Zhejiang Ligao Insulation Material Co., Ltd.
Aramidic Binding Wire
The most prominent feature of aramid 1313 is that high temperature resistance is good, and it can be used for a long time without aging at 220 ° C. Its electrical performance and mechanical performance can be maintained for 10 years, and the size stability is excellent. It is around 250 ° C. The thermal contraction rate is only 1%, and it will not shrink, brittle, softened or melt at 300 ° C in a high temperature in a short time. It will only begin to decompose at a temperature of more than 370 ° C. Thermal stability is unique in organic fiber.
The aramid 1313 dielectric constant is very low, and the inherent dielectric strength allows it to maintain excellent electrical insulation under high, low, and high humidity conditions. MM2 is the best insulation material in the world. The chemical structure of the Aracea 1313 is abnormally stable. It can withstand most of the corrosion, hydrolysis and steam corrosion of most high -thick and unable to inorganic acid and other chemicals. The disadvantage is poor light resistance.

The aramid yarn can be used as a latitude and weft yarn, protective clothing, high temperature gloves, high -temperature filter -resistant sewing threads, etc.
Aramid 1313 Performance: Aramid 1313 is the polychenyl -merazhenylene amine, which is an aromatic polyamide fiber. It is a high -tech special fiber that develops fast and comprehensive performance in the world today. Mechanical performance, it is widely used in terms of electrical insulation paper, high -temperature filtering materials, protective clothing, honeycomb structure materials, etc. It is an indispensable in aerospace, aviation, national defense, electronics, communication, environmental protection, oil, chemical, marine development and other high -tech fields. Important basic materials.
Heat stability: The medium -in -the -alarm fiber has very good thermal stability. It will not melt at high temperature for a long time. 1000H is placed in a dry heat in 200 ° C. The mechanical strength remains 75%. 1000H is placed in the state, and its mechanical strength can maintain more than 60%.
Flame retardant performance: The medium -aravarous fiber is a kind of flame retardant fiber. Its extreme oxygen index LOI value ≥28%, which will not burn, melt or produce droplets in the air. ℃) Start decomposition.
Electric insulation: The medium of the aramid fiber has good electrical insulation performance. The insulation paper made for raw materials can reach the H -level insulation level. It is widely used in high -level transformers, electrical insulation, mining motors and other products.
Chemical stability: The aramid fiber has a very excellent performance of most chemicals. It can resist most of the high -thick and inorganic acid, and the alkali resistance is better at room temperature.
Good mechanical characteristics: The low -rigidity and high extension characteristics of the aramid fiber can be processed with conventional textile machinery. Its short fiber can be processed into a variety of fabrics and non -woven fabrics; its long silk available available; Generally, long silk manufacturing equipment is processed into a variety of pure fabrics and blended fabrics.
Radiation resistance: The radiation performance of α, β -rays and ultraviolet light of the aramid fiber is very excellent. For example, when β -ray radiation is accumulated to 1,000 MRAD, its strength remains unchanged.
