#Does nylon shrink free#
This alternative material applies greater force as curing temperatures increase, ensuring the result is properly laminated and free from voids, volatiles like gasses or vapor, and other foreign object debris. It’s at this moment that greater compressive force is needed, and that’s exactly what Hi-Shrink Tape provides. As temperatures increase during the curing process, the nylon will begin to relax - right when the resin or rubber begins to drop in viscosity and flow. Additional layers of the material are needed as well to provide more compression. When applied, woven nylon tape or cloth will only provide compaction according to the tension with which it is applied to the layup or product. Additionally, if heat and pressure are the only variables involved in an application, Hi-Shrink Tape and an oven are all that is needed - replacing the need for an autoclave. It’s even available on traverse-wound spools for processes that require continuous lengths of tape. This enables both hand taping as well as use of automation equipment like winders, making Hi-Shrink Tape a more viable solution for production facilities with high throughput. While both material types can be applied using machines, Hi-Shrink Tape is generally faster and easier to apply because it can be produced on different-size cores. Here are several key advantages of Hi-Shrink Tape over woven nylon tape. Instead, even greater compressive force is applied to the layup or product as the temperature rises, ensuring consistency and an overall more uniform output. Unlike woven nylon tape and other non-shrinking films like cellophane and polypropylene, Hi-Shrink Tape does not relax as curing temperatures rise. It is most often made of polyester, ETFE, and polyimide. Hi-Shrink Tape is a heat-shrinkable tape that applies compressive force to a layup. Fortunately, other solutions are available beyond woven nylon tape that can be used for compaction and vulcanization needs - and provide additional value-added benefits. For their clients that need compaction solutions to maintain their own productivity, this is a significant concern. However, as with many other industries, companies that produce woven nylon tape and cotton strapping are experiencing production delays due to material and labor shortages. While more costly than other solutions, this advantage has made it a go-to material for applying compaction. It can be rewound after a curing cycle (provided that those cycles weren’t high-temperature), often allowing up to several uses before it must be discarded. Also referred to as sail cloth or wrap tape, woven nylon tape is a consistent choice because it’s not a one-time-use product. Rob Mehal Woven Nylon Tape is a Common Compaction Material, But…Ī variety of industries - particularly those manufacturers working with rubber - use woven nylon tape to apply compaction during their vulcanization process.
