in Europe are made of environmentally friendly asphalt due to the recyclability of asphalt. Over 90% of square carpets used in Europe are environmentally friendly asphalt products. This is also a detail that Europe attaches great importance to environmental protection. Due to the recyclability and wide availability of environmentally friendly asphalt, the price is slightly cheaper compared to PVC square carpets.

Most Asians choose PVC square carpets. Especially in Japan, the annual consumption of carpets is astonishing, reaching 30 million square meters. Due to its affordable price and the unique cleanliness of the Japanese nation (mainly used in tatami mats and indoor spaces), carpet replacement is very frequent. The main reason for choosing PVC carpets in China is because they feel clean, hygienic, and odorless.

In short, choosing according to one's own needs is the most important thing. If one considers the feelings of others or nature in addition to making choices, it would be perfect.
