FIRST FIBRE® Fibrid

Product Name : FIRST FIBRE® Fibrid
 Product Introduction: FIRST FIBRE® Fibrid is a meta-aromatic polyamide floccule fibrous material which possesses excellent thermal stability (can be used for more than 10 years at 220 °C, 65% of mechanical strength retained after being heated at 240 °C for 1000 h, slight amount of gas released upon heating above 370 °C), flame resistance (self-extinguishing, surface carbonization upon combustion at high temperature, not combustion-supporting, produces no molten drops), electrical insulating property (breakdown voltage of aramid insulating paper being up to 10 kV/mm), chemical stability, cohesive and heat bonding properties. It has found widespread applications in electrical insulating paper, high-temperature-resistant filtering material, protective clothing, honeycomb structure. It is regarded as an important basic material in high-tech fields such as aerospace, aircraft, national defense, electronics, communication, environmental protection, petroleum, chemical engineering and ocean exploration.
 Main Technical Index: intrinsic viscosity≥1.6-1.8, absolute dry rate≤15%, original beating degree(35~45)oSR, thermal shrinkage at 240°C≤20%.
 Product Specification: FIRST FIBRE® Fibrid is divided into first grade product, second grade product and third grade product according to the index content.
