AGY recently introduced S-1 Glass high performance glass rovings for use in long fibre reinforced thermoplastics (LFT).
Designed for industrial applications, these high performance glass fibres allow new levels of mechanical properties to be developed in a thermoplastic with much lower levels of glass fibre filler – allowing for better processing and higher impact performance.
AGY developed S-1 Glass in response to the need for higher performance glass fibre at a lower cost. “S-1 Glass bridges the cost and performance gap between E-Glass and higher performance glass such as our S-2 Glass fibres,” said AGY New Business Development Manager, Iain Montgomery.
“Its excellent balance of performance and cost is enabling manufacturers to maximize the benefits from high strength glass fibre rovings and allowing exciting new applications to be developed,” he added.
According to AGY, studies have shown that a 32% of S-1 Glass fibre content in a long fibre thermoplastic can deliver the same performance as a 60% of an E-Glass filled product.
“Reduced fibre content levels mean higher impact levels, better aesthetics and easier processing of the resins,” explained Montgomery. “Alternatively, going to high levels of fibre content with S-1 Glass would allow new applications to be found due to increases in mechanical performance from these high performance fibres.”
S-1 Glass is designed for use with a broad range of thermoplastic resins such as PC, PEI, PBT and PA 6.6. Compared to traditional E-Glass solutions, S-1 Glass has higher hydrolytic stability, a 30% improvement in tensile properties and an 18% improvement in tensile modulus.
S-1 Glass is available as a roving for use in long fibre reinforced thermoplastics and is also available in chopped form for glass filled polymers.
