PVC plastic flooring is a floor covering material mainly made from polyvinyl chloride (PVC) resin, along with appropriate amounts of fillers, plasticizers, stabilizers, colorants, and other additives, processed through mixing, calendering, or extrusion. It can be classified in various ways: by structure, it can be divided into homogeneous and composite flooring. Homogeneous flooring has the same material from surface to core, with color and texture running through the entire thickness, offering good wear resistance and stain resistance. It is often used in high-traffic public areas such as shopping malls and hospital corridors. Composite flooring consists of multiple layers, generally including a wear layer, a printed layer, a base layer, and a backing layer, each layer serving a different function. Different combinations meet diverse needs, and it is widely used in home decoration and commercial spaces. By form, it can be divided into roll flooring and sheet flooring. Roll flooring is usually supplied in rolls, generally 1-2 meters wide and of considerable length. Installation involves splicing or welding to create a seamless floor effect, offering good waterproofness and integrity, suitable for large-area spaces such as large supermarkets and office buildings. Sheet flooring exists in sheet form, with various specifications, making it easy to cut and splice, allowing for the creation of rich patterns and shapes. It is often used in smaller areas in home renovations, such as kitchens and bathrooms.

The upstream of the PVC plastic flooring industry chain mainly includes PVC resin, plasticizer, filler, stabilizer, and pigment raw material manufacturers. PVC resin is the core raw material. Its production processes mainly include the ethylene method and the calcium carbide method. In China, due to abundant coal resources, the calcium carbide method accounts for a larger proportion, but the ethylene method produces relatively higher quality products. Plasticizers provide the flooring with flexibility; commonly used ones include phthalates. Fillers such as calcium carbonate reduce costs and increase hardness. Stabilizers ensure product stability during processing and use. Pigments determine the color and appearance of the flooring. The midstream consists of PVC plastic flooring manufacturing enterprises. According to different processes and product types, they use calendering and extrusion methods to produce roll and sheet flooring. Through product research and development, production management, and quality control, they transform raw materials into various finished products for the market. Downstream applications are extensive, covering residential decoration, commercial buildings (shopping malls, hotels, office buildings, etc.), public buildings (hospitals, schools, libraries, etc.), and industrial plants. Different application areas have different requirements for product performance and appearance. For example, residences emphasize aesthetics and comfort, hospitals require antibacterial and easy-to-clean properties, and industrial plants focus on wear resistance and pressure resistance. In the entire industry chain, each link is interdependent and mutually influential. Upstream raw material price fluctuations and technological innovations directly affect the costs and product quality of midstream manufacturers, while downstream market demand changes guide the product research and development and production direction of midstream enterprises.

In recent years, the state has increasingly stringent environmental requirements for the building materials industry, successively introducing a series of policies to promote the development of green building materials. The Green Building Evaluation Standard puts forward clear indicators for the environmental performance and resource utilization of building materials. For PVC plastic flooring to be widely used in green buildings, it needs to meet environmental requirements such as low volatile organic compound (VOC) emissions and high recycling rates. This has prompted enterprises to increase investment in environmental protection technology research and development, improve production processes, use more environmentally friendly raw materials and additives, and promote the industry's transformation towards green development. Under the background of the vigorous promotion of prefabricated building policies, the convenient installation and prefabrication characteristics of PVC plastic flooring meet the development needs of prefabricated buildings. Relevant policies encourage its priority selection in prefabricated building projects, bringing new market opportunities to the industry. At the same time, the government's continued investment in public building projects, such as schools, hospitals, and affordable housing construction, clearly stipulates the selection standards for floor materials in some places. High-quality PVC plastic flooring, with its functional advantages, has a competitive advantage in the bidding of these projects, helping to expand market share.
