First. Material composition

1. PVC plastic floor:
- Mainly made of polyvinyl chloride (PVC) and copolymer resins. Among them, polyvinyl chloride is a synthetic resin with good flexibility and processability.
- Fillers, such as calcium carbonate, are often added to reduce costs and improve performance. The quality and proportion of the filler will affect the strength and stability of the floor.
- Also contains plasticizers to make the PVC material softer and increase the elasticity of the floor. However, some plasticizers may have environmental risks, such as phthalate plasticizers may have potential harm to human health.
- In addition, there are stabilizers, colorants and other auxiliary materials. The role of the stabilizer is to prevent the degradation of PVC during processing and use, and the colorant gives the floor a variety of colors and patterns.

2. SPC Stone Plastic floor:
- Polyvinyl chloride and stone powder as the main raw materials. Stone powder is usually calcium carbonate, quartz sand, etc., accounting for a relatively high proportion, generally up to more than 60%.
- The addition of stone powder makes the floor have higher stability and strength, but also increases the weight of the floor.
- Contains plasticizers, stabilizers, carbon black and other ingredients. The effect of plasticizer is similar to that of PVC plastic floor, but the amount is relatively small. The types and effects of stabilizers are also different, mainly to prevent polyvinyl chloride

And stone powder under high temperature and ultraviolet irradiation occurs aging and discoloration. Carbon black plays a role in UV resistance and enhances the stability of the floor color.

Second, the production process

1. PVC plastic floor:
- Coating method: The PVC paste resin is coated on the substrate, and the floor is formed by heating and curing. The floor surface produced by this process is smooth, but the thickness uniformity is poor.
- Calendering method: The PVC material is calendered into thin sheets by the calendering machine, and then combined with the base material. The floor produced by calendering method has uniform thickness and good surface quality, but the equipment investment is large.
- Extrusion method: PVC material is extruded into sheet or coil by extruder, and then subsequent processing. Extrusion method has high production efficiency and low cost, but the dimensional accuracy of the floor is relatively low.

2. SPC Stone Plastic floor:
- First, raw materials such as PVC and stone powder are mixed, and the mixture is heated and plasticized by a plasticizing extruder to extrude it into a dense sheet.
- The sheet is moulded and rolled so that it has a specific thickness and size.
- The sheet is naturally cooled after forming to ensure its stability and strength.
- The surface is then UV treated to enhance the wear resistance, stain resistance and UV resistance of the floor.
- Finally, the process of opening and backing is processed to facilitate installation and improve the moisture resistance of the floor.

Third, performance characteristics

1. Stability:
PVC plastic floor: relatively poor stability, susceptible to temperature and humidity. In high temperature environment, PVC material may soften and deform; At low temperatures, it may become hard and brittle. At the same time, changes in humidity can also cause the floor to arch,

Metamorphosis.
- SPC stone plastic floor: strong stability, little affected by temperature and humidity. Due to the addition of stone powder, the thermal expansion coefficient of SPC floor is extremely low, there will be no thermal expansion and contraction phenomenon, and it will not arch deformation due to humidity changes. This makes SPC flooring

Suitable for a variety of different climatic conditions and environments.

2. Wear resistance:
PVC plastic floor: poor wear resistance, especially in high-flow places, such as shopping malls, hospitals, etc., prone to scratches and wear.
- SPC stone plastic floor: good wear resistance, its surface UV coating and the hardness of stone powder make it able to withstand greater friction and wear. SPC flooring usually has a high wear revolution and can meet the needs of a variety of commercial and domestic places.

3. Elasticity and foot feel:
- PVC plastic floor: soft texture, good elasticity, comfortable feet. When walking or standing, it can provide a certain buffer and reduce foot fatigue.
- SPC stone plastic floor: poor elasticity, hard feet. Due to the high proportion of stone powder, SPC floors are relatively hard and lack elasticity. Standing or running for long periods of time may cause discomfort to the feet.

4. Anti-slip performance:
PVC plastic floor: has good anti-slip performance, especially in the case of special treatment of the surface. Its anti-slip coefficient is usually above 0.5, which can effectively prevent the occurrence of slip accidents.
- SPC stone plastic floor: anti-skid performance is also good, its surface texture and UV coating can provide a certain amount of friction. However, compared with PVC plastic floor, the anti-skid performance of SPC floor may be slightly inferior.

