WHAT IS PVC TARPAULIN FABRIC ?
Polyester coated with polyvinyl chloride (PVC) is the most commonly selected material for tensile membrane structures. PVC is chosen for its excellent strength, waterproof properties, flexibility, transparency and durability. It is the most versatile and cost effective traction fabric, and satisfies a wide range of colors and application needs, both permanent and temporary. PVC is treated to be resistant to stains, fire and UV rays.
The approximate useful life of the design of polyester fabric covered with PVC is 15 to 30 years, depending on the grade of PVC selected, the location and exposure to environmental contamination. PVC fabric warranties can vary from 5 to 15 years, depending on the supplier and the application.
The PVC fabric reflects about 89% of the solar energy, which allows a visible transmission of 9% through the fabric. The speed of transmission depends on the color of the fabric, the coatings, the impressions and the surroundings. These coatings may contain anti-fungicides. Therefore, the stronger the self-cleaning properties of the fabric, the lower the light transmission due to the adherence of the dirt and the aging of the fabric.
PVC polyester is used in structures around the world and in all environments. Applications include: covered corridors, parking structures, entrances, outdoor classrooms, playgrounds, sports court enclosures, swimming pool enclosures and event spaces.
PVC is a resistant fabric that can be folded, which makes it ideal for retractable and temporary structures such as tents, warehouses, remediation and mining structures, which must be disassembled and stored frequently.
With the ability to print on the fabric with ease, PVC is often used in projects where the brand is important.
PVC can be altered to manipulate the sound absorption rate of the structure. Various coatings can be applied to PVC depending on the requirements of the structure. For example, an indoor aquatic center will use PVC that has been specifically treated to absorb as much sound as possible, while a room or small area will benefit from strong acoustic retention.
PVC-coated polyester requires little maintenance, although it requires more frequent maintenance than self-cleaning PTFE and ETFE. The frequency of cleaning depends on the location of the structure, exposure to environmental contaminants and the coating of the fabric. Lacquers and other coatings can be added to the fabric to significantly increase the life and decrease the need for maintenance.
PVC is classified as a recyclable fabric and, therefore, is an increasingly popular option for ecological construction as an alternative to rigid roofing. Although there are many PVC recycling processes, the most common practice is to melt the fabric that is to be reproduced. The process does not affect the useful life of recycled PVC.
