SABIC introduced NORYL GTX 9500 resin, delivering dimensional stability under hot and humid conditions, addressing the challenge for highly demanding automotive applications.
GTX 9500 retains a better balance of mechanical properties when exposed to heat and humidity typical of automotive under-hood environments, than polyamide (PA) resins (PA66 and PA6) and comparable high flow, high-temperature performance. Its dimensional stability and mechanical property retention under a wider range of temperatures and humidity can open opportunities for thin-wall designs that reduce weight. Target applications for GTX 9500 are vehicle junction boxes, connectors, and other applications requiring dimensional stability.
GTX 9500 could potentially be used as the base resin in carbon fiber-reinforced thermoplastic composites used in structural and body components and for applications in the industrial, aerospace, and marine markets.
PA resins tend to absorb moisture and water especially in elevated temperatures can cause softening, loss of stiffness, and warping. GTX 9500 offers significantly lower water and moisture uptake than PA in high heat conditions up to 150 degrees Celsius. GTX 9500 absorbed 21% less moisture at equilibrium than PA66, and 58% less than PA6.
GTX 9500 material surpassed PA in dimensional stability when moisture absorption was equal. GTX 9500 had a total dimensional change (flow direction and crossflow direction) at equilibrium of 0.29% while PA66 has a total change of 84% and PA6 had a total change of 165% higher than GTX 9500. This stability benefits moisture-sensitive applications, including reducing warping to minimize scrap rates and enabling designs with thinner walls to support light-weighting.
GTX 9500 also demonstrates exceptional retention of mechanical properties – flexural modulus, tensile modulus, and flexural strength – under wet conditions compared to PA66 and PA6. GTX 9500 surpasses incumbent NORYL GTX grades based on PA in terms of water and moisture uptake, dimensional stability, and property retention and GTX 9500 resin is available globally.
