RS TENSILE PVT IN INDIA PVC Coated Polyester: PVC coated polyester can be a great material choice for permanent tensile fabric structures. PVC coated polyester is known for its excellent strength, flexibility, translucency and affordability compared to PTFE coated glass cloth and ETFE. Tensile strength can be defined as the maximum stress that a material can bear before breaking when it is allowed to be stretched or pulled. Tensile strength is often referred to as ultimate tensile strength and is calculated by dividing the peak tension force the sample withstands by its cross sectional area. A tensile tester is used to measure tensile strength. A load cell is fitted to the tensile tester to measure tensile force. Tensile strength is one of the most important and widely measured properties of materials used in structural applications.
