AGY Expands Sizing System Selection in Response to Industry Demand

19 March 2013

AGY has expanded its range of sizing systems designed to work with a wide range of polymer chemistries.

According to AGY, the new formats and products were developed in response overwhelming industry interest in its initial sizings introduction in 2012.  These newest products have demonstrated considerable improvement in performance over traditional glass fillers in a range of different polymer systems with a 30% improvement in tensile strength and modulus and 30% improvement in both notched and un-notched impact performance over E-Glass or 15% improvement in tensile strength and modulus and 25% improvement in both notched and un-notched impact over competitive high strength glass products seen in several high performance polymer systems.

According to Drew Walker, President of AGY, "We have worked hard with end-users to ensure the sizings are available in the format and glass chemistries required for a number of developmental products in industries such as aerospace, sporting goods, consumer electronic enclosures and medical devices."

The interest generated by AGY's 2012 sizings launch was immediate and from various fields.  "We had expected to see interest but the speed and level of the interest surprised us," said Walker "We started to see interest for the new systems within hours and in order to meet the demand we began accelerating the development of products that were planned for later in 2013."

By moving up the development calendar for its sizing development programs, AGY says it now has a wider selection of sizing systems on more product forms to meet the demand. "These products have been shown to increase performance over traditional E-Glass formulation but also in formulations with other high performance glass fibres," said Walker. "And with our advantage in flexible manufacture we have been able to tailor solutions to the customers' requirements both in terms of resin system and product formats."

The new sizings are available in a range of fibre diameters and formats including high temperature resin systems such as PEEK, PEKK, PEI, and PPS as well as engineering resins such as PA 6, PA6.6, PA11, PA12, PC, and PBT. Sizings can be supplied on S-2 GlassR and   E-Glass yarns, ZenTronR rovings, and S-2 GlassR assembled rovings. They can also be supplied as chopped fibres in a variety of lengths.
