PVC Foams.

PVC foam is a lightweight, durable material used in a variety of industries. Common applications include sealing, insulation, cushioning, sealing strips, signage, and components in automotive and construction sectors, among others. Its resistance to moisture, chemicals, and UV exposure makes it suitable for both indoor and outdoor environments.

PU (polyurethane) and PVC foams serve similar purposes but differ in composition and performance. PVC foam is generally denser and more resistant to moisture and chemicals. It's often chosen for industrial or external use. PU foam is softer and more elastic, making it better suited to applications that prioritise comfort, such as seating and mattresses.

PVC foam can tolerate moisture due to its closed-cell structure, which prevents water from being easily absorbed. This makes it a good choice for damp environments, including sealing and insulation tasks where exposure to water is likely.

When used correctly —avoiding prolonged submersion, excessive heat, or physical overloading—PVC foam can remain in good condition for many years. Depending on the type of PVC foam it can resist UV light, moisture, and chemicals, which helps maintain its structure and function over time. In many environments, it can remain effective for decades, offering good value for long-term applications.

PVC foam is considered strong relative to its weight. It provides reliable support and impact resistance without being heavy, making it practical for packaging, construction panels, and other uses where weight is a factor. It is sturdy enough for both structural and cushioning purposes.

PVC foam helps reduce noise thanks to its cellular makeup, which can absorb and dampen sound. While it is not fully soundproof, it’s commonly used to control noise levels in industrial, automotive, and building applications, often in combination with other materials for enhanced acoustic performance.
