Chopped Aramid

Chopped Aramid is a special fiberan which has excellent high temperature resistance and high stability .It can be used in more than 10 years in 220 degree, at 370 degree Only a small amount of gas is decomposed; It is fire retardant and occurs surface carbon high temperature , with electric insulation, resistance to breakdown voltage aramid insulation paper may reach 10 million volts / mm. In addition, a spinning, chemical stability and resistance to radiation resistance, the electrical insulation paper, high temperature filter material, protective clothing, fire fighting clothes, cellular structure material has a wide range of applications. Kevlar is basic and important material for high-tech fields such as the Aerospace, aviation, defense, electronics, communications, environmental protection, petroleum, chemical, marine development and so on.
