KURECA - Carbon Fiber for Industrial Applications
Kureha Corporation has pioneered the development of pitch-based carbon fiber under the brand KRECA, first successfully commercialized in 1970. The KRECA carbon fiber, made from petroleum pitch, is renowned for its high purity, flexibility, and adaptability across various industrial applications. The product line includes KRECA FR, known for its exceptional heat resistance and suitability as insulation in inert atmosphere high temperature furnaces, KRECA Chop, which is used in compounding with synthetic rubbers and plastics due to its low heat distortion properties, and KRECA Felt, used for furnace repairs thanks to its flexibility and excellent insulating qualities. Kureha has a robust global production and sales network, with facilities in key regions that efficiently meet international market demands.
A pioneering pitch-based carbon fiber material incorporating a range of technologies
KRECA is a carbon fiber made from petroleum pitch. In 1970, Kureha became first in the world to successfully develop an industrial manufacturing process for pitch-based carbon fiber. The high purity, fiber flexibility, and broad product lineup has made KRECA highly regarded by industries around the world.
