It is a carbon fiber reinforced plastic (CFRP) based on thermoplastic resin. It possesses high heat resistance and high chemical resistance, which were not achievable with conventional thermosetting resin CFRP. Additionally, conventional CFRP uses thermosetting resin, which requires a long time for molding, making it unsuitable for mass production, and it has difficulties in molding complex shapes. With CFRP based on thermoplastic resin, it is possible to mold complex shapes in a short time using thermal press molding. 【Features】 - Excellent impact strength and creep characteristics - High heat resistance - High chemical resistance - Lightweight For more details, please contact us or download the catalog.

There are two types of KRECA felt: products made with petroleum pitch-based carbon fibers and those made with rayon-based carbon fibers. The petroleum pitch-based felt (KRECA Felt C, G) is a low-density non-woven fabric formed by needle punching KRECA tow. It is utilized as an internal insulation material in furnaces used at high temperatures above 1000°C, such as in vacuum deposition and vacuum sintering furnaces, taking advantage of its heat resistance and thermal insulation properties at high temperatures. Additionally, it is used as a protective material in filters and in workplaces that involve high-temperature operations or corrosive chemical solutions, leveraging its corrosion resistance. There are carbon grade and graphite grade options, each available in two different weights. The rayon-based felt (KRECA G Felt) is a product that has been carbonized from needle-punched rayon fibers. Compared to petroleum pitch-based felt, it features a higher density and uniform thickness. 【Product Lineup】 ○ KRECA FELT C-G (KRECA Felt C-G) Petroleum pitch-based ○ KRECA FELT X (KRECA Felt X) Rayon-based For more details, please contact us or download the catalog.
