Bad Things About PVC Foam Sheet You Should Know

PVC foam board, also known as expanded PVC sheet. It is a rigid, closed-cell, foamed PVC sheet with half the density of solid PVC sheet, which gives it a lighter weight. PVC foam board is suitable for most indoor and outdoor applications due to its high usability and durability, and is an ideal alternative to wood board. PVC foam board is widely used as a multifunctional board, such as sign boards, display boards, kitchen cabinets, interior decoration, wall panels and construction. However, do you know what are the disadvantages of PVC foam board?

The softening temperature of PVC foam board typically ranges from 65°C (149°F) to 80°C (176°F). This implies that in environments with temperatures exceeding this range, PVC foam board can become soft and may even lose structural stability. Using PVC foam board in high-temperature conditions could result in material deformation, failure, or performance degradation.

While PVC foam board, as a synthetic material, lacks the natural grain patterns found in solid wood, this characteristic doesn't preclude us from enhancing its appearance by applying laminated decorative materials to its surface. This method allows us to achieve a wood-like texture and look, while still benefiting from PVC foam board's advantages like lightweight, insulation, and ease of fabrication.

White PVC foam boards used outdoors may develop a yellowing effect over time. Although the yellowing is typically mild, it might still be unsatisfactory for some customers. We recommend customers consider purchasing ivory-white PVC foam boards instead of pure white ones, or opt for PVC foam boards with enhanced UV resistance to mitigate this issue.

The density of standard PVC foam board typically ranges from 0.5 to 0.65g/cm3, which is less than half that of solid PVC sheets and comparable to some wood panels. This lightweight property ensures easy handling and straightforward installation.

PVC foam board exhibits minimal water absorption, making it highly resistant to water and moisture. This quality proves invaluable in humid environments.

Polyvinyl chloride boasts resistance to acids, alkalis, and a range of chemicals, mitigating concerns about corrosion or rust in practical applications.

PVC foam board is unappealing to termites and white ants, rendering indoor furniture crafted from it unattractive to these pests.

Common PVC foam board possesses self-extinguishing properties in fire conditions. Fireproof reinforcement variants can even meet ASTM E84 Class A standards.

PVC foam boards, compared to wooden counterparts, resist crushing and cracking in outdoor use, contributing to a longer service life. UV-resistant variants perform exceptionally well, especially when enhanced with anti-ultraviolet agents.

Depending on its density, PVC foam board can exhibit remarkable rigidity or flexibility, catering to varying strength requirements.

PVC foam board can be conveniently drilled, nailed, sawed, CNC cut, hot bent, laminated, sanded, and painted without the need for specialized equipment or tools.

PVC free foam board, one of three types of PVC foam board, offers a matte finish and ample size, making it ideal for printing and signage applications.

PVC foam boards excel in design versatility, offering an array of possibilities for cutting, shaping, and customization. This adaptability allows for the creation of intricate and diverse designs, making them suitable for a wide range of creative and practical applications.
