Polyetherimide fiber

Author:admin   AddTime:2021-10-02

Utem fiber is a kind of thermoplastic fiber, which can be spun by melt method. In 2003, GE Company and FiberInnovation Technology Company cooperated to melt-spin the Ultem resin of CE Company to obtain polyetherimide (Utem, PEI) fiber. This polyimide fiber was originally intended to use its flame retardancy for bedding, which can meet the flame retardant requirements of California Technical Bulletin (TB) 603 standard for bedding.

In 2007, GE sold the plastic part to SABC for $11.6 billion, and SABIC Innovative Plastics continued to develop this fiber. They announced on June 30, 2011 that Japan Wool Textile Company, a subsidiary of the NKE Group, would blend this fiber with wool and other fibers for use in high-end work clothes and protective clothing. This kind of clothing combines the two functions of comfort and protection, and has the properties of halogen-free flame retardant and resistance to ultraviolet radiation. Unlike traditional aramid fibers, Ulem fibers can be dyed into various colors using the general method of polyester fibers.



On October 2, 2012, SABC's Innovative Plastics company exhibited the first fireproof pad that was jointly developed with National Nonwovens and is suitable for all aircraft seat covers at the aircraft interior exhibition. The trade name is Ultra-Protechtor fire. blocker. This product not only has high flame retardancy, but also has durability and flexibility, becoming a replacement product for aramid. Ulra-Protechor" fire blocker has high LOI, low calorific value, low density, low water absorption, which can reduce aircraft quality and fuel consumption, which is the main goal that the aircraft manufacturing industry has been concerned about (Table 6-3). The new product can be used with leather, synthetic leather and various fabrics to develop the next generation of innovative products to meet the new requirements of industrial safety, and to provide aircraft manufacturers with excellent fire protection pads. Uem fiber can be full of Federal Aviation Administration (A) FAR 25.853 As a rule, natural flame-retardant products do not contain fillers that can produce volatile organics.
