PVC foam board and traditional PVC sheet: performance and application comparison

In today's diversified material market, PVC (polyvinyl chloride) materials have occupied an important position in many industries with their excellent durability and plasticity. As an innovative form of PVC material, PVC foam board stands out in many application scenarios with its unique foaming structure and excellent performance. This article will explore in depth the performance differences and application advantages between PVC foam board and traditional PVC sheet.

Excellent performance of PVC foam board
PVC foam board, as the name suggests, is a sheet with a porous structure formed by introducing a foaming agent into the PVC substrate and undergoing a special process. This foaming structure gives PVC foam board a series of remarkable performance characteristics.

Sound insulation and sound absorption performance: The tiny bubbles in the foaming structure can effectively absorb and disperse sound waves, making PVC foam board excellent in sound insulation and sound absorption. This feature makes PVC foam board an ideal decorative material in occasions where noise interference needs to be reduced, such as conference rooms, music rooms, theaters, etc.

Thermal insulation and heat preservation performance: The porous structure also enhances the thermal insulation and heat preservation ability of PVC foam board. Air is a poor conductor of heat. The large number of air gaps in the foam structure effectively blocks the transfer of heat, so that the PVC foam board can maintain a relatively stable indoor temperature in cold or hot climates.

Flame retardant, moisture-proof and mildew-proof: PVC foam board also has good flame retardancy, which can delay the spread of fire to a certain extent, buying time for personnel evacuation and fire extinguishing. At the same time, its moisture-proof and mildew-proof properties also make it less susceptible to damage in a humid environment, ensuring its service life and aesthetics.

Lightweight and convenience: Compared with traditional PVC sheets, PVC foam boards are lighter in weight due to the existence of foaming structure, and storage, transportation and construction are more convenient. This not only reduces transportation costs, but also improves construction efficiency, bringing more convenience to users.

Limitations of traditional PVC sheets
Although traditional PVC sheets also have certain corrosion resistance and processability, their performance in sound insulation, heat insulation, and heat preservation is relatively weak. Although its hardness and strength are high, this also leads to a corresponding increase in its weight and cost. In the pursuit of lightweight, energy-saving and environmental protection today, the application of traditional PVC sheets in some fields has been limited.

Application scenario comparison
PVC foam board has been widely used in many fields due to its excellent performance characteristics. For example, in the construction industry, it is used as wall insulation material, roof insulation layer, floor material, etc.; in the advertising industry, PVC foam board has become the preferred material for making display boards, signboards and other advertising products due to its light weight and easy processing characteristics. Traditional PVC sheets are more used in occasions with high hardness and strength requirements, such as the corrosion-resistant layer of chemical equipment and the production of packaging materials.

PVC foam board has excellent performance in sound insulation, sound absorption, heat insulation, and thermal insulation due to its unique foaming structure and excellent performance characteristics, and has been widely used in many fields. In contrast, although traditional PVC sheets still have advantages in some aspects, in the pursuit of high performance and lightweight today, its application range has gradually been challenged by new materials such as PVC foam board.
