Size matters: Yarns and compatible sizes launched

AGY has introduced of a range of S-2 Glass and E-Glass yarns complete with thermoplastics compatible sizes for use in woven fabrics and other conversion steps.

The new yarn products have a sizing system tailored to achieve the optimum bond between the fibres and the thermoplastics but allow the use of the fibres in traditional glass fibre conversion processes.  Some fibre manufacturers have a size system that works for several polymer systems; however, according to AGT, the tailoring of its sizing systems shows improved performance over these multi-use systems as they are designed to meet the requirements of a much narrower range of polymers..

The new sizing systems are designed to work with many polymer chemistries and are available on a range of fibre diameters and are suitable for a range of high temperature resin systems such as PEEK, PEKK, PEI, PPS as well as engineering resins such as PA 6, PA6.6, PA11, PA12, PC, and PBT. The sizing can be supplied on E-Glass and S-2 Glass based yarns as well as existing system used on ZenTron rovings, S-2 Glass assembled rovings and chopped glass fibre formats.
