Aramet® Spunlace
Aramet® Spunlace
Aramet® Spunlace is a high-temperature resistant insulation product with an excellent balance of physical, temperature and electrical properties which in turn provides characteristics such as high inherent dielectric strength, mechanical toughness, flexibility and resilience. This product is produced by interlacing meta-aramid (i.e. Aramet®) fibers without the use of binding agents to afford a more porous product which is also durable, soft and comfortable.
For electrical applications, Aramet® Spunlace is usually impregnated with a varnish or resin. Due to the inherent chemical resistance of aramids, Aramet® Spunlace is compatible with virtually all classes of electrical varnishes and adhesives. Furthermore, transformer fluids including minerals, silicone oils and other synthetics are also compatible with Aramet® Spunlace.
