Why can stone plastic spc floor be fireproof

With the strengthening of people’s safety awareness, people not only start to pay attention to the environmental protection of the materials, but also start to pay attention to the fire rating of the materials in the selection of decoration materials. In recent years, with the rapid development of China’s economy, there have been more and more use of dangerous goods that are likely to cause fires in production and life, and the risk of fires has also increased correspondingly. The number of fires and the resulting property losses and personnel The number of casualties is on the rise. Therefore, it is necessary to choose decoration materials with a high fire rating.

The fireproof index of qualified spc floor can reach level B1, which is the highest standard for floor fire protection, second only to stone. The spc floor itself will not burn and can prevent burning; the smoke produced by the high-quality spc floor when passively ignited will never cause harm to the human body, and will not produce suffocating toxic and harmful gases. (According to the figures provided by the security department: 95% of the people injured in the fire are caused by the toxic smoke and gas produced during the fire).

Since the main raw material of spc floor is polyvinyl chloride, the full English name is poly vinyl chloride, or pvc for short. The softening or melting temperature range of pvc: 75~90°C, the upper part of the burning flame is yellow and the lower part is green and there is smoke, and it will be automatically extinguished away from the fire. It can be used as an identification method for spc floor.
