Q Is PVC sponge waterproof?
A While traditional "PVC sponge" is often discussed in the market, there is a crucial distinction to make. Standard open-cell sponges can absorb water if the surface layer is breached. However, our premium Closed-cell Foamed Synthetic Leather is 100% inherently waterproof. The advanced closed-cell structure completely blocks moisture and liquid penetration from the inside out, making it the ultimate superior choice for marine decking, medical rehab mats, and spill-prone commercial environments.

Q What is the difference between PVC and foam PVC?
A The primary difference lies in the internal structure and physical properties. Standard flexible PVC is typically a solid, dense layer. In contrast, foam PVC (specifically our Solid-skin Foamed Vinyl) undergoes a specialized high-foaming process where millions of microscopic air pockets are uniformly created within the material's core. This advanced process results in a material that is significantly lighter, incredibly softer, and possesses excellent compression recovery (rebound)—making it far superior to standard PVC for ergonomic support, anti-fatigue matting, and acoustic insulation.

Q How thick is foam PVC?
A The thickness of flexible foam PVC depends heavily on the manufacturer's production capabilities. As a leading factory with industrial-scale customization, we offer an extreme dimensional range. Our premium pvc foam rolls and Heavy Duty Expanded Vinyl are meticulously engineered from ultra-thin precision layers starting at 0.5mm (ideal for electronic gaskets and automotive linings) all the way up to an industry-leading 13mm (designed for extreme impact absorption in gym underlays and livestock matting)

Q What is PVC foam?
A In the context of flexible roll materials, PVC foam—often referred to by professionals as Expanded Vinyl Fabric—is a high-performance composite material. It is manufactured by utilizing advanced foaming technology to expand PVC resin, creating a dense, micro-cellular core. This structural transformation yields a material that offers exceptional shock absorption, ergonomic rebound, and thermal insulation, serving as the perfect substrate for automotive NVH solutions, premium underlayments, and heavy-duty matting.
