The American CBS TV news ace program “60 Minutes” exposed that the composite floor formaldehyde produced by XXX Company, the largest floor company in the United States, in Jiangsu seriously exceeded the standard. According to the survey, all the laminate flooring produced by LL in China exceeds the formaldehyde standard of California by 6-7 times. The poisonous flooring incident in the United States has further affected the sales of laminate flooring made by Chinese factories in foreign countries.
After the harmful floor incident, this really zero formaldehyde emission SPC floor appeared.
Chinese companies must also actively reverse the situation. SPC stone-plastic flooring suddenly corners and overtakes, becoming popular in Europe, America, Southeast Asia, Japan and South Korea.
Chinese companies began to do SPC research and development around 2013. In a short period of time, SPC stone plastic flooring (called RVP flooring in some countries) in Europe, America, Japan, South Korea and other countries has been taken over by Chinese factories for more than half.
However, in recent years, we have been doing export, which is very recognized by foreign markets. However, there is generally a complex of “natural materials” in China, and solid wood and solid wood composite/reinforcement are more recognized, and the development process of the domestic market is slow.
With the development of the times, the high-quality SPC floors we produced have also begun to slowly return to China.

What is SPC floor?
After the poisonous floor incident, this really zero formaldehyde emission SPC floor appeared
Calcium carbonate may be understood by most people, but it is actually the component of stone, while PVC is actually polyvinyl chloride.
It is a kind of light yellow powder and polymer compound. It is one of the largest plastic products in the world. It is cheap and widely used. PVC can be divided into soft PVC and hard PVC. Soft PVC is generally used for floors, ceilings and leather. Surface layer; and hard PVC does not contain softener, so it has good flexibility, easy to shape, not easy to be brittle, non-toxic, non-polluting, long storage time, so it has great development and application value. Polyvinyl chloride is an environmentally friendly and non-toxic renewable resource. It has been widely used in people’s daily life, such as pipes, plates, blood transfusion equipment and so on. The other structures are synthesized with calcium carbonate and PVC at high temperature and high pressure, so these layers can be “similarly compatible” in the process to finally synthesize the SPC floor.
①UV layer: located on the wear-resistant layer, after surface coating, UV wear-resistant treatment (matt, semi-matt, bright). Increase the wear resistance of the product. The UV wear-resistant layer has very good stain resistance and will not be scratched in daily use. Just like the tile floor, you only need a broom or mop to clean when there is dirt. There are taboos in the use of any floor. Just like when we use ceramic tiles and marble floors, we must avoid hammers and other hard objects. When using wooden floors, we must avoid the contact of cigarette butts and other light and dark fires; in the process of using SPC floors It is necessary to avoid the deliberate depiction of the knife.
②Transparent wear-resistant layer: transparent PVC is the main material. Enhanced wear resistance, easier to maintain, no sanding, no waxing; the thickness of the wear-resistant layer directly affects the service life of the floor.
③Printing layer: The texture is richer, with wood grain, stone grain, carpet grain, etc., the design is more extensive and easy to realize. The flower film of SPC floor adopts high-definition printing technology, whether it is imitation wood grain, stone grain or carpet grain, it can achieve high color fidelity and delicate patterns. The size of the lock floor is also very close to the commonly accepted wooden floor, ceramic tile, and marble floor. After the surface of the floor is embossed, the overall workmanship effect will become more high-end. From the paving effect, it is difficult for non-professionals to identify whether it is an SPC lock floor. It can fully show the warmth and softness of wooden floors; the cleanliness and quality of tiled floors; and the atmosphere and luxury of marble floors!
According to customer positioning and usage requirements, the thickness of the wear-resistant layer is 0.2~0.7mm, and the substrate layer is 3.2~8mm. The thicker the thickness of the wear-resistant layer, the wider the application range of the SPC floor, and the wear-resistant layer above 0.5mm can be applied to large places. To
SPC (Stone plactic composite) is a new type of environmentally friendly floor developed based on high technology. It has the characteristics of nearly zero formaldehyde, mildew proof, moisture proof, fire proof, insect proof, and simple installation. SPC floor is a product that extrudes PVC substrate by extruder combined with T-die, and uses three-roll or four-roll calender to separate PVC wear-resistant layer, PVC color film and PVC substrate, one-time heating lamination and embossing product , The process is simple, the fit is completed by heat, and no glue is needed. SPC floor materials use environmentally friendly formulas, do not contain harmful substances such as heavy metals, phthalates, methanol, etc., and comply with EN14372, EN649-2011, IEC62321, and GB4085-83 standards. It is very popular in developed countries in Europe and America and the Asia-Pacific market. With its excellent stability and durability, stone plastic flooring not only solves the problem of damp, mold, and rotten solid wood flooring, but also solves the formaldehyde problem of other decoration materials. It has a wide range of colors and patterns to choose from, suitable for indoor home improvement, hotels, hospitals, shopping malls and other public places.

SPC floor shrinkage rate: ≤1‰ (after tempering treatment), ≤2.5‰ (before tempering treatment), (shrinkage rate test standard: 80℃, 6 hours standard);
SPC floor density: 1.9~2.1 tons/m3; (WPC floor: 0.8~1.2 T/m³)
Advantages of SPC floor: The physical indicators of SPC floor are stable and reliable, and the chemical indicators meet international and national standards.
1. The thermal shrinkage rate and thermal warpage are small;
2. Few production processes;
3. The floor price per square meter is cheap;
4. Does not contain formaldehyde and plasticizers.
Disadvantages of SPC floor:
1. The SPC floor has high density, heavy weight and high transportation cost;
2. The SPC floor feels hard on the feet (needs to help improve the foot feel, paste foam cushion to cushion.)
How to choose SPC? Next, I will give everyone a key point~
First of all, a good floor is definitely not a recycled floor. If the price is very low, pay attention. The price of recycled products is very cheap, and the price of the same thickness varies greatly. We can also look at the side, especially the lock surface, the qualified product is smooth and delicate, not easy to break.
Secondly, looking at the shrinkage ratio, the stability of the return material is poor, and the shrinkage ratio is relatively large.

Then we can also judge by smelling that qualified products are free of any peculiar smell. If the bottom pad is made of EVA, it still smells a little bit.
Finally, we can also look at the report, because the raw materials of recycled products cannot be controlled, heavy metals and other harmful substances tend to exceed the standard.
