Vinyl coated polyester is a material frequently used for flexible fabric structures. It is made up of a polyester scrim , a bonding or adhesive agent, and an exterior PVC coating. The scrim supports the coating (which is initially applied in liquid form) and provides the tensile strength, elongation, tear strength, and dimensional stability of ...
The thread used to stitch modern marine type canvas is typically made from Polyester or PTFE with sizes ranging from #69, #92, #138. [8] Polyester thread is widely available and relatively low cost compared to PTFE, but PTFE thread has become increasingly popular due to its far greater resistance to ultraviolet radiation a chemical ...

Vinyl-coated polyester is manufactured in large panels by heat-sealing an over-lap seam with either a radio-frequency welder or a hot-air sealer. A proper seam will be able to carry the load requirements for the structure. The seam area should be stronger than the original coated fabric when testing for tensile strength.
It is used in the manufacture of backpacks, tarps and tarp tents, bivy bags, etc., particularly by ultralight backpackers. Several types of silnylon are produced. The common type is a quiet, silky, very slippery fabric. The variant known as "crisp silnylon" is lighter, but brittle, noisy in movement, and easily torn.
Built-up roofs (BURs) consist of multiple plies of bitumen-coated organic felt, polyester felt, or coated fiberglass felts. Three to five plies of felt are laminated to each other and to the substrate with hot asphalt, coal tar pitch, or made-for-purpose cold adhesive.
