AGY have announced the introduction of new sizing systems designed to make the full range of AGY rovings and yarns compatibility with a wide range of thermoplastic resins from engineering materials including polybutylene terephthalate (PBT), polycarbonate (PC), and polyamide 6 and 6.6 (PA6 and PA 6.6) as well as high performance materials including polyetheretherketone (PEEK), polyetherketoneketone (PEKK), polyamide 11 and 12 (PA11 and PA12), and polyetherimide (PEI).
The new sizing compositions are designed to be used for rovings or yarns for the manufacture of products such as tapes and chopped fibres in 0.125 in. (3.2 mm) and 0.25 in. (6.4 mm) lengths for compounding into thermoplastic materials. The sizings have been evaluated on a range of different AGY products and have proven to offer increased mechanical and impact performances over traditional chopped fibres. The new sizings were developed for applications where a range of different thermoplastic resins are used.
Sizings can be supplied on S-2 Glass and E-Glass fibres directly from AGY in either chopped or continuous forms. They can also be offered on fibres outside of the traditional sphere of chopped fibre diameters, offering additional performance advantages over traditional chopped or roving solutions.[raw][connections id=’106′][/raw]
