Closed-cell PVC (Polyvinyl Chloride) foam is a sealed rigid foam material whose structural characteristic is that the bubbles are completely enclosed inside the foam, which makes it have excellent thermal insulation and waterproof properties and high mechanical strength.

Features of Rigid PVC foam

Lightweight

PVC foam is very light relative to its volume, making it easy to transport and install.

High strength and rigidity

Despite its light weight, PVC foam has high strength and rigidity.

Good Water Resistance

PVC foam does not absorb water and has excellent moisture resistance, making it suitable for humid environments.

Chemical Resistance

It has good resistance to many chemicals (such as acids, alkalis, and solvents), allowing it to maintain stable performance in harsh environments.

Excellent Thermal Insulation

Low thermal conductivity provides excellent thermal insulation, making it an ideal choice for building insulation and refrigeration applications.

Flame Retardant

PVC foam has good flame retardant properties and meets construction and industrial safety standards.

Easy to Process

It can be easily cut, engraved, drilled, and thermoformed to meet different design needs.
