This is a composite reinforced fiber yarn based on special non-combustible fibers, which addresses the shortcomings of inorganic fiber materials, such as brittleness and susceptibility to friction, through a composite technology with ultra-heat-resistant functional resins. It imparts various added values such as flame resistance, chemical resistance, slip properties, and bend resistance. A special selective heating method is used during the curing process to prevent fiber degradation, resulting in a supple and soft yarn.

Skybond is a varnish based on the most thermally stable aromatic polyimide. It was developed by Monsanto in the United States, and I.S.T acquired the manufacturing and sales rights in April 1996, producing it at the Monsanto Indian Orchard plant in Massachusetts. However, in 2014, the plant was relocated, and it is now produced at the I.S.T New Jersey plant. Skybond can form extremely excellent polyimide prepregs and honeycombs with high thermal resistance and flexibility by combining with high-strength heat-resistant fibers such as glass fibers, carbon fibers, and aramid fibers. It can also be used as a heat-resistant adhesive and sealant. Its applications are mainly in the aerospace field, used in aircraft structural materials, jet engine covers, and wing components. Additionally, taking advantage of its excellent heat resistance, it is used as insulation covers for structures and engines that operate at high temperatures. Heat-resistant bearings and bushes utilizing powder molding properties are also used in a wide range of fields, including office automation equipment. The resin's exceptionally high thermal stability, mechanical and electrical properties, and high reliability are backed by years of proven performance, and its applications continue to expand into aircraft and industrial equipment.

Polyimide resin was developed by DuPont in the 1960s and has since been widely used, ranging from advanced materials for space development to everyday electrical and electronic devices. The resin's excellent thermal stability, mechanical and electrical properties, and high reliability are backed by years of proven performance, and its applications continue to expand today. Our company acquired the manufacturing and sales rights for the coating-forming varnish, Pylar M.L., from DuPont in 1994, and it is still produced at I.S.T (USA) within the DuPont facility in Parlin, NJ, supplying customers worldwide. Pylar M.L. is a polyamic acid solution (polyimide precursor) formed by the polycondensation reaction of aromatic diamines and anhydrides. By coating with Pylar M.L. as the base material and drying and curing at high temperatures, a polyimide coating with excellent properties can be obtained.

It is a foam plastic material with heat resistance up to 330℃, suitable for use as thermal insulation, cushioning material, and lightweight material at temperatures above 100℃. A significant feature is its ability to freely control the foam ratio (density) compared to other polyimide foams, allowing for the production of soft, lightweight low-density foams to hard, solid forms. Furthermore, it can be combined with other components for modularization (composite use), and by dispersing conductive fillers within the foam, it can also be applied as a lightweight electromagnetic wave absorber.
