This material is a polyvinyl chloride (PVC)-coated or laminated polyester, which makes it water- and air-tight. However, sewing the seams can cause leakage due to needle perforations. For this reason, we opt to weld PVC-coated and PVC-laminated materials when a completely leak-proof seal is required.
Ethylene: A hydrocarbon derived from crude oil or natural gas.
Chlorine: Extracted from salt (sodium chloride) through a process called electrolysis, which separates chlorine from sodium.
Nylon and polyester fabrics can be coated with Thermoplastic Polyurethane (TPU) or Polyvinyl Chloride (PVC) on one or both sides. As previously stated, RF welding requires these thermoplastic layers; otherwise, the nylon or polyester material must be sewn.
