PVC crust foam board innovates bathroom applications, Yongte plastic machinery equipment leads the upgrade of production technology
The quality and durability of bathroom facilities depend largely on the selected materials. In recent years, PVC crust foam board has gained wide favor in the field of bathroom decoration due to its excellent comprehensive performance. Its core advantage lies in its unique structure. The surface is a dense "crust layer", and the interior is a uniform closed-cell foam core layer, forming a "sandwich" structure. This structure gives it excellent waterproof and moisture-proof properties, and the measured water absorption rate is less than 0.1%, far exceeding traditional wood boards. For bathroom cabinets, partitions and other products that are exposed to high humidity environments for a long time, it can effectively prevent mold and deformation. In terms of cleaning and maintenance, its smooth and dense surface makes it difficult for stains to adhere, and the cleaning efficiency is increased by more than 50% compared to tile walls. At present, many boards on the market have also added antibacterial ingredients, which further enhances the sanitation guarantee capability. In addition, PVC crust foam board is light in weight, only one-third to one-half of ceramic tiles, which reduces the load-bearing burden of buildings while also being easy to process. Through cutting, engraving and other processes, various shapes can be flexibly customized, perfectly adapting to the current popular minimalist, light luxury and other design styles, and are very popular among designers.
Market data confirms its value. According to the Grand View Research report, the global PVC crust foam board market size has reached US$4.2 billion in 2024, and the growth momentum is strong. It is expected that its compound annual growth rate will remain at 6.8% between 2025 and 2030, among which the demand growth for bathroom applications is particularly prominent. Behind this trend is the continuous improvement of consumers' requirements for the quality and functionality of bathroom space, as well as the continuous construction of public bathroom projects such as hotels and hospitals. The industry generally predicts that the market size of this material in the bathroom field will grow at an average annual rate of more than 15% in the next five years.
Excellent boards are inseparable from advanced production equipment. In the field of PVC crust foam board equipment, Yongte Plastic Machinery has established a leading position with its core technology of "precise plasticization, uniform foaming, and controllable shaping". The extrusion process uses a parallel co-rotating twin-screw extruder with a length-to-diameter ratio of up to 36:1, and a temperature system with a zoned temperature control accuracy of ±1°C to ensure uniform mixing of materials and stable plasticization. In the key foaming process, whether it is the precise metering of chemical foaming agents or the high-pressure injection of physical foaming agents, the uniform distribution of bubble diameters can be achieved within the range of 50-100 microns. In the shaping stage, the unique "mold sleeve + core mold" structure shaping mold is combined with vacuum adsorption and multi-stage temperature gradient control to accurately control the thickness of the crust layer on the surface of the board between 0.1 and 0.5 mm, effectively avoiding common defects such as pores and warping.
Yongte PVC crust foaming equipment also integrates PLC automatic control system and servo drive technology, which significantly optimizes production capacity and energy consumption while ensuring high product quality. Its equipment can stably produce various types of boards with a thickness of 2-30mm and a width of 1220-2440mm, with a maximum production capacity of 500kg/h, which is about 20% lower than the energy consumption of traditional equipment. At present, the equipment has been applied to production lines by many well-known domestic and foreign bathroom brands, successfully helping customers increase product yield to more than 98%, which has greatly enhanced market competitiveness.
As the application of PVC crust foam board in the bathroom field continues to deepen and expand, Yongte Plastic Machinery is continuing to focus on technological innovation. For example, it is committed to developing more stable antibacterial and mildew-proof formulas and exploring more flexible curved surface hot pressing molding processes. Its goal is to continuously provide the industry with more competitive production solutions and promote the entire PVC crust foam board industry to develop in the direction of higher quality and higher efficiency.