5. Waterproof performance:
PVC plastic floor: waterproof performance is good, because the PVC material itself is waterproof, coupled with the sealing splicing method, can effectively prevent water penetration.
- SPC stone plastic floor: excellent waterproof performance. The main components of SPC floor polyvinyl chloride and stone powder are not absorbent, and the floor is connected with a lock, good sealing, and can completely prevent water penetration. So, SPC floor

Suitable for humid environment, such as bathroom, kitchen, etc.

6. Sound absorption performance:
PVC plastic floor: has a certain sound absorption performance, can reduce the spread of noise. Its sound absorption coefficient is usually above 0.15, which can effectively reduce indoor noise.
- SPC Stone plastic floor: The sound absorption performance is relatively poor. Due to the high proportion of stone powder, the density of SPC floor is larger, the sound spreads faster in it, and the sound absorption effect is not as good as that of PVC plastic floor.

Fourth, environmental performance

1. PVC plastic floor:
Some chemicals may be added during the production process, such as plasticizers, stabilizers, etc., some of which may pose potential hazards to human health and the environment.
- Some low-quality PVC plastic floors may release harmful gases such as formaldehyde and benzene, affecting indoor air quality.
- However, with the improvement of environmental protection requirements, there are now many environmentally friendly PVC plastic floors, using non-toxic, odorless plasticizers and stabilizers, in line with national environmental standards.

2. SPC Stone Plastic floor:
- The main ingredients are natural stone powder and polyvinyl chloride, which has good environmental performance. Stone powder is a natural mineral, non-toxic, tasteless, will not cause harm to human health and the environment.
- PVC can also use environmentally friendly raw materials and processes in the production process to reduce harmful gas emissions.
- SPC floor usually does not contain formaldehyde, benzene and other harmful substances, in line with national environmental standards, and even can meet European environmental standards.

Fifth. Installation method

1. PVC plastic floor:
- Can be laid by adhesive or latch. Adhesive method requires the use of special glue to paste the floor on the ground, the construction is relatively complex, the need for professional personnel to operate. What's more, glue may release harmful gases to indoor air

Quality makes a difference.
- The locking method is relatively simple, the floor is connected through the locking, no glue is required, and the installation is convenient and quick. However, the quality and accuracy of the latch will affect the installation effect and stability of the floor.

2. SPC Stone Plastic floor:
- Just lay with a latch, no glue or keel required. When installing, align the latches on the floor and gently tap to complete the installation. This installation method is simple and fast, not only saves construction time and cost, but also avoids glue

Bring environmental problems.
- The locking design of SPC floor is usually more precise, which can ensure that the connection between the floor is firm and reliable, and is not easy to loosen and deformation.

Sixth. Applicable places

1. PVC plastic floor:
- Mainly applicable to schools, kindergartens, playhouses, offices and other places. These places have high performance requirements for non-slip, sound-absorbing, and beautiful floors, and PVC plastic floors can just meet these needs.
- However, due to the poor stability and wear resistance of PVC plastic flooring, it is not suitable for high temperature, high humidity, high flow places, such as kitchens, bathrooms, shopping malls, etc.

2. SPC Stone Plastic floor:
- Mainly applicable to families, hotels, restaurants, schools, hospitals and other places. These places have high requirements for the stability, wear resistance, water resistance and other properties of the floor, and SPC stone plastic floor can just meet these needs.
- SPC floor is also suitable for the floor heating system, its good thermal conductivity can ensure the rapid transfer of floor heating heat, improve the uniformity of indoor temperature.

Seventh. Price

1. PVC plastic floor:
- The price is relatively low, generally ranging from tens of yuan to more than 100 yuan per square meter. Its price mainly depends on the thickness of the floor, quality, brand and other factors.
- For consumers on a limited budget, PVC plastic flooring is a cost-effective option.

2. SPC Stone Plastic floor:
- The price is relatively high, generally ranging from more than 100 yuan to more than 200 yuan per square meter. Its price mainly depends on the thickness of the floor, quality, brand, surface treatment and other factors.
Although the price of SPC stone plastic floor is higher, its performance is superior, the service life is long, and the comprehensive cost may not be higher than that of PVC plastic floor.

In summary, there are differences between PVC plastic flooring and SPC stone plastic flooring in material composition, production process, performance characteristics, environmental performance, installation methods, applicable places and prices. Consumers should choose according to their own needs and budget

Comprehensive consideration, choose their own flooring products. For example, if the environmental performance requirements are high, you can choose SPC stone plastic floor; If the budget is limited, you can choose PVC plastic flooring. At the same time, we should also pay attention to the choice of regular brands and

Manufacturer's products to ensure the quality and performance of the floor.
