The combination of rigid PVC (polyvinyl chloride) plastic and closed-cell PET (polyethylene terephthalate) foam provides unique properties that allow the material to be used in a variety of industries and applications.
Lightweight
The PET foam core significantly reduces the overall weight of the material, making it an excellent choice for applications where weight reduction is a key factor.
High Durability
PVC is known for its resistance to wear, abrasion, and impact, while PET foam adds structural integrity without the extra weight.
Chemical and Moisture Resistance
PVC is naturally resistant to moisture and chemicals, which makes this composite material ideal for environments with high humidity. The PET foam core is also water- and chemical-resistant, preventing it from degrading over time.
