PVC tarpaulin for air duct

PVC air ducts are fabricated from PVC resin, which is processed into various shapes, typically in the form of tubes or channels. The material can be rigid or flexible. Rigid PVC ducts are formed into fixed - shape pipes with high structural stability, often used in permanent installations where a stable airflow path is required. Flexible PVC ducts, on the other hand, consist of a PVC - coated fabric or a coiled PVC structure, allowing for easy bending and installation in tight or irregular spaces. They usually have internal wire helixes for added strength and shape maintenance during use.

The most popular specs are 340gsm laminated fabric and 650gsm coated fabric.
