AGY Introduces New Thermoplastic Sizing Systems

March 11th, 2014 by

AIKEN, SC USA – (March 11, 2014) – AGY has introduced over the last 2 years a number of innovative sizing systems for use in thermoplastic composite applications, the continued growth in the use of these materials has been evident in the number of requests AGY has handled during this time and the diversity of the markets they will serve. Now AGY announces the introduction of a range of S-2 Glass® and E-Glass yarns complete with thermoplastics compatible sizes for use in woven fabrics and a range of other conversion steps.

The new yarn products launched by AGY have a sizing system tailored to achieve the optimum bond between the fibers and the thermoplastics but allow the use of the fibers in traditional glass fiber conversion processes. Some fiber manufacturers have a size system that works for several polymer systems; however the tailoring of the sizing systems by AGY shows improved performance over these multi-use systems as they are designed to meet the requirements of a much narrower range of polymers. In today’s demanding markets this ability to offer a unique solution to markets such as aerospace, sporting goods, consumer electronic enclosures, and medical devices has led to a significant demand for new yarn type products.

“The interest in our new sizing systems has continued at a high pace. We started with products aimed for the formulators who used traditional chopped fibers and quickly were seeing requests for rovings and now into our unique range of S-2 Glass yarns,” said Drew Walker, CEO of AGY. “The development for our sizing programs into a range of products has been fast, our initial developments gave us good information on resin compatibility and with our experience in direct sized fibers we have been able to translate those sizes designed for chopped products into the products requested for S-2 Glass yarns. The whole range of thermoplastic products have been shown to increase performance over traditional E-Glass but also over other high performance glass fibers and with AGY’s advantage in flexible manufacturing we have been able to offer solutions in formats and compatibility to meet diverse customer requirements”.

The new sizing systems are designed to work with a wide range of polymer chemistries and are available on a range of fiber 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 asexisting system used on ZenTron® rovings, S-2 Glass assembled rovings and chopped glass fiber formats.
